1020 Carbon Steel Round Bars Supplier in India
Nippon Alloys Inc is the trusted 1020 Carbon Steel Round Bars manufacturer, offering high-performance medium-low carbon steel bars designed for consistent strength and ease of processing. These round bars exhibit excellent ductility, machinability, and weldability, making them a preferred choice for automotive, mechanical, and construction applications. With a lower carbon content, 1020 steel bars are ideal for components that require surface hardening and better formability. Their smooth finish and dimensional accuracy enhance their use in fasteners, shafts, and general fabrication projects where reliable strength is essential. We are the best 1020 Carbon Steel Round Bars suppliers in India, supplying cold-drawn and hot-rolled bars in various lengths, diameters, and specifications. Our round bars are tested for surface quality, mechanical performance, and dimensional tolerance to meet industry standards like ASTM and AISI. These bars are commonly used in light-duty mechanical parts, axles, and gear components. We offer tailored cutting and finishing services along with efficient packaging and delivery options. With a strong supply network and competitive pricing, we support customers across sectors including manufacturing, oil & gas, agriculture, and machinery.

Type of Sub-products
Cold Drawn 1020 Carbon Steel Round Bar Cold Drawn 1020 Carbon Steel Round Bar
Cold drawn 1020 carbon steel round bars are manufactured by pulling the steel through dies at room temperature, which improves dimensional accuracy and surface finish. These bars offer increased strength and hardness, making them ideal for manufacturing shafts, pins, and other precision parts.
Hot Rolled 1020 Carbon Steel Round Bar Hot Rolled 1020 Carbon Steel Round Bar
Hot rolled 1020 carbon steel round bars are produced at elevated temperatures, resulting in a rough surface finish and slightly less precise dimensions. They are cost-effective and commonly used in general structural applications where exact tolerances are not critical. Their strength makes them suitable for fabrication and construction purposes.
