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
- Exhaust manifolds.
