AISI 303 Stainless Steel Bar

Shanghai Yikai Metal Products Co., Ltd can supply stainless steel 303 in various forms according to customers' requirement.Stainless steel type 303 is specifically designed to exhibit improved machinability. It is a non-magnetic austenitic stainless steel that can not be hardened by heat treatment. 303 is a corrosion resistant steel which has a high resistance to oxidation. As with all stainless steels, the rate of oxidation is greatly affected by the service atmosphere, heating and cooling cycles and design considerations. Type 303 Stainless Steel stays austenitic at all temperatures. When it is heated between 800 Fahrenheit degree and 1500 Fahrenheit degree, carbides will precipitate at the grain boundaries. When reannealed, the carbides will redissolve.
