Stainless steel is made up of iron alloys, chromium (at least 10.5%) and other metal alloys such as nickel, titanium, copper or molybdenum. Essentially, it’s a family of heat and corrosion resistant metals combined to create an incredibly useful metal. The makeup of stainless steel varies depending on its intended use and corrosion resistance requirements. Stainless steel is available in a range of grades including Austenitic, Ferritic, Martensitic and Duplex.
