Stainless Steels - Specifications
Stainless steel is essentially a low carbon steel which contains chromium at 10% or more by weight. lt is this addition of chromium that gives tale st6el its unique stainless, monsoon resisting properties. The consign resistance and other useful properties of the steel are enhanced by incased chromium content and the addition of other elements such as molybdenum, nickel and nitrogen.
