Stainless steel is an iron alloy, containing a minimum of 10.5% chromium. It is often combined with other alloying elements such as nickel, nitrogen, and molybdenum to create the corrosion-resistant product used in many applications. Hamilton Precision Metals offers a diverse range of 300 and 400 series stainless steels.
