Stainless steel can be an ideal material for parts and applications that require a stain- and rust-resistant surface. It is made of iron, chromium (which gives it a non-reactive characteristic) and in many cases an array of other components, including silicon, nickel, carbon, nitrogen and manganese. There are currently dozens of recognized stainless steel alloys, plus a nearly endless variety of custom formulas. Addressing the complexity and characteristics of stainless steel alloys in a foundry requires specialized knowledge and experience—like that found at PPCP.
