stainless steel WHY DOES SOME STAINLESS STEEL CORRODE AND RUST?
Stainless Steel is the name given to iron based alloys that contain at least 10.5% chromium. Since its development elements have been added to stainless steel to increase the chromium content in order to improve its corrosion resistance. Chromium is added during the melting of the steel and forms a mixture with the iron and other alloying elements, such as nickel and molybdenum, which improves the metal’s resistance to corrosion. There are now over 50 stainless steel different grades and a lot are know by their AISI numbering system (200, 300 & 400 grades).
