Product Description

Cold Drawn Steel Round Square Hexagonal Bar S45c C45 1045 CK45
Cold Drawn Steel Round Bar
Cold Drawn Steel Square Bar
Cold Drawn Steel Hexagonal Bar
Speical Steel Profile As Per Drawing



All bars are cleaned by shot blasting before drawing, then pulled through a carbide die, straightened, saw cut to length, oiled, and shipped.  Cold drawing results in a product with higher tensile and yield strength, smoother surface finish, and a closer size tolerance.

10.Advantages of 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.
