309S

309S stainless steel is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high-temperature strength, and creep resistance. The lower nickel content of Stainless Steel 309, compared to Stainless Steel 310, improves its resistance to hydrogen sulfide (H2S) attack at high temperatures.

309S Stainless Steel Plate Specification:

Thickness:0.3—100mm;width:1000—3000mm;length:3000—18000mm
