专利汇可以提供Nartensitic stainless cast steel with cavitation erosion resistance专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide high mechanical strength and toughness, especially high cavitation errosion resistance to a martensitic stainless cast steel by specifying the contents of C, Si, Mn, Ni, Cr, V, etc. in the composition of the cast steel.
CONSTITUTION: This cast steel consists of, by wt., ≤0.1% C, ≤1.0% Si, 2.0W 9.0% Mn, 0.5W8.0% Ni, 11.0W14.0% Cr, 0.05W0.2% V and the balance essentially Fe or further contains ≤2.0% Mn. It is melted with a high frequency or electric arc furnace. Since the cast steel has superior mechanical strength and toughness, especially superior cavitation erosion resistance, it is suitable for casting large-sized castings such as water turbine runners, guide vanes and stay vanes for equipment for hydroelectric power generation.
