Product Description

SAE 1008 1010 1018 1020 1045 S20C S45C SCM440 4140 B7 Cold Drawn Round Steel Bars

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
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.
