    Q235 1045 S45c C45 Scm440 40cr B7 42CrMo4 1144 Cold Finished Cold Drawn Bright Steel Round Bar


    Cold drawn steel bar is made from special quality hot rolled steel bar. It is drawn through a die reducing the cross-sectional area of the bar and giving it a smooth surface.

    • Shapes: According to the shapes of the die, the finished product can get a round, hexagonal, square, flat and other cross section.
    • Advantage: Cold drawn bars have greater size accuracy, straightness and increased tensile and yield strength as well as improved machinability.
    • Further processing: In addition to standard cold drawn steel bars. It can also be polished or ground to get better surface.

    1.Cold Drawn Steel Bar Processing:

    Production line: hot rolled bars/wire rods - (spheroidizing annealed for alloy steel/bearing steel) - pickling - cleaning - saponifing - cold drawn - (softening annealed for alloy steel/bearing steel) - cutting - bundling - packing - finished products
    2.Application: hardware tools, auto parts, standard parts, fasteners common shaft, machinery manufacturing, light industry, hardware, bicycles, cars, motorcycles, textile machinery, transformers and other machinery industry.

    6.Advantages of cold drawn steel bar:
    1. It can remove the Size and Section which provides Tighter tolerances which Reduces machining losses.
    2. It can remove the Steel Surface Finish which Reduces surface machining & improves quality.
    3. It can remove the Straightness which Facilitates automatic bar feeding in CNC.
    4. It can increase the Mechanical Properties which Can reduce the need for hardening.
    5. It can improve the Machinability and Productivity which Enables higher machining feeds, high tool life, yield & speeds and improved machined finish.
