Product Description
SAE 1020 S20c Ss440 A36 Q235 1045 S45c C45 4140 En19 Scm440 40cr B742CrMo4 12L14 1215 1144 Cold Drawn Steel Round Bar Steel Bar
Cold drawn steel bar is made from special quality hot rolled steel bar. It is drawn through a die reducing the cross-sectional area of the bar and giving it a smooth surface.
  • Shapes: According to the shapes of the die, the finished product can get a round, hexagonal, square, flat and other cross section.
  • Advantage: Cold drawn bars have greater size accuracy, straightness and increased tensile and yield strength as well as improved machinability.
  • Further processing: In addition to standard cold drawn steel bars. It can also be polished or ground to get better surface.

1.Cold Drawn Steel Bar Processing: Production line: hot rolled bars/wire rods - (spheroidizing annealed for alloy steel/bearing steel) - pickling - cleaning - saponifing - cold drawn - (softening annealed for alloy steel/bearing steel) - cutting - bundling - packing - finished products
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 industry3.Capabilities of our fatcory
