Cold drawn steel bar is produced by Hot Rolled Steel Bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.
For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.
To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).
For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.
We have more advantages on producing cold drawn steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
