Historic low molybdenum time to get rid of winter yet
2013 年 7 月 17 日 SMM recent years, the domestic molybdenum prices have ups and downs, but the overall price trend concussion. Since the 2008 global financial crisis, molybdenum prices low DECADE.As of the 16th, the domestic content of 45% molybdenum's latest offer is about 1400 yuan / ton level, when compared with the beginning dropped by about 10 percent, fell in August 2012 historic low levels, compared with 2005 high shrink about 80 %.
According to the Shanghai Metals Market (SMM) research to understand, from mid-2012 onwards, Shaanxi, Henan, Liaoning and other companies have discontinued the main producing molybdenum insured, but the actual effect is very unsatisfactory and only in December 2012 to 2013 February, the market price due to supply reduction and steel procurement and rebound.
At present, the Shaanxi region has ore mining scale enterprises can be molybdenum (content 45%) of production costs at 1500 yuan / ton degrees nearby, and some small businesses, low-grade ore, production costs at 1600 yuan / t degrees.Below the cost line of the grim situation to make the industry initiative to stop the resurgence of the wind.
Insiders believe that the leading precious metals price trends of the industry supply and demand pattern. Prolonged downturn in the domestic steel industry in recent years, steel mills bidding prices down, as the charge of molybdenum steel product prices spread to the upstream industry chain, also involving molybdenum prices continue downward.
Looking ahead, molybdenum plating prices have fallen below the cost, but not to force the end demand, despite the supply reduction, but still difficult to translate into significant support price, it seems sluggish performance or molybdenum prices this winter will continue to

the factory resumed production is still positive.
Core Tip: This week started, manganese prices blocked, although manufacturers offer still relatively high, but difficult to be as high-priced supply downstream accepted in the short term is difficult to extend gains in manganese prices.
May 19 to August 23, manganese significant gains this week, the market price has risen 400. Because manganese spot continued tight supply, and manufacturers are reluctant now shipping, manufacturer attitude clearly reluctant to sell, hard to find cheap stock market, spot transaction prices continue to be pushed. Currently on high manganese downstream of acceptance is not high, and manufacturers in the end there are some financial pressure, is expected next week manufacturers reluctant to sell their attitude weakened, manganese prices can no longer rise.
Raw materials, prices continued to rise this week, selenium dioxide. August 23, 98% selenium dioxide quoted in 360-370 yuan / kg, compared with last week rose 20 yuan / kg. May 19 to August 23, this week, manganese, ferromanganese no significant fluctuations in the market, manufacturers offer stability. August 23, Guizhou, Hunan manganese 6517 tax factory acceptance price of 6650-6800 yuan / ton, Ningxia, Inner Mongolia 6517 tax factory acceptance silico-manganese prices in 6650-6850 yuan / ton, the South manganese 6014 taxes offer in 5350-5500 yuan / ton, Hunan, Guizhou, a group of manufacturers of high-carbon ferromanganese 65C7 tax phosphorous factory price 6050-6150 yuan / ton.
Silico-manganese market remained stable this week, factory orders is better, a slight increase in the spot price, manufacturers offer little overall change. Currently silico-manganese market is still the main focus of a new round of bidding steel price fluctuations may be no. Because manganese orders changed for the better, manganese 6014 manufacturers resume production will increase, but higher production costs molybdenum plating 6517, the factory resumed production is still positive.
This week ferromanganese market stability, the manufacturers offer the same, compared to the improvement of the order manganese, ferromanganese situation still seems difficult. Currently ferromanganese plant shutdowns is still more, because there was no significant improvement in prices and demand in the short term remains positive ferromanganese plant started.
Although the price of manganese ore imports in August is still a certain extent of decline, but the trend is better steel, silico-manganese steel tender prices in September rose slightly larger hope. August 19 to August 23, this week, in order to stabilize the overall price of imported manganese ore mainly due to lower purchases for manganese situation has not significantly improved, some miners offer still weak. Currently silico-manganese prices are still no signs of rising, and manganese factory operating rate changed little in the short term the price of imported manganese ore is still hard out of the doldrums, ore prices steady weakening operation
May 19 to August 23, manganese significant gains this week, the market price has risen 400. Because manganese spot continued tight supply, and manufacturers are reluctant now shipping, manufacturer attitude clearly reluctant to sell, hard to find cheap stock market, spot transaction prices continue to be pushed. Currently on high manganese downstream of acceptance is not high, and manufacturers in the end there are some financial pressure, is expected next week manufacturers reluctant to sell their attitude weakened, manganese prices can no longer rise.

Warmer atmosphere thick molybdenum prices
molybdenum plating market: The current low-grade molybdenum concentrate 30-38% price
1360-1410 yuan / ton degrees; conventional 40-45% molybdenum mainstream
price 1400-1430 yuan / ton level, 45% of molybdenum 1420 -1430 yuan /
ton degrees ; 47% and more high-grade
molybdenum mainstream price 1440-1450 yuan / ton degrees. Slightly
different level of turnover, while the business operations at the venue
will increase, driven by the recent market volume and price Qi Zhang
molybdenum positive signal. The molybdenum
oxide, iron and other products prices rise more obvious, and the larger
manufacturers inventory is low, such as the late demand for the release,
molybdenum prices are expected a larger increase.
Recent domestic molybdenum market actively brewing gains, prices of some products have a larger increase. In addition, by the bottom of the external molybdenum market rebound is expected to focus on domestic demand for steel products at the end of the city to pick up other favorable factors supporting the market, the market outlook for many businesses remain relatively optimistic. Molybdenum market active inquiry, cheap stock hard to find, mining companies continue to drop prices, some intermediate traders hold stocks wait and see, wait for post-market has risen further and timely shipments. Molybdenum manufacturers offer higher intentions, because the business itself is different, differences are more obvious external offer. Deep processing market was relatively poor, the slow pace of price increases, and the actual demand is still poor, high turnover weak. Saddle Ridge is expected in the short term primary molybdenum market or still are good.

price fluctuations pace slowed down, late or there are adjustments.
External Markets: Western Europe, serious deserted market demand , resulting in stainless steel and other steel products prices decline more than . Downstream market is poor, demand for raw materials is difficult to maintain , so molybdenum prices extended losses and other products . In addition, raw material prices continue to fall , but also makes stainless steel containing molybdenum price loss of support , have negative effects on the downstream relative to the overall decline is hard . U.S. molybdenum prices relatively stable , price fluctuations pace slowed down, late or there are adjustments.
Internal Market : roughly the same price a year earlier , the current domestic market by the decline more than molybdenum plating into stalemate. Product prices low , seriously affecting the factory shipments will. Molybdenum vulnerable before the trip, floor trading remains sluggish, due to increased investment risk , merchants trading deserted atmosphere ; molybdenum weak consolidation , manufacturers offer small fluctuations , tender strokes steel prices remain low. Chemical and other market manufacturers cut the sidelines. Few orders , some businesses barely maintain normal production. Molybdenum scrap market is relatively calm , some traders purchase price low , low willingness to take the goods to the seller . We expect short-term molybdenum market or remain relatively quiet state.

Chromium week assessment: chrome ore market is still active low ferrochrome dull
Core Tip: This week Port chrome ore prices remain steady the main market is still lacking positive thus stimulating the downstream plant for chrome ore purchasing enthusiasm is not high; ferrochrome manufacturers offer little change in the overall individual manufacturers offer slightly weaker , the market relatively flat; low carbon ferrochrome prices fell slightly, the market downturn has not improved.
Port this week chrome ore prices remain steady-based, so the market is still lacking positive stimulus, the lack of ore price rise opportunities. Since there is still no signs of ferrochrome market for chrome ore factory purchasing enthusiasm is not high, demand is still to be improved. Currently ferrochrome market still no signs of recovery since September high chromium steel tender price is lower than market expectations, chrome ore market activity declined again, miners continue to stay on the sidelines in the short term to stabilize the main ore price run.
This week ferrochrome molybdenum plating offer little change in the overall individual manufacturers offer a slightly weaker market relatively flat. September mills ferrochrome tender price trend is clear, as the tender price, the tender were not increased compared with August, which makes the high-chromium manufacturers still lack confidence in the market outlook is expected to recent high prices still flat chrome
Week low carbon ferrochrome prices fell slightly, due in September of high chromium steel tender unsatisfactory performance, low chromium manufacturers also had fears that the current market demand increases difficulties of low carbon ferrochrome market remained in the doldrums, the price run dominated by weak stabilization.
This week silicochromium prices remain stable, the spot last week to maintain the level of supply and demand, Sichuan silicochromium 72 manufacturers offer in 8000-8100 yuan / ton. Currently silicochromium significant fluctuations in market difficult, in September-October season in anticipation of stainless steel, ferrochrome prices of recent sharp weakening may be difficult, and the same is true of chrome silicon, silicon-chrome prices are still expected next week little changed.
Chrome market remains in the doldrums this week, spot transactions does not improve, while the manufacturers offer stable. Currently chromium low price stabilization operation, short-term demand still no signs of improvement. European chrome prices continue steady in 8500-8900 U.S. dollars / ton.

hardness sharply increased
molybdenum alloy welding characteristics of molybdenum and molybdenum alloy steel welded structure, used more often in the actual production, but because of molybdenum and molybdenum alloy and steel physical properties of a larger difference in welding process, a lot of problems. Analysis of the problem from the welding concluded, molybdenum and steel welding performance depends primarily on molybdenum and molybdenum alloy composition and performance. Iron - molybdenum alloy state diagram in Figure 1. Fe from the state diagram shows the various concentrations of Mo to form α-Fe and α-Mo solid solution. In addition you can also form two intermetallic brittle phase ε-Fe3 No2 and η-FeMo. Fe3 No2 until 1450 ℃ temperature range are relatively stable. State diagram of η-phase, there is a temperature range of its 1180 ~ 1540 ℃, when the cooling time, η-phase decomposition of ε-phase and α-phase solid solution. Molybdenum and steel welding has the following main features. ① molybdenum steels mainly depends on molybdenum and molybdenum alloy composition and performance. Molybdenum and molybdenum alloy and steel welding, when heated to 400 ℃, minor oxidation. Above 600 ℃, the rapidly oxidized to MoO3 compounds. The solubility of oxygen in the molybdenum is small, when the oxygen content increases, the formation of oxides along the grain boundaries, compounds of other impurities are also brittle phase in the grain boundary precipitates, the welding difficult. ② welding molybdenum steel, molybdenum base metal close to the side, prone to high hardness and brittleness zone, the width of up to 0.5 ~ 3μm. Here are the main component of intermetallic compounds Fe3 Mo2 and FeMo. Close to the steel base metal side than on the molybdenum base metal brittleness orientation small, but fast cooling rate after welding, the side of the base metal molybdenum appears martensite, resulting in the weld heat affected zone and the splice area embrittlement in the weld stress under the effect of severely increase the tendency to crack joint. Therefore, molybdenum and steel is a relatively poor weldability. ③ molybdenum and steel welding dissimilar weld metal consists of three parts, components and solder joints uniform. Close to the steel base metal side is made of steel and composed of an intermetallic compound phase organization, its hardness is increased dramatically; near molybdenum base metal side is made of an intermetallic compound consisting way, hardness sharply increased; weld intermediate is made between molybdenum and steel consisting of an intermetallic compound, the hardness is high. Molybdenum steel welded joint tissue components with uneven great influence on hardness, shown in Figure 2. 2, (1) is composed of an intermetallic compound of steel and the duplex structure; (2) between the steel and the intermetallic compound of molybdenum plating; (3) is a molybdenum compound and a metal phase composed of tissue. (2) molybdenum and steel welding a) molybdenum and steel welding - brazing molybdenum and steel (carbon steel, stainless steel) using welding, electron beam welding and gas welding and other welding methods, welding can be achieved - brazed joints. This welding process is the essence of the steel side of the molten metal more, and molybdenum increase the side just heating without melting or melting little liquid metal is steel formed by infiltration brazed seam. This avoids the formation of iron and molybdenum compounds Fe3 Mo2 and FeMo, the joint area embrittlement problem is solved. Molybdenum steel electron beam butt welding directly, the weld metal composition mainly 20Mo-80Fe in the Mo base material is displayed on the side of the boundary eutectic α + ε, and the formation of large intermetallic Fe3 Mo2 and FeMo. Since the presence of intermetallic compounds, the weld metal brittle and easily cracks increases, reducing the performance of the joint, its poor weldability. Therefore, molybdenum and steel fusion welding, the joint strength is not high, you should avoid direct welding, it is generally used welding - brazing.
