321 material:
Design Features:The key feature of 321 stainless is its resistance to intergranular corrosion.It employs titanium as a stabilizing element against chromium carbide formation.This alloy also exhibits strength characterics superior to those of 304 stainless.

Applications: Jet engine parts,furnace heat treated parts,expansion joints,turbo superchargers,oil refiners,exhaust manifolds and high temperature chemical production equipment.

Machinability:Slightly tougher than 304 stainless,this material will produce the same tough stringy chips.The use of slow speeds and constant positive feeds will minimize this alloy's tendency to work harden.

Hot working:Working temperature of 2100-2300 F(1149-1260 C) are recommended for forging,upsetting and other hot work process.Do not work this alloy at temperature below 1700 F(927 C).Material must be water quenched or fully annealed after working to reattain maximum corrosion resistance.

Cold working:Although this material requires higher initial forces than 304 stainless,it is quite tough and ductile and can be readily stamped,blanked,spun and drawn.

Annealing:1800-2000 F(928-1093 C),air cool.This procedure will result in maximum ductility.For maximum corrosion resistance,see the note on stabilizing anneal under corrosion.

Hardening:This alloy does not harden by heat treating.Elevated properties may only be obtained through cold reduction.
