Stainless Steel 321 Square Bars and Rods are a type of austenitic stainless steel primarily made up of chromium and nickel, with titanium included to stabilize the structure. This addition of titanium helps prevent carbide precipitation, which boosts resistance to intergranular corrosion, especially after welding or exposure to high temperatures. In terms of mechanical properties, Stainless Steel 321 Square Bars and Rods provide good tensile strength, excellent ductility, and high toughness. They maintain their structural integrity even at elevated temperatures, making them ideal for challenging thermal and mechanical service conditions.

Stainless Steel 321 Square Bars are available in a range of sizes, typically from ¼" to 12" in width. Common finishes include mill finish, polished, and cold drawn.
Yes, Stainless Steel 321 Square Rods can be welded using most standard welding techniques. However, post-weld heat treatment may be required to maintain its properties and prevent sensitization.
Stainless Steel 321 Square Bars are generally non-magnetic in their annealed condition. However, they may exhibit slight magnetic properties if cold-worked.
Stainless Steel 321 Square Bars and Rods find extensive use in applications that demand resistance to heat, oxidation, and corrosion. You’ll commonly see them in exhaust manifolds, heat exchangers, furnace components, and expansion joints. These materials are widely utilized across industries such as chemical processing, petrochemical, oil and gas, aerospace, and power generation. Thanks to their excellent weldability and resistance to thermal fatigue, Stainless Steel 321 Square Bars and Rods are also perfect for pressure vessels and piping systems.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
