Stainless Steel 321 Tubes

Other corrosive compounds in the hot atmosphere such as water and sulfur compounds in Stainless Steel 321H Welded Tubes will significantly reduce the maximum service temperature. Stainless Steel 321 EFW Tubes is readily welded by all common methods including submerged arc. Maximum stabilization in Stainless Steel 321H ERW Tubes is accomplished by annealing between 1750 ° F and 1850 ° F. Our Stainless Steel 321 Round Tubes is often used in woven or welded screens for high temperature mineral processing.

These Stainless Steel 321H Square Tubes is extremely resistant to inter-granular corrosion and has very good corrosion resistance in weld areas. Our Stainless Steel 321 Rectangular Tubes is also used in waste treatment including thermal oxidizers. Hardening rate of these Stainless Steel 321H Electropolish Tubes makes it less machinable than 410 stainless steel, but similar to Alloy 304.
