Chuck Metals stands out as a trusted manufacturer and supplier of top-notch Stainless Steel 440C Square Bars and Rods in Singapore, Pulau Ujong. Renowned for its impressive hardness, outstanding wear resistance, and remarkable mechanical strength, Stainless Steel 440C is a high-carbon martensitic stainless steel that shines in demanding industrial settings. At Chuck Metals, we craft 440C square bars with meticulous attention to detail, ensuring precise dimensions, a smooth surface finish, and reliable metallurgical properties. These bars are built to excel under high-load and abrasive conditions, making them perfect for critical components in aerospace, tooling, surgical, and mechanical systems. Plus, their square shape boosts stability and machining efficiency for structural applications.
Stainless Steel 440C (UNS S44004) generally comprises 16–18% Chromium and 0.95–1.20% Carbon, along with small amounts of Manganese, Silicon, Molybdenum, and Phosphorus. This martensitic stainless steel can reach hardness levels of 58–60 HRC after heat treatment. It boasts a tensile strength of 760–1030 MPa and a yield strength of around 450 MPa. While 440C offers excellent hardness, wear resistance, and dimensional stability, its corrosion resistance is a bit lower compared to austenitic grades. The square bar shape simplifies machining and alignment in mechanical assemblies, especially where load-bearing and precision are crucial.
