Latham Steel, located in Hamilton, New Zealand, stands out as a top manufacturer and supplier of Stainless Steel 321 Hex Bars and Rods. They pride themselves on delivering high-quality materials that are built to last, showcasing impressive durability, strength, and exceptional resistance to high-temperature corrosion. The Stainless Steel 321, which is stabilized with titanium, is a go-to choice for applications where intergranular corrosion resistance and thermal stability are crucial. Latham Steel guarantees that every hex bar and rod adheres to strict international standards, ensuring precise dimensions, consistent quality, and long-lasting performance across various industries, including chemical processing, petrochemical, aerospace, and power generation.
These Stainless Steel 321 Hex Bars and Rods are made up of about 17–19% chromium, 9–12% nickel, and a carefully controlled amount of titanium for stabilization. This specific composition helps prevent carbide precipitation during welding or when exposed to high temperatures, enhancing their resistance to intergranular corrosion. On the mechanical side, 321 hex bars and rods boast a tensile strength ranging from 515 to 750 MPa, a yield strength between 205 and 450 MPa, and good elongation, all while maintaining toughness and dimensional stability under thermal stress. Their hexagonal shape not only allows for excellent machinability but also ensures a secure fit in precision components.

SS 321 hex bars/rods are highly suitable for high-temperature applications due to their excellent resistance to oxidation and scaling, particularly in environments above 900°C. The addition of titanium stabilizes the material, preventing carbide precipitation, and enhancing its resistance to intergranular corrosion, making it ideal for aerospace and industrial applications.
SS 321 hex bars/rods are commonly used in industries requiring high-temperature resistance, such as aerospace, chemical processing, and power generation. Applications include exhaust systems, heat exchangers, furnace components, and reactors. Their resistance to corrosion, oxidation, and scaling makes them ideal for environments with elevated temperatures and aggressive conditions.
SS 321 hex bars/rods can be welded easily, but special care is needed to prevent carbide precipitation. Preheating and post-weld heat treatment are recommended to avoid weld embrittlement. Using titanium-stabilized filler metals helps maintain the alloy’s resistance to intergranular corrosion, ensuring weld integrity in high-temperature applications.
You’ll find Stainless Steel 321 Hex Bars and Rods commonly used in furnace components, heat exchangers, turbine parts, exhaust systems, and chemical processing equipment. Their unique blend of high-temperature resistance, corrosion protection, and structural integrity makes them perfect for demanding industrial settings. Engineers and manufacturers often choose 321 hex bars and rods for applications that require reliability, low maintenance, and consistent performance even in harsh operating conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
