  • What is Stainless Steel?- Types, Properties, Application

    Stainless steel is a type of steel that is made up of at least 10.5% chromium, which makes it resistant to corrosion. It is an alloy or mixture of metals made up of iron, chromium, and other elements such as carbon, nickel, and manganese. The chromium in stainless steel reacts with oxygen in the air to form a thin, transparent chromium oxide ...
