about Cold Drawn Steel Bar
Cold drawn steel bar is made from hot rolled steel bars or wire rod. Depend on the shape of the
mould,cold drawn steel bar can can be classified as cold drawn steel round bar,square bar,hexagonal
bar, flat bar and other shapes of steel bar or profiles.By cold drawing, the dimensional tolerances,
straightness and surface roughness of the bars will be improved. In the meanwhile, the mechanical
properties will be enhanced, too.
4130 cold drawn steel bar we supply includes following advantages
1.Precision size tolerance(h8, h9,h10, h11)
2.Good roundness
3.Good straightenss(0.2mm/m, 0.5mm/m, 1mm/m, 2mm/m)
4.Suitable sued mechanical properties (We can do heat treated according to final usage)
5.Good roughness to bright surface ( 0.4um, 0.6um, 0.8um)
6.More processing (Straightening, polishing, grinding)
7.Machinability is improved leading to a better tool life
8.No brittle, UT testing
9.Professional technical service
10.Competitive price
11.Fast delivery
