Supply Grade of cold drawn steel bar
Cold drawn steel bar tolerance:h8,h9,h10,h11
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
