42CrMo4 cold drawn Hexagonal Steel Bar
42CrMo4 steel is a Chromium-Molybdenum through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties.
Cold finished steel is cold drawn or cold rolled by hot rolled steel. It is typically produced as turned bars or cold drawn 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.
42CrMo4 cold drawn steel bar we supply includes following advantages:
Consistent mechanical properties
Deep mechanical properties (from surface to the center according to your requirement)
Even hardness on the whole bars/Tougher and Increased strength
No brittle, UT testing/Precision size tolerance/Good straightness
Good Roughness/Professional technical service/Competitive price/Fast delivery

Shandong Le Ren Special Steel CO., Ltd. owns three factories to produce all kinds of steel rod, steel bar and finished steel products. Among three factories, one is to produce steel bars such as annealed, normalized and quenched and tempered steel bar and pipe, cold drawn, peeled, ground and polished steel bar etc; one is to produce threaded or knurled steel rod and steel bar; another one is to do steel bar, steel rods or steel pipe machining.
In the tactories, we have complete and advanced production, inspection and testing facilities such as shot blasting machines, cold drawing machines,straightening machines, annealing furnace, quenching and tempering furnaces, threading machines, cnc machines, welding machines etc, and inspections and testing facilities to inspect dimension tolernaces, corner radius, length, straightness, surface roughness, mechanical properties, AKV, UT testing, Eddy testing and MPI testing etc. All of these, including more than twenty years production and exporting experiences, we can supply you good quality products and services.
Our factory is equipped with complete inspection and testing facilities to inspect steel bar dimension tolernaces, corner radius, length, straightness, surface roughness, mechanical properties, AKV, UT testing, Eddy testing and MPI testing etc.
Most of our steel bar are cold drawn, peeled, ground and polished steel bar which require good surface and straightness. So steel bar packing is very important to keep good quality. We use several kinds of steel bar packing according to your technical requirements.
