Description

SS 321 Sheet

SS 321 is a titanium-stabilized austenitic stainless steel, designed for applications involving continuous or intermittent high-temperature service. It offers strong resistance to intergranular corrosion and maintains mechanical strength after welding. This makes it suitable for components exposed to temperatures up to 900°C, such as thermal processing equipment, expansion joints, and exhaust systems.

This stainless-steel sheet provides good formability and weldability, along with stable performance in environments with thermal cycling. As a commonly used grade, the SS 321 sheet price in India may vary based on size, finish, and quantity.

Available in various thicknesses and surface finishes, SS 321 sheets meet industry standards and are supplied with quality certifications. As a leading stainless-steel supplier, we ensure consistency in mechanical properties and dimensional accuracy.
