About Chilly Drawn Metal Bar
Chilly drawn steel bar is produced from hot rolled steel bars or wire rod. Rely on the form of the
mould,cold drawn steel bar can can be categorised as cold drawn steel round bar,sq. bar,hexagonal
bar, flat bar and other designs of  steel bar or profiles.By cold drawing, the dimensional tolerances,
straightness and surface area roughness of the bars will be improved. In the meanwhile, the mechanical
houses will be enhanced, as well.

SAE4140 steel round bar is a Chromium-Molybdenum by means of-hardening metal of medium
harden-capacity. It is a common purpose large-tensile metal with medium energy stage and good
impact houses.
SAE 4140 cold drawn metal bar we source consists of adhering to rewards:
-Consistent Mechanical Properties
-Even hardness on the entire bars/Harder and Improved power
-No brittle, UT screening/Precision measurement tolerance/Good straightness
-Great Roughness/Expert specialized provider/Competitive price/Rapidly delivery
