Semih Metals, located in Istanbul, Turkey, stands out as a top manufacturer and supplier of Stainless Steel 440C Square Bars and Rods. They offer high-quality stainless steel products designed for maximum hardness, wear resistance, and strength. Crafted with precision and adhering to strict quality standards, these bars and rods provide outstanding mechanical performance and durability. Semih Metals guarantees excellent dimensional accuracy and reliability, making their Stainless Steel 440C Square Bars and Rods perfect for industries like tooling, automotive, aerospace, and defense, where high-performance stainless steel components are essential for critical applications.
The composition of Stainless Steel 440C Square Bars and Rods primarily includes iron, chromium (16–18%), and carbon (up to 1.2%), along with trace amounts of manganese, silicon, and molybdenum. As the highest carbon-content grade in the 400 series, 440C offers exceptional hardness, wear resistance, and edge retention when heat treated. Mechanically, it showcases very high tensile strength, compressive strength, and impressive toughness, although its corrosion resistance is moderate compared to lower-carbon stainless steels. This blend of high hardness and mechanical durability makes 440C an excellent choice for high-stress, precision applications.

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.
You’ll find Stainless Steel 440C Square Bars and Rods widely utilized in industries where hardness, wear resistance, and strength are paramount. Common applications include bearings, valve components, industrial blades, molds, cutting tools, and precision mechanical parts. They’re also used in aerospace, automotive, and defense sectors for components that endure high friction and heavy loads. While their corrosion resistance is moderate, they perform admirably in dry and mildly corrosive environments. The remarkable hardness, toughness, and dimensional stability of Stainless Steel 440C Square Bars and Rods ensure they deliver long-lasting performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
