Hemi Metals, located in Hamilton, New Zealand, is a reputable manufacturer and supplier of top-notch Stainless Steel 304L Hex Bars and Rods, perfect for industrial, commercial, and fabrication needs. These hex bars are crafted with meticulous attention to dimensional accuracy and consistent metallurgical properties, ensuring they meet rigorous international standards. Hemi Metals’ SS 304L hex bars boast impressive corrosion resistance, solid strength, and excellent weldability thanks to their low carbon content. They’re widely utilized across various industries, providing reliable performance, easy machinability, and long-lasting durability in both general-purpose and moderately corrosive environments.
Stainless Steel 304L Hex Bars and Rods are made up of about 18–20% chromium and 8–12% nickel, with a low carbon content of less than 0.03%. This lower carbon level helps prevent carbide precipitation during welding, which boosts corrosion resistance in welded structures. SS 304L hex bars deliver a tensile strength of roughly 485 MPa and a yield strength close to 170 MPa, along with outstanding ductility, toughness, and formability. They are non-magnetic when annealed, show good hardness stability, and ensure dependable mechanical performance in both regular and moderately elevated temperature settings.

SS 304L hex bars/rods are typically available in sizes ranging from 3.17mm to 350mm in diameter, with lengths of 2 to 7.5 meters. These bars come in various finishes, such as polished or cold-drawn. Custom sizes and specifications can also be produced upon request to meet specific needs.
Yes, SS 304L hex bars/rods are highly weldable and suitable for fabrication into complex shapes. Their low carbon content minimizes carbide precipitation during welding, reducing the risk of corrosion. This material's excellent ductility and toughness allow easy forming, machining, and fabrication, making it ideal for intricate designs and applications.
SS 304L has lower carbon content than standard 304, reducing carbide precipitation and enhancing corrosion resistance, particularly after welding. While slightly lower in strength compared to higher-carbon grades like 304 or 316, it maintains excellent toughness and durability. SS 316 offers superior corrosion resistance in chloride environments due to added molybdenum.
Stainless Steel 304L Hex Bars and Rods find their way into a variety of applications where corrosion resistance, weldability, and strength are essential. They are frequently used to manufacture fasteners, nuts, bolts, shafts, fittings, valves, and precision machine components. In industries like food, beverage, and pharmaceuticals, SS 304L hex bars are the go-to choice for hygienic and corrosion-resistant processing equipment. They also play a role in architectural fabrications, chemical storage systems, heat exchangers, and general engineering structures. With their clean surface finish, ease of fabrication, and resistance to oxidation, these hex bars ensure reliable performance both indoors and outdoors.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
