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

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

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.
