309 Stainless Steel Pipe

309 Stainless Steel Pipe

309S/309 stainless steel pipe is typically used for elevated temperature applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304.309 is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high temperature strength and creep resistance.


309S is the low-carbon version of 309, and is recommended for applications where sensitisation, and subsequent corrosion by high temperature gases or condensates during shutdown may pose a problem.309 is manufactured to ASTM A 167 and 309S to ASTM A240 specifications.


Grade 309 stainless steel pipe is used often for higher temperature applications. Like 310 Stainless Steel, Grade 309 Stainless Steel has a high chromium and nickel content which grants excellent resistance to aqueous corrosion.
