How stainless steel is made

20-11-2006Stainless steel is an iron-containing alloy—a substance made up of two or more chemical elements—used in a wide range of applications. It has excellent resistance to stain or rust due to its chromium content, usually from 12 to 20 percent of the alloy. There are more than 57 stainless steels

How iron has shaped our world: ten things to know about

30-9-2016Iron has been used for about 5000 years. But as iron ore smelting techniques weren't widely adopted until around 1200BC, it is thought that the first iron used by humans was likely to have come from meteorites. The onset of the Iron Age saw the widespread use of iron in tools and weapons, and led to a period of great social change.
