4140 pre heat treated steel bar
4140 pre heat treated steel bar is 4140 steel bar after quenching and tempering before using, it can also be called as 4140 hardened steel bar or 4140 quenched & tempered steel bars, 4140 qt steel bar and 4140 ht steel bar. 4140 pre hardened steel bar has high hardness and good mechanical properties. We can produce 4140 pre heat treated steel bar with difference hardness mechanical properties according to customers different technical requirements. We can supply various 4140 pre heat treated steel bar such as 4140 tg&p steel bar, 4140 peeled & polished steel bar, 4140 cold drawn and QT steel bar etc.

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.
