Description

321 stainless steel contains a Titanium addition of at least five times the carbon content. This addition is made to reduce or eliminate chromium carbide precipitation - resulting from welding or exposure to high temperatures. Maximum stabilization is accomplished by annealing between 1750 degrees and 1850 degrees F.

Features
  • Contains a Titanium addition
  • Excellent resistance to oxidation and corrosion
