China manufacturer of cold drawn steel bars, types with cold drawn steel round bar, cold drawn steel square bar, cold drawn steel hexagonal bars , cold drawn steel special section according to drawn.
1.Cold Drawn Steel Bar Processing: EAF + LF + VD + CONCASTING BILLETS + HOT ROLLED + SHOT BLASTING +(ANNEALING) + COLD DRAWN + OILING + BUNDLING + BOTH ENDS CUTTING+ PACKING + MARKING
2.Application of cold drawn steel bars: hardware tools, auto parts, standard parts, fasteners common shaft, machinery manufacturing, light industry, hardware, bicycles, cars, motorcycles, textile machinery, transformers and other machinery industry
3.Advantages of cold drawn processing:
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.
