Ss440 A36 S20c S45c 1018 1045 4140 12L14 Steel Round Bars Cold Drawn Polished Steel
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
