Stainless Steel

Stainless steel is an alloy of iron and at least 11% chromium with other metals to obtain its desired “stainless” properties. It is resistant to rusting and corrosion from the chromium content. 

The alloy's properties, such as luster and resistance to corrosion can be used in cookware, cutlery, surgical instruments, major appliances and other household products.
