Stainless Steel 321 (UNS S32100) is Titanium stabilized stainless steel which used for service in the 538 – 870°C temperature range because of its good mechanical properties. Alloy 321 stainless steel is stabilized against chromium carbide formation by the addition of titanium.

We at K. K. industries carries a wide range of 321 Stainless Steel inventory which comprises with pipe pipes, tubes, bars & rods, fasteners, fittings and flanges, slip-on, blind, weld-neck, lap joint, long welding neck, socket weld, elbows, tees, stub-ends, returns, caps, crosses, reducers, and pipe nipples etc. in different sizes, dimensions and specifications.

Alloy 321 stainless steel offers higher creep and stress rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns. Also, it provides higher resistance to intergranular corrosion in the heat affected zone (HAZ) and to polyphonic acid stress corrosion cracking. SS 321 stainless is readily welded by all common methods including submerged arc. 321 Stainless is good machinability and is readily fabricated. Contact us today for more information!
