Bar Specification + Sizes + Theoritic Weight of Stainless Steel Hex & Square Bars & Theoritic Weight of Stainless Steel Round Bars

Stainless steel is essentially a low carbon steel which contains chromium at 10% or more by weight. It is this addition of chromium that gives the steel its unique stainless, corrosion resisting properties. The corrosion resistance and other useful properties of the steel are enhanced by increased chromium content and the addition of other elements such as molybdenum, nickel and nitrogen.
