Dhruv Metals, a prominent manufacturer and supplier located in Hyderabad, India, specializes in top-notch Stainless Steel 440C Round Bars and Rods. These products are celebrated for their remarkable hardness, wear resistance, and impressive strength. Each round bar and rod is precision-engineered and heat-treated to ensure they deliver outstanding mechanical properties, making them perfect for high-performance applications across various industries. Dhruv Metals is committed to meeting rigorous international standards, establishing itself as a reliable source for toolmaking, bearing components, and other essential parts where durability and reliability are crucial.
The Stainless Steel 440C Round Bars and Rods are crafted from a high-carbon martensitic stainless steel that contains about 16–18% chromium and 0.95–1.20% carbon, along with trace amounts of manganese, molybdenum, and silicon. This particular grade can be heat-treated to reach a hardness of 58–60 HRC, which provides exceptional wear resistance and strength. Its mechanical properties include a tensile strength of up to 760 MPa and a yield strength of around 450 MPa, along with moderate corrosion resistance when hardened. These characteristics make 440C an excellent choice for applications that demand both hardness and dimensional stability under stress.

Yes, Stainless Steel 440C Round Bars/Rods can be used in cryogenic applications. Their high hardness and strength remain effective at low temperatures, making them suitable for use in cryogenic environments.
Yes, Stainless Steel 440C Round Bars/Rods require regular inspection to ensure their structural integrity, especially in high-stress applications, to detect any signs of wear, corrosion, or cracks over time.
Yes, Stainless Steel 431 Round Bars/Rods can be welded, although preheating and post-weld heat treatment are recommended to prevent cracking and maintain the material's mechanical properties.
Stainless Steel 440C Round Bars and Rods find extensive use in industries like aerospace, defense, medical, and manufacturing. They are often utilized to create bearings, valves, cutting tools, surgical instruments, pump components, and high-strength shafts. In scenarios involving repeated friction, pressure, or impact, 440C truly shines due to its ability to maintain hardness and resist wear. While it does offer moderate corrosion resistance, it is especially prized in environments where mechanical performance is paramount. Its machinability and high hardness after heat treatment make it a go-to material for precision-engineered, high-load applications.
