Description

Stainless Steel 321 Flat Bar

Stainless Steel 321 Flat Bar is a titanium-stabilized austenitic stainless steel designed for excellent resistance to intergranular corrosion and high-temperature oxidation. SS 321 is ideal for applications involving prolonged exposure to elevated temperatures (up to 900°C) and repeated thermal cycling. The addition of titanium improves structural stability during welding, making it a preferred material in thermal processing, aerospace, chemical, and exhaust systems.

Our flat bars are processed using precision engineering tools, industrial engineering services, and laser cutting machines to ensure superior strength and thermal resistance. As one of the established stainless-steel manufacturers in India, we maintain stringent quality control at every production stage.
