6.      Processing of 4130 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 4130 steel bar and pre machining 4130 steel bar as following:

1)      Heat treatment of 4130 steel

Oil quenching 4130 steel / 4130 normalizing steel / pre hardened 4130 steel / annealing 4130 steel / stress relieving 4130 steel / 4130 qt steel / flame hardening 4130 steel / 4130 steel induction hardening / case hardening 4130 steel / aisi 4130 oil quenched / austempering 4130 steel / 4130 steel water quenched / nitriding 4130 steel /  milling 4130 steel

After heat treatment, 4130 steel bar can get better heat treated 4130 steel properties, for example:

4130 steel quenched and tempered properties:

Yield strength of 4130 steel: 930MPa min

Tensile strength of 4130 steel: 1080MPa min

Elongation of 4130 steel: 12% min

Reduction area of 4130 steel: 50% min

Rockwell hardness of 4130 steel: 32HRC min

Brinell hardness of annealed 4130 steel: 217HB max

Vickers hardness of 4130 steel: We can also guarantee the Vickers hardness based on your special requirements.

2)      Machining 4130 steel:

knurling 4130 steel / tapping 4130 steel / grinding 4130 steel / turning 4130 steel / threading 4130 steel / cutting 4130 steel / drilling 4130 steel / forging 4130 steel / laser cutting 4130 steel / reaming 4130 steel / stick welding rod for 4130 steel /  bending 4130 steel / brazing 4130 steel / straightening 4130 steel / tg&p 4130 steel / polishing 4130 steel / cold drawing 4130 steel

     After the machining, 4130 steel can get precision size, various surface, better roughness, straightness etc. 4130 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.
