WebMar 23, 2015 · The main alloying element in Stainless steels is chromium (typically between 10-20%). Stainless Steel is valued due to its high corrosion resistance. Stainless steel is about 200 times more resistant to corrosion than mild steel. Stainless steel can be divided into five groups: WebStainless steels are iron-base alloys containing 10.5% or more chro- mium. They have been used for many industrial, architectural, chemical, and consumer applications for over a half century. Currently there are being marketed a number of stainless steels originally recognized by the American Iron and Steel Institute (AISI) as standard alloys.
