321 Stainless Steel Bar

The key feature of 321 stainless is its resistance to inter-granular corrosion. It contains titanium, which stabilizes against chromium carbide formation. This material is also stronger than 304 stainless.

Applications

  • Jet engine parts
  • Heat treated parts
  • Expansion joints
  • Turbo superchargers
