it quickly regenerated in the passive film is destroyed chloride

Molybdenum is chemically very stable and will not be corroded by hydrochloric acid, hydrofluoric acid, and alkali, but nitric acid, concentrated sulfuric acid, aqua regia, or is hot corrosion of molybdenum added is also an important element. Molybdenum at high temperatures can molybdenum boat solid reinforced to prevent chloride pitting, improve corrosion performance dope also. Large demand for oil has forced people to accelerate the exploitation of land and sea in deep reservoirs, and deep reservoirs often subject to corrosive hydrogen disulfide, carbon dioxide and pollution and high chloride brine, which contain molybdenum from 0.15% to 0.25% steel has been widely used.
With the deepening and worsening conditions of the drilling depth, with higher molybdenum stainless steels and nickel-based alloys, such as alloy and alloy applications will continue to increase. Since the chromium in the steel surface to form a thin passivation film naturally has a protective effect, the stainless steel having corrosion resistance. sandblasted tungsten target In fact, this passive film molybdenum make more solid, and it quickly regenerated in the passive film is destroyed chloride. Increased molybdenum content on pitting of stainless steel to improve corrosion resistance and crack. The most widely used stainless steel containing molybdenum.
