It displays good oxidation resistance at elevated temperatures has excellent resistance to intergranular corrosion and has excellent weldability. 321 cannot be hardened by thermal treatment, but strength and hardness can be increased substantially by cold working, with subsequent reduction in ductility. 321 Stainless Steel McMaster-CarrThe titanium content of 321 stainless steel preserves corrosion resistance around weld points. This material maintains its corrosion resistance in temperatures up to 1500° F.. Foil is often used as a heat-treating wrap in temperatures up to 2600° F. It is furnished with a crimping tool.. For technical drawings and 3-D models, click on a part number.
Heat Treatment Alloy 321 is non hardenable by heat treatment. It can only be hardened by cold working. Stress Relieving Heat to 1290°F (700°C) for 1 to 2 hours and then air cool. Welding Alloy 321 is weldable by common fusion and resistance methods. Use type 347 ller rod or electrodes. ATI 321/ATI 347/ATI 348The high resistance of the stabilized ATI 321, 347 and 348 stainless steels to sensitization and intergranular corrosion is illustrated by data for the ATI 321 alloy in the Copper-Copper Sulfate 16% Sulfuric Acid Test (ASTM A262, Practice E) below. Mill annealed samples were given a sensitizing heat treatment consisting of soaking at 1050°F Heat treating AISI 321 stainless steel - Material May 02, 2005 · For Type 321 Ti-stabilized stainless steel, section 15.2.3 of SA 480 states that a stabilization anneal may be used in case solution annealing temperature is higher than 1950°F and the steel is subsequently exposed to sensitizing conditions.
Aug 05, 2021 · Stainless Steel 321H Ferrule Fittings can be used in up to 10 % diluted solutions at elevated temperatures. Stainless Steel 321 Double Ferrule Fittings cannot be hardened by heat treatment, only by cold working, where it can also be easily welded and processed by standard shop fabrication practices.

May 16, 2013 · Heat treatment. Type 321 stainless steel cannot be hardened by heat treatment, in fact the only heat treat operation that is performed on it is that of annealing, at around 1950ºF (1065ºC,) followed by a water quench. This treatment gives maximum corrosion resistance for type 321 forgings.
