Recommended annealing temperature for TP321 and 321 wrought stainless steel: 1040 °C (1900 °F); Minimum 1095 °C (2000 °F) for cold-worked 321H and 1050 °C (1095 °F) for hot-finished 321H. Stress-relieving treatments. For dimensional stability: Stress relieve at 205 to 480 °C (400 to 900 °F) and then slow cool (usual time, 4 h per inch ...
Stainless steel, also known as inox, corrosion-resistant steel ( CRES) and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum, carbon, nickel and nitrogen depending on its specific use and cost. Stainless steel's resistance to corrosion results ...
Oct 23, 2001 · Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized by Titanium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850 °C.

May 30, 2020 · AISI 321 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 321 is the AISI designation for this material. S32100 is the UNS number. Additionally, the British Standard (BS) designation is 321S12. The properties of AISI 321 stainless steel include two common variations.
Aug 15, 2023 · 321 stainless steel is a Ni-Cr-Ti austenitic stainless steel used in the manufacture of acid-resistant containers and wear-resistant equipment linings and pipelines. Japanese grade: SUS321. UK grade: 304S12, 321920. German grade: X10CrNiTi189. Also known as: Austenitic Stainless Steel.
Aug 18, 2023 · 4. 321 Stainless Steel. 321 stainless steel is a grade of stainless steel that is stabilized with titanium (0.4–0.7%). The addition of titanium provides improved weldability, resistance to sensitization, and intergranular corrosion at elevated temperatures.
The material 321 is an austenitic stainless steel with a titanium alloy, which stabilizes the metal against chromium carbide formation. For this reason, 321 can be welded with excellent resistance to intergranular corrosion. The material is also known by the designation EN 1.4541 and the material number X6CrNiTi18-10.
