About Stainless Steel
Stainless steel is an alloy, which is iron-based and contains various combinations of other elements to give it characteristics suitable for a wide range of applications. It is also called corrosion-resistant steel, particularly in the aviation industry.
Most stainless or heat resisting steels are either melted by the electric furnace process or vacuum arc re-melted.
Heat treatment for hardness and strength is recommended mainly for the straight chromium steels. Cold working is generally utilized for the chromium-nickel classes of steel and has the advantage of increasing strength while retaining good ductility.
