What is Stainless steel?

A common term used to cover an entire range of iron-base alloys that are remarkably resistant to rusting and corrosion because of their chromium content. Stainless steel usually contains 70-90 per cent iron, 12-20 per cent chromium and 0.1- 0.7 per cent carbon. A chromium content of more than 10 per cent with a low carbon content makes iron rust-proof. Nickel and molybdenum may also be added to obtain an improved variety of stainless steel.
