6.      Processing of 34CrMo4 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 34CrMo4 steel bar and pre machining 34CrMo4 steel bar as following:

1)      Heat treatment of 34CrMo4 steel

Oil quenching 34CrMo4 steel / 34CrMo4 normalizing steel / pre hardened 34CrMo4 steel / annealing 34CrMo4 steel / stress relieving 34CrMo4 steel / 34CrMo4 qt steel / flame hardening 34CrMo4 steel / 34CrMo4 steel induction hardening / case hardening 34CrMo4 steel / 34CrMo4 oil quenched / austempering 34CrMo4 steel / 34CrMo4 steel water quenched / nitriding 34CrMo4 steel /  milling 34CrMo4 steel

After heat treatment, 34CrMo4 steel bar can get better heat treated 34CrMo4 steel properties, for example:

IMG_20210125_154536

34CrMo4 steel quenched and tempered properties:

Yield strength of 34CrMo4 steel: 930MPa min

Tensile strength of 34CrMo4 steel: 1080MPa min

Elongation of 34CrMo4 steel: 12% min

Reduction area of 34CrMo4 steel: 50% min

Rockwell hardness of 34CrMo4 steel: 32HRC min

Brinell hardness of annealed 34CrMo4 steel: 217HB max

Vickers hardness of 34CrMo4 steel: We can also guarantee the Vickers hardness based on your special requirements.

2)      Machining 34CrMo4 steel:

knurling 34CrMo4 steel / tapping 34CrMo4 steel / grinding 34CrMo4 steel / turning 34CrMo4 steel / threading 34CrMo4 steel / cutting 34CrMo4 steel / drilling 34CrMo4 steel / forging 34CrMo4 steel / laser cutting v steel / reaming 34CrMo4 steel / stick welding rod for 34CrMo4 steel /  bending 34CrMo4 steel / brazing 34CrMo4 steel / straightening 34CrMo4 steel / tg&p 34CrMo4 steel / polishing 34CrMo4 steel / cold drawing 34CrMo4 steel / centerless ground bar / polished steel bar / peeled or turned steel bar / 

     After the machining, 34CrMo4 steel can get precision size, various surface, better roughness, straightness etc. 34CrMo4steel 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 34CrMo4 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.





Company Overview

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.
