Material Notes:
Crucible 321 is a non-hardenable, low carbon austenitic chromium-nickel steel which is particularly adaptable for parts fabricated by welding without postweld annealing for use at temperatures between 800 and 1500°F. This grade is non magnetic in annealed condition but slightly magnetic when cold worked.Information provided by Crucible Specialty Metals.Composition: Titanium content is 5xC minimum
