Stainless steel 321 is an austenitic stainless steel that is particularly known for its excellent resistance to corrosion and high-temperature oxidation. It is stabilized with titanium, which helps prevent grain boundary carbide precipitation during welding and high-temperature service.
- Corrosion Resistance: Excellent resistance to a wide range of corrosive environments, including sulfuric and phosphoric acids.
- High-Temperature Stability: Maintains strength and oxidation resistance at elevated temperatures, making it suitable for applications in the aerospace and chemical processing industries.
- Weldability: Good weldability without requiring post-weld heat treatment.
