Molybdenum effect
Molybdenum in pure γ-Fe in the maximum solubility of about 3%, ω (C) ≈ 0.25% ~ 0.30%, the maximum solubility in austenite is about 8%. Molybdenum in pure α-Fe the maximum solubility of about 32%, and decreased with temperature can precipitate Fe3Mo2, to obtain an age-hardening systems. Molybdenum is a ferrite forming element, capacity equivalent to chromium. In the martensitic stainless steel, molybdenum addition to improving the corrosion resistance, but also improve the hardness and strength, and enhance the secondary hardening effect of steel. The role of the stainless steel molds and cutting tools is very beneficial, usually in the martensitic stainless steel in the ω (Mo) <1%.
