PRODUCT DETAILS
Product information
SS 309S stainless steel is a highly alloyed austenitic stainless steel utilized for its outstanding oxidation resistance, high-temperature, strength, and creep resistance. The lower nickel content of Stainless Steel 309, compared to Stainless Steel 310, increases its resistance to hydrogen sulfide (H2S) attack at high temperatures. It is tough and ductile and can be readily fabricated and machined. SS 309S is the low-carbon version, and is recommended for, uses where sensitization and subsequent corrosion by high temperature condensates during shutdown may pose a challenge. Stainless Steel 309S is used for its high-temperature oxidation resistance and resistance to H2S attack. 309S Stainless Steels can be roll formed, stamped and drawn readily. In-process annealing is usually needed to increase ductility and reduce hardness.
