6. Processing of scm430 steel:
We are a factory to process all kinds of steel bars on surface, size and microstructure. With complete production and processing facilities, we can supply all kind of pre heat treated scm430 steel bar and pre machining scm430 steel bar as following:
1) Heat treatment of scm430 steel
Oil quenching scm430 steel / scm430 normalizing steel / pre hardened scm430 steel / annealing scm430 steel / stress relieving scm430 steel / scm430 qt steel / flame hardening scm430 steel / scm430 steel induction hardening / case hardening scm430 steel / scm430 oil quenched / austempering scm430 steel / scm430 steel water quenched / nitriding scm430 steel / milling scm430 steel
After heat treatment, scm430 steel bar can get better heat treated scm430 steel properties, for example:
scm430 steel quenched and tempered properties:
Yield strength of scm430 steel: 930MPa min
Tensile strength of scm430 steel: 1080MPa min
Elongation of scm430 steel: 12% min
Reduction area of scm430 steel: 50% min
Rockwell hardness of scm430 steel: 32HRC min
Brinell hardness of annealed scm430 steel: 217HB max
Vickers hardness of scm430 steel: We can also guarantee the Vickers hardness based on your special requirements.
2) Machining scm430 steel:
knurling scm430 steel / tapping scm430 steel / grinding scm430 steel / turning scm430 steel / threading scm430 steel / cutting scm430 steel / drilling scm430 steel / forging scm430 steel / laser cutting scm430 steel / reaming scm430 steel / stick welding rod for scm430 steel / bending scm430 steel / brazing scm430 steel / straightening scm430 steel / tg&p scm430 steel / polishing scm430 steel / cold drawing scm430 steel
After the machining, scm430 steel can get precision size, various surface, better roughness, straightness etc. scm430 steel can be used for axe, pins, knives, gun barrels, gears, bolts, washers, hammer, sword etc.
As a Chinese steel bar professional manufacturer and supplier of more than twenty years, with complete produce and processing facilities, advanced testing equipments and big stock of steel bar, we can supply 4130 steel bar with good quality, competitive price, short delivery time and personalized customization. We welcome old and new customers to inquire to us for technical questions and demands.
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.
