A chromium content of at least 11% is necessary for the formation of the protective layer. It is not very electrically or thermally conductive, and is non-magnetic. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes. Stainless Steel is highly ductile and has high strength.

Grade 304 of stainless steel is a standard “18/8” stainless that has high resistance to corrosion and oxidation due to the chromium content in it. It can be easily welded, has excellent toughness, even at cryogenic temperatures and can be easily fabricated. Stainless steel 304 has applications in a variety of purposes, like, in making utensils, screws, and various machinery parts.
