Ojas Pipes and Tubes, located in Kolkata, India, has made a name for itself as a top-notch manufacturer and supplier of high-quality Stainless Steel 420 Round Bars and Rods. These bars are meticulously crafted with durability and precision in mind, making them perfect for applications that demand high hardness, corrosion resistance, and a superior surface finish. Ojas is committed to ensuring that every product meets international standards, catering to industries like automotive, engineering, and manufacturing. Their SS 420 round bars come in a variety of diameters and lengths to meet specific needs, all while providing timely delivery, outstanding service, and competitive pricing both in India and on the global stage.
Stainless Steel 420 Round Bars and Rods are a type of martensitic stainless steel, containing about 12–14% chromium and a carbon content between 0.15–0.40%. This unique blend gives the alloy its impressive hardness and decent corrosion resistance after heat treatment. In terms of mechanical properties, you can expect a tensile strength ranging from 700–900 MPa, a yield strength of around 345 MPa, and an elongation of about 15%. The alloy is magnetic in both its annealed and hardened states and boasts excellent polishability, making it a great choice for precision-engineered components and tools that need to withstand wear while maintaining a smooth finish.
