Starc Metals, based in Canberra, Australia, has built a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel products, including the high-performance Stainless Steel 440C Flat Bar. This flat bar is celebrated for its remarkable hardness, wear resistance, and corrosion resistance, making it perfect for tough industrial applications. At Starc Metals, advanced manufacturing techniques are paired with strict quality control to ensure that their flat bars meet international standards. With a commitment to precision, durability, and customer satisfaction, Starc Metals guarantees that each 440C Flat Bar delivers long-lasting performance, making it a go-to choice for industries throughout Australia and beyond.
The Stainless Steel 440C Flat Bars are high-carbon martensitic stainless steel, containing around 16–18% chromium, 0.95–1.2% carbon, along with small amounts of manganese, silicon, and molybdenum. This unique blend gives the material outstanding hardness, impressive wear resistance, and decent corrosion resistance. On the mechanical side, it boasts a tensile strength ranging from 760 to 1,000 MPa and a yield strength between 450 and 700 MPa, with hardness levels soaring up to 58–60 HRC after heat treatment. Thanks to its martensitic structure, it can be heat-treated to achieve exceptional strength and durability while still being easy to machine for precision applications.
