Cold Finish Stainless Round 321 Annealed

Part #: 12884

Stainless Steel Round Bar T-321 (1.5") contains increased titanium for improved strength and heat resistance, making it ideal for applications in temperatures up to 900°C. Stainless 321 round bar is a choice material in applications involving welding or sustained elevated temperature operations where re-annealing is not practical.
