Stainless Steel 321 is a titanium-stabilized austenitic alloy, primarily made up of 17–19% chromium, 9–12% nickel, and titanium content that is at least five times the carbon level. This unique composition boosts its resistance to intergranular corrosion after welding. The alloy boasts a minimum tensile strength of 515 MPa, yield strength of 205 MPa, elongation of 40%, and a maximum Brinell hardness of 217 HB. These characteristics make SS 321 rectangular bars perfect for high-temperature settings and applications that demand outstanding mechanical strength and oxidation resistance.

Yes, Stainless Steel 321 Rectangular Bars can be welded. They offer good weldability, particularly with proper preheat and post-weld heat treatment to prevent carbide precipitation.
Stainless Steel 321 Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent corrosion resistance. However, in harsh environments, extra coatings may be applied for enhanced protection.
Choose Stainless Steel 321 Rectangular Bars based on factors like strength, corrosion resistance, and temperature requirements of your application. Consider factors like weldability and environment exposure to ensure optimal performance.
Stainless Steel 321 Rectangular Bars find extensive use in industries that require high-temperature strength and oxidation resistance. In the aerospace sector, they’re utilized in exhaust systems, engine components, and heat shields. The chemical and petrochemical industries rely on them for reactors, heat exchangers, and piping systems that are exposed to elevated temperatures. In power generation, they play a crucial role in boiler equipment and turbine components. Additionally, SS 321 bars are well-suited for food processing, pharmaceutical manufacturing, and thermal processing equipment due to their corrosion resistance and structural integrity. Their durability and stability make them ideal for long-term industrial applications in challenging conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
