Product Description
SAE 1045 C45 S45C Cold Drawn Polished Bright Steel Round Bar Steel Bar
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.
