● A carbon steel bar is a solid, elongated rod made from carbon steel—an alloy of iron and carbon, with minimal other elements. Classified by carbon content (low, medium, high), it varies in strength and ductility. ● Low-carbon bars (e.g., A36) are ductile and weldable, used in construction or fasteners. Medium-carbon types balance strength and toughness, ideal for machinery parts. High-carbon variants are hard and wear-resistant, suited for tools or springs. ● Available in shapes like round, square, or hexagonal, they come in various lengths and diameters. Widely used in manufacturing, construction, and engineering, these bars serve as raw material for fabrication, structural support, or component production.
