George Metals is well-known for their dedication to quality and accuracy, and they work with a range of industries, including petrochemical, power generation, aerospace, and marine. Their SS 321 rectangular bars are designed with titanium stabilisation, which offers remarkable strength at high temperatures and resistance to intergranular corrosion. George Metals provides customised solutions that satisfy global standards with an emphasis on quality, dependability, and client satisfaction. They are the go-to source for stainless steel products in both domestic and international markets because of their large inventory, affordable prices, and quick delivery.
Austenitic stainless steel stabilised by titanium, Stainless Steel 321 Rectangular Bars are made up of 17–19% Chromium, 9–12% Nickel, and trace amounts of manganese, silicon, and titanium (≥5×C content). At high temperatures, this alloy provides exceptional resistance to oxidation and intergranular corrosion. Its elongation is 40%, its yield strength is 205 MPa, and its tensile strength is approximately 515 MPa. Even at high temperatures (up to 900°C), SS 321 maintains its good mechanical qualities. It is appropriate for prolonged heat exposure in demanding conditions due to its resistance to carbide precipitation.

Applications requiring high temperatures and corrosive conditions are best suited for stainless steel 321 rectangular bars. Heat exchangers, exhaust manifolds, furnace parts, and thermal processing equipment all make extensive use of them. The alloy is appropriate for use in refinery equipment, chemical processing vessels, and aircraft engine parts due to its resistance to oxidation and intergranular corrosion. Additionally, SS 321 is preferred in the food processing, pharmaceutical, and power generation sectors where durability and hygienic conditions are critical. It is a reliable option for both structural and pressure-based applications due to its exceptional weldability and formability, which enable it to be fabricated into intricate shapes while maintaining strength.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
