Hemi Metals, located in Hamilton, New Zealand, is a reliable manufacturer and supplier of high-quality Stainless Steel 304L Flat Bars, perfect for a variety of industrial and architectural uses. These flat bars are crafted with meticulous attention to detail, ensuring precise dimensions, a smooth surface finish, and consistent metallurgical properties that align with international quality standards. Known for their outstanding corrosion resistance, excellent weldability, and dependable mechanical strength, Hemi Metals provides these flat bars to sectors like construction, food processing, chemical handling, fabrication, and heavy engineering, where durability, hygiene, and long-lasting performance are crucial.
Stainless Steel 304L Flat Bars are made up of about 18–20% chromium and 8–12% nickel, with a low carbon content of less than 0.03%. This low carbon level helps reduce the risk of carbide precipitation during welding, enhancing resistance to intergranular corrosion. Typically, SS 304L flat bars boast a tensile strength of around 485 MPa and a yield strength close to 170 MPa, along with impressive ductility and toughness. They are non-magnetic when annealed, maintain good hardness stability, and perform reliably in both normal and moderately elevated temperature conditions.
