Chung Metal provides Stainless Steel 321 round bars and rods—an austenitic, titanium‑stabilized composition that can be used to withstand high heat and inhibit intergranular corrosion. Produced in Da Nang with rigorous quality procedures, our 321 rods comply with mechanical, metallurgical, and dimensional requirements. Chemical processing, aerospace, and heat‑treatment equipment industries use 321 bar stock for components exposed to cyclic heat. Shafts, structural members, and fasteners at high temperatures find use with our rods. Our 321 rods from Chung Metal have good weldability and stability and are relied upon in hostile thermal situations.
SS 321 has ~17–19% chromium, ~9–12% nickel, ~0.3% titanium, with moderate carbon (~0.04–0.10%), and small Mn, Si. It offers tensile strength ~620–750 MPa, yield strength ~275–380 MPa, elongation ~30–40%. It has good creep resistance to ~900 °F (≈480 °C), and excellent intergranular corrosion resistance due to titanium stabilization. Hardness is moderate. It maintains toughness and ductility under alternating temperature conditions, and is weldable using conventional methods.
