Product Description

SS440 A36 S20C S45C 1020 1045 ST37 1018 Cold Drawn Round Steel Bar 
Cold Drawn Steel Round Bar, Square Bar, Hexagonal Bars with good bright surface and close tolerance. 

 

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.

1.Cold Drawn Steel Bar Processing:  EAF + LF + VD + CONCASTING BILLETS + HOT ROLLED + SHOT BLASTING +(ANNEALING) + COLD DRAWN + OILING + BUNDLING + BOTH ENDS CUTTING+ PACKING + MARKING

2.Application: hardware tools, auto parts, standard parts, fasteners common shaft, machinery manufacturing, light industry, hardware, bicycles, cars, motorcycles, textile machinery, transformers and other machinery industry

6.Advantages of cold drawn steel bar:
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.
