321, 321H, S32100, S32109, SAE 30321, B8T, B8TA, 18-8, Cr-Ni, AUSTENITIC STAINLESS STEEL (TITANIUM STABILIZED)

Description

321 is a non-hardenable, low carbon austenitic chromium-nickel steel which is particularly adaptable for parts fabricated by welding without post weld annealing for use at temperatures between 800 and 1500°F. This grade is non magnetic in annealed condition but slightly magnetic when cold worked.

Similar to Type 304 except Ti content helps prevent chromium carbide precipitation resulting from welding or elevated temperatures. Stabilized at annealing temperatures between 950-1010°C (1750-1850°F). Resists scaling and vibration fatigue.

Applications

Applications include aircraft exhaust stacks and manifolds, chemical processing equipment, weld equipment, jet engine parts.
