Semih Metals, located in Istanbul, Turkey, has built a solid reputation as a manufacturer and supplier of Stainless Steel 440C Rectangular Bars, delivering top-notch stainless steel solutions to industries around the globe. Crafted with precision and produced under rigorous quality control, these bars are celebrated for their outstanding hardness, wear resistance, and strength. Semih Metals guarantees durability, dimensional accuracy, and reliability in every product, making their stainless steel bars perfect for demanding applications. With a strong commitment to customer satisfaction, the company serves various sectors, including engineering, automotive, defense, and tooling, establishing itself as a trusted name in the stainless steel manufacturing arena.
Stainless Steel 440C Rectangular Bars are primarily made up of 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 and wear resistance when heat treated. Mechanically, it boasts very high tensile strength, compressive strength, and edge retention, although its corrosion resistance is moderate compared to lower carbon stainless steels. The blend of high hardness and mechanical durability makes 440C a go-to material for high-performance applications.
