Hemi Metals, located in Hamilton, New Zealand, is a reliable manufacturer and supplier of high-quality Stainless Steel 410 Flat Bars, perfect for industrial applications that demand strength and wear resistance. SS 410 is a type of martensitic stainless steel celebrated for its impressive hardness, decent corrosion resistance, and robust mechanical properties. Crafted with precision in dimensions, a smooth finish, and strict metallurgical standards, these flat bars deliver dependable performance even in tough conditions. Hemi Metals caters to various industries, including automotive, oil & gas, power generation, chemical processing, and heavy engineering, where durability and strength are crucial.
Stainless Steel 410 is made up of about 11.5–13.5% chromium, with a controlled carbon content that boosts its hardness and strength. This unique blend offers moderate resistance to corrosion and responds exceptionally well to heat treatment. Typically, SS 410 flat bars have a tensile strength between 480–700 MPa in their untreated state, which increases significantly after hardening and tempering. The material is magnetic, exhibits good wear resistance, and maintains a fair level of ductility. Additionally, it boasts good machinability when annealed and reliable mechanical performance under heavy loads.
