Product Description

42CrMoS4 Cold Drawn Steel Round Bar


42CrMoS4 is a kind of hardening steel similar to 42CrMo4 but with limited sulphur content 0.020%-0.035% general in quenched and tempered condition such as 42CrMoS4 cold drawn and Quenched And Tempered Steel Bar and Hexagonal Steel Bar.

 

Cold finished steel bar is cold drawn or cold rolled by Hot Rolled Steel Bar. It is typically produced as turned steel bars or Cold Drawn Steel bars. Cold Drawn Steel Bar is accomplished by cold drawing a bar through a mould. By cold drawing, the dimensional tolerances, the straightness and the surface roughness of the bars will be improved. In the meanwhile, the mechanical properties will be enhanced, too.


Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.
