Dhruv Metals, a top-notch manufacturer and supplier based in Hyderabad, India, specializes in high-performance Stainless Steel 440C Flat Bars. These bars are celebrated for their impressive hardness, wear resistance, and outstanding corrosion resistance when hardened. Crafted with precision and in line with global standards like ASTM A276 and A479, they’re perfect for applications that demand maximum mechanical strength and durability. With a high carbon content and a beautiful polish, 440C is the preferred choice for rigorous engineering, tooling, and industrial tasks. Dhruv Metals provides both standard and custom-sized 440C flat bars, ensuring tight tolerances and a remarkable surface finish.
Stainless Steel 440C Flat Bar is a high-carbon martensitic stainless steel that contains around 1.0–1.2% carbon, 16–18% chromium, along with trace amounts of manganese, silicon, and molybdenum. After heat treatment, it achieves impressive hardness (up to 60 HRC), with a tensile strength of about 760 MPa and a yield strength of around 450 MPa. 440C is known for its excellent wear resistance, decent corrosion resistance in mild environments, and high compressive strength. Its ability to achieve sharp edges and a polished surface makes it perfect for tools and precision parts that operate under significant mechanical stress and friction.
