Product Description

309S Stainless Steel Pipe Technical Data

309S Stainless Steel Tubing is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high temperature strength and creep resistance.  The lower nickel content of SX309 improves resistance to sulphur attack at high temperatures.  It is tough and ductile, and can be readily fabricated and machined. 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.

309S Stainless Steel Pipe manufacturer according to JIS G3459 specifications.

309S Stainless Steel Tubing Applications
309 / 309S is used exclusively for its high temperature oxidation resistance.  It is common for SX 309, 310 and 321 to be used in the same piece of equipment in the various temperature regions.
