Isis Metals is a well-respected manufacturer and supplier of Stainless Steel 440C Square Bars and Rods, proudly based in Manila, Philippines. We specialize in crafting high-performance stainless steel products that are built to last, offering strength, precision, and durability. Our Stainless Steel 440C Square Bars and Rods are made from top-quality raw materials and cutting-edge technology, ensuring they boast superior hardness, wear resistance, and corrosion protection. Renowned for their outstanding mechanical properties and precise dimensions, these bars and rods are perfect for applications that require exceptional strength and durability. At Isis Metals, we provide Stainless Steel 440C Square Bars and Rods that meet international standards, guaranteeing reliable performance in various industrial, mechanical, and engineering settings.
Stainless Steel 440C Square Bars and Rods are martensitic stainless steels that consist of chromium (16–18%), carbon (0.95–1.20%), manganese (up to 1.00%), silicon (up to 1.00%), along with trace elements like molybdenum, sulfur, and phosphorus. These bars and rods showcase impressive tensile strength ranging from 760 to 960 MPa, a yield strength of about 450 MPa, and an elongation of roughly 14%. They provide excellent hardness, wear resistance, and moderate corrosion resistance, especially after undergoing heat treatment. Stainless Steel 440C Square Bars and Rods maintain high mechanical strength and stability under stress, making them ideal for precision applications and those that bear heavy loads.

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 industries that demand exceptional hardness, wear resistance, and precise dimensions. They are perfect for applications such as bearings, valve components, shafts, pump parts, cutting tools, and knife blades. Their durability and resistance to corrosion make them suitable for sectors like aerospace, marine, petrochemical, and automotive. Additionally, these bars and rods are utilized in medical instruments, molds, dies, and mechanical components that operate under high friction or load conditions. Their excellent machinability further enhances their appeal in various applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
