High Strength ASTM A193 B7 Threaded Rod
astm a193 grade b7 threaded rod is produced by threads rolling machines from ASTM A193 Grade B7 steel round bar which is usually 4140 Q&T steel round bar. After quenching and tempering, 4140 Alloy Steel Round Bar has higher and uniform mechanical properties which can improve the threaded rod wearability and makes it more tough.
Bolt performance grades are divided into more than 10 grades such as 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. Among them, the bolts of grade 8.8 and above are made of low-carbon alloy steel or medium-carbon steel and have been heat-treated (quenched, reconditioned, etc.). Fire), commonly known as high-strength bolts, the rest are commonly known as ordinary bolts. High-strength bolts are generally made of chrome-molybdenum alloy steel, and the US grades are 4140 and 4142.

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.
