Selection of Cast Stainless Steels

The development of casting technologys has been driven by two distinct engineering perspectives. The first involves the potential economy of cast hardware relative to totally machined wrought parts and the second perspective is associated with metallurgical realities. The chemical composition and microstructure of some alloys is such that deformation processing of large ingots into wrought product forms would be problematic. In addition, the very nature of cast microstructure which in general is composed of large grains can provide benefits in high temperature creep applications.
