  • Alloy Steel Round Bar

    Alloy Steel Round Bar

    Alloy steel round bars are long, cylindrical steel bars made from carbon steel as the base material, with one or more alloying elements (such as chromium, nickel, molybdenum, manganese, silicon, etc.) added, and formed through smelting, rolling, or forging.

    Alloy steel round bars are important semi-finished raw materials in machinery manufacturing. By adjusting the composition and heat treatment process, they can achieve higher strength, toughness, wear resistance, or corrosion resistance than ordinary carbon steel. They are mainly used to manufacture mechanical parts that withstand high loads, impacts, or fatigue.

  • Cold Drawn Steel Round Bar bright round bars

    Cold Drawn Steel Round Bar

    Cold drawn steel round bars (also known as cold-drawn bright round bars) are circular cross-section steel bars made by forcefully drawing hot-rolled round steel bars through a die at room temperature, causing plastic deformation. The diameter is typically between Ф3mm and Ф100mm. Compared to hot-rolled round steel, their tensile strength and yield strength are significantly improved, with a high surface finish and no oxide scale, making them suitable for direct use in precision assembly.

  • Forged Steel Round Bars Forged Round Steel Bar

    Forged Steel Round Bar

    Forged steel round bars (commonly known as “forged round bars”) are circular cross-section steel bars made from steel ingots or rolled products. These are heated and then forged using processes such as free forging and die forging to apply impact or pressure, causing plastic deformation.

    Forged steel round bars typically have a smooth, unblemished surface (unlike rebar). Domestic production diameters range from Φ80-1500 mm, with custom lengths and subsequent heat treatment available. Compared to hot-rolled round bars of the same material, they exhibit significantly higher strength, toughness, and fatigue resistance, and can withstand greater impact loads and alternating stresses.

  • Hot Rolled Steel Round Bar

    Hot Rolled Steel Round Bar

    Hot rolled steel round bars are solid, long steel bars with a circular cross-section, formed by high-temperature rolling of steel billets. They are characterized by good hardenability, high hardness, and excellent wear resistance, but their dimensional accuracy and surface finish are lower than those of cold-drawn round bars.

  • Mild Steel Round Bar

    Mild Steel Round Bar

    Mild steel round bars are solid, long steel bars with a carbon content between 0.10% and 0.30% and a circular cross-section. They belong to the basic profiles of ordinary carbon structural steel.

    Mild steel round bars have a smooth, round surface without any texture. Their specifications are expressed in millimeters (mm) in diameter. They are manufactured in three ways: hot-rolled, cold-drawn, and forged. They are widely used in manufacturing parts that do not bear high stress but require high toughness.
