AISI 321 contains titanium, which prevents carbide precipitation during welding and improves resistance to intergranular corrosion in high-temperature environments.

Is AISI 321 suitable for welding?

Yes, AISI 321 offers excellent weldability and retains mechanical properties after welding, unlike non-stabilized grades like AISI 304.

Do you offer third-party inspected AISI 321 stainless steel?

Yes, we provide MTCs with optional inspection from agencies like SGS, TUV, BV, along with full export documentation.
