Chuck Metals is proud to be a top manufacturer and supplier of premium **Stainless Steel 440C Round Bars and Rods** in Singapore, Pulau Ujong. Known for their precision, durability, and outstanding performance, Chuck Metals offers high-carbon martensitic stainless steel bars that provide remarkable hardness and wear resistance. Stainless Steel 440C is a popular choice for demanding applications across aerospace, medical, automotive, and tooling industries. Chuck Metals guarantees that each round bar and rod adheres to strict quality standards, ensuring excellent surface finish, precise dimensions, and compatibility with heat treatment. These bars are perfect for components that face high loads, friction, and require tight tolerances.
Stainless Steel 440C (UNS S44004) generally contains 16–18% Chromium and 0.95–1.20% Carbon, along with trace amounts of Manganese, Silicon, Molybdenum, and Phosphorus. This martensitic alloy can reach a hardness of 58–60 HRC when heat-treated. It boasts a tensile strength of 760–1030 MPa and a yield strength of about 450 MPa. 440C is known for its excellent wear resistance, high strength, and moderate corrosion resistance, particularly when hardened and passivated. These round bars and rods are magnetic and can be machined in the annealed state, making them ideal for precision parts that demand durability and sharp tolerances.
