Renine Metalloys is a known supplier and manufacturer of SS 321 / 321H Pipes and Tubes, which cannot be hardened by thermal treatment. Gas shielded welding in Stainless Steel 321 Pipes has resulted in the best creep properties for welds. Stainless Steel 321 Tubes may be susceptible to chloride stress cracking, and has excellent weldability in field. 321 Stainless Steel Pipes can be easily welded and processed by standard shop fabrication practices. The high sulfur content of 321 Stainless Steel Tubes also has a detrimental impact on hot workability. Working temperatures of 2100 Degree F – 2300 Degree F (1149 Degree C – 1260 Degree C) are recommended in SS 321 Pipes for forging, upsetting and other hot working processes. Stainless Steel 321H Pipes is non-magnetic in the annealed condition and can be hardened only by cold working.

SS 321/321H Pipes & Tubes
Stainless Steel 321/321H Pipes & Tubes

Stainless Steel 321H Tubes has good low temperature toughness and comparable corrosion resistance and machinability to Type 304. Low carbon grades such as 321H Stainless Steel Pipes have insufficient carbon to deplete the chromium content generally throughout the structure. 321H Stainless Steel Tubes is often used for Expansion joints, Aircraft piston engine manifolds and exhaust stacks. This particular SS 321H Pipes is generally considered to have comparable weldability to Types 304 and 304L. Meanwhile, these SS 321H Tubes has extensive use in aircraft parts, such as exhaust systems where operating temperatures are higher than 800 Degree F
