Dhruv Metals produces and supplies premium-grade Carbon Steel A105 Bars and Rods in Hyderabad, India, serving high-pressure piping and forged component industries. ASTM A105 sets the standard for carbon steel forgings used in pressure systems at both ambient and high temperatures. These bars and rods are known for their strength, ductility, and weldability, making them suitable for flanges, fittings, valves, and pressure vessels. Dhruv Metals ensures precise manufacturing and strict quality control, delivering products that meet ASTM, ASME, and other international standards. These A105 carbon steel bars come in various dimensions and finishes for customized industrial needs.
Carbon Steel A105 Bars/Rods contain carbon (up to 0.35%), manganese (0.6–1.05%), phosphorus (max 0.035%), sulfur (max 0.040%), and silicon (0.1–0.35%). They offer tensile strength between 485–655 MPa and a yield strength of at least 250 MPa, with elongation around 22%. These bars maintain excellent mechanical stability under pressure and at high temperatures. Their forgeability and toughness make them great for applications that need high impact resistance. A105 bars keep their structural integrity in both ambient and moderate-temperature environments, making them a reliable option for pressure-related components.
