4.Tolerance of cold drawn steel bars: h9 h10 or as required
5.MOQ of our cold drawn steel bars: 2tons per size
6.Straightness of cold drawn steel bars: max 0.8mm/m
7.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
8.Why chooce cold drawn steel bars:
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.
