scm440 42CrMo4 4140 quenched and tempered steel tube
scm440 42CrMo4 4140 Quenched and Tempered Steel Pipe is used extensively in applications for automotive industry, Hydraulic, Mining and oil and gas drilling industry. Quenched and Tempered Steel Tubes include Qt Steel Tubes and Q&T drilling hollow steel bars. 42CrMo4 steel pipe has higher strength than 4130 pipe.
42CrMo4 Q&T steel tube we supply includes following advantages:
^ Consistent mechanical properties
^ Even thickness on the whole bars
^ Deep mechanical properties
^ 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.
