309S Stainless Steel Pipe
Guanyu Tube is specialized manufacturer of ASTM A213 ASME SA 213 TP 309S Stainless Steel Tube, EN 10216-5 1.4833 Stainless Steel Tubing 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.

TP309S Stainless Steel Tubes Properties and Character

309S Stainless Steel Tube 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 temperature. 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 is used often for higher temperature applications. While its oxidation resistance surpasses that of alloy 310, its resistance to corrosion is equivalent to that of alloy 310. Alloy 309 is highly weldable and cold formable, although it does require stronger forming machines and continuously increasing pressure. Typical machining methods are used for stainless steel grade 309, but it is tougher and does tend to harden more quickly. Like 310 Stainless Steel, 309S Stainless Steel has a high chromium and nickel content which grants excellent resistance to aqueous corrosion.

309S Stainless Steel Pipe manufacturer according to ASTM A213 and ASTM A312 ASTM A269 specifications.

TP309S 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.
