321 Stainless Steel Tubing

321 stainless steel tubing

 

Kamal Steel is one of the distinguished stockiest and supplier of 321 Stainless Steel Tubing Suppliers where we offer the same at standard and customized sizes. ASTM A269 Seamless and Welded Austenitic SS 321 Tubing is readily welded by all common methods including submerged arc. Stainless Steel UNS S32100 Pipes is a heat resistant, titanium stabilized, an austenitic alloy that's commonly used for service in the 1000 – 1600Deg F temperature range. These SS DIN 1.4541 Welded Pipes and Tubes cannot be hardened by thermal treatment. SS 321 Seamless Tubing is similar to type 304 stainless but with a titanium addition of at least five times the carbon content. This titanium addition in Stainless Steel 321 Pipe reduces or prevents carbide precipitation during welding and in the 800–1500Deg F service conditions. SUS321 pipe is generally considered to have comparable weldability to 304 and 304L stainless with the main difference being the titanium addition which reduces or prevents carbide precipitation during welding. In order to provide optimum resistance to intergranular corrosion & to polythionic acid stress corrosion cracking in service temperatures at 1500 – 1650Deg F an air cool may be used in these AISI 321 Tubes. Buy ASTM A269 Seamless and Welded Austenitic SS 321 Tubing at reasonable cost from us.
