Titanium in 321 stainless steel pipe exists as a stabilizing element, but it is also a heat-resistant steel grade, which is much better than 316L material at high temperatures. 321 stainless steel pipe has good wear resistance in organic and inorganic acids of different concentrations and temperatures, especially in oxidizing media, and is used to manufacture linings and conveying pipelines for wear-resistant acid containers and wear-resistant equipment.

321 Stainless Steel Pipe produced under specification ASTM A312 has been designed to resist inter-granular corrosion, especially in high temperature settings. 321 SS Piping has good toughness properties even at lower temperatures. 321 material is also called 1.4541 in DIN Germany standard and UNS S32100 Stainless Steel.
