This grade withstands ordinary corrosion in architecture, is durable in typical food processing environments, and resists most chemicals. The most commonly specified austenitic (chromium-nickel stainless class) stainless steel, accounting for more than half of the stainless steel produced in the world. The most common US grades of stainless steel are: TYPE 304 Since stainless steel resists corrosion, maintains its strength at high temperatures, and is easily maintained, it is widely used in items such as automotive and food processing products, as well as medical and health equipment. mechanical properties for specific temperature ranges.Selection of stainless steels are in general based on Other alloying elements added to improve the characteristics of the stainless steel include nickel, molybdenum, copper, titanium, aluminum, silicon, niobium, nitrogen, sulphur, and selenium.Ĭarbon is normally in amounts from 0.03% to more than 1.0% in some martensitic grades. Stainless steel achieve its stainless characteristic through the formation of an invisible and adherent chromium-rich oxide surface film. Stainless steels are a iron-based alloy containing at between 10.5% to 30% Cr. Stainless steels are available in the form of The metals used most commonly as alloying elements in stainless steel include chromium, nickel, and molybdenum. precipitation-hardening stainless steelsĪlloying metallic elements added during the making of the steel increase corrosion resistance, hardness, or strength.duplex (ferritic-austenitic) stainless steels.Stainless steels are in general grouped into
