Our Quality key points of cold drawn steel

*The Min size tolerance we can produce is -0.02mm/+0mm.
* The Min  Straightness can be 0.2mm/m
* Surface very shinny and smoothly(Min roughness can be 0.4um)
* Control the mechanical properties  through annealing,normalized,quchening and tempering heat treatment
*Full inspection equirment,it can test size,rougness,UT level,properties,hardness etc
