JMJDWX Steel 309s Stainless Steel Sheet/Plate
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. It is tough and ductile and can be readily fabricated and machined. SS 309S is the low-carbon version, and is recommended for applications where sensitization and subsequent corrosion by high temperature gases or condensates during shutdown may pose a problem.
•Specifications: AISI 309s, ASTM 309s
•Standard: A240 480
•Finishes: Ba surface, 2b surface, No.1 (white skin), HL (wire drawing), 8K surface have excellent surface quality and good brightness.
•Applications: metal structures, Architectural applications, Food industry, chemical and oil industry, pharmaceutical industry, nuclear industry, Naval industry, non-magnetic constructions, cryogenic service, high temperature service application Steel type
•How is it Measured: thickness X width X length
•Available Stock Sizes: 1ft x 4ft, 2ft x 2ft, 2ft x 4ft, 4ft x 4ft, 4ft x 8ft, 4ft x 10ft or Cut to Size
Mill tolerances on thickness & flatness applies.Call JMJDWX Steel if you need specific sizes or grain direction.
