Stainless Steel 440C Square Bars and Rods are a high-carbon martensitic stainless steel grade celebrated for their outstanding hardness, strength, and resistance to corrosion. Typically, their composition features 16–18% chromium, 0.95–1.20% carbon, along with trace amounts of manganese, silicon, and molybdenum. These bars and rods can undergo heat treatment to achieve peak hardness and wear resistance. In terms of mechanical properties, they boast a tensile strength of 700–900 MPa, a yield strength of around 450–650 MPa, and a hardness rating between 58–60 HRC. These characteristics make them perfect for applications that demand precision, durability, and wear resistance in moderately corrosive environments.

Yes, Stainless Steel 440C Square Bars are magnetic. This is because they are martensitic stainless steel, which contains a high amount of carbon, making them ferromagnetic.
Yes, Stainless Steel 440C square rods can be heat-treated to improve hardness and strength. The typical heat treatment process includes austenitizing, quenching, and tempering.
Stainless Steel 440C square bars offer excellent high-temperature strength and maintain their hardness and wear resistance in elevated temperatures. However, prolonged exposure may lead to some reduction in toughness and ductility.
Stainless Steel 440C Square Bars and Rods find extensive use in applications that require high hardness, wear resistance, and corrosion protection. They are frequently utilized in the production of bearings, knives, valves, cutting tools, and precision instruments. Their exceptional strength and durability render them ideal for aerospace components, automotive parts, and industrial machinery that face high stress. Additionally, they are employed in medical instruments, marine hardware, and tooling applications. With Starc Metals’ stainless steel 440C products, you can count on long-lasting performance and precision.
