Product Description

Steel Grade 42crmo4+qt


    Our company is a manufacturer of 42CrMo4 alloy steel bar including 42CrMo4 Alloy Steel Round Bar, 42CrMo4 Alloy Steel Square Bar, 42CrMo4 alloy steel flat bar, 42CrMo4 alloy Square Steel Bar and 42CrMo4 alloy Hexagonal Steel Bar.

    42CrMo4 steel is a Chromium-Molybdenum through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties. Similar to C45 steel grade and 41Cr4 steel grade, they are all medium carbon steel.

    The difference between c45 steel material and 42CrMo4 steel material: 42CrMo4 steel has alloy element, it is kind of alloy steel bar. After heat treatment, 42CrMo4 steel material can get between mechanical properties.

    41Cr4 vs 42CrMo4:  42CrMo4 steel grade has better hardenability than 41Cr4 steel material. After quenching and tempering, 42CrMo4 can be whole pre hardened from core to side.

What is 42CrMo4 steel used for? 42CrMo4 steel bar is mainly used to produce high strength stud bolt, Threaded Rods, wind power bolt, pre-stressed anchor bolts, post stressed anchor bolt, Steel Tie Rod , tie bar, tension rod, Tension Bar etc. Shaft, axle shaft, crankshaft, shaft for sleeve, linear shaft, pump shaft, rotor shaft, sensor shaft, spline shaft, drive shaft, mandrel shaft, transmission shaft, screw rod etc. CNC machines, precision CNC machines etc. Ejector pins and Ejector rods.

6.      Processing of 42CrMo4 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 42CrMo4 steel bar and pre machining 42CrMo4 steel bar as following:

1)      Heat treatment of 42CrMo4 steel

Oil quenching 42CrMo4 steel / 42CrMo4 normalizing steel / pre hardened 42CrMo4 steel / annealing 42CrMo4 steel / stress relieving 42CrMo4 steel / 42CrMo4 qt steel / flame hardening 42CrMo4 steel / 42CrMo4 steel induction hardening / case hardening 42CrMo4 steel / aisi 42CrMo4 oil quenched / austempering 42CrMo4 steel / 42CrMo4 steel water quenched / nitriding 42CrMo4 steel /  milling 42CrMo4 steel

After heat treatment, 42CrMo4 steel bar can get better heat treated 42CrMo4 steel properties, for example:

42CrMo4 steel quenched and tempered properties:

Yield strength of 42CrMo4 steel: 930MPa min

Tensile strength of 42CrMo4 steel: 1080MPa min

Elongation of 42CrMo4 steel: 12% min

Reduction area of 42CrMo4 steel: 50% min

Rockwell hardness of 42CrMo4 steel: 32HRC min

Brinell hardness of annealed 42CrMo4 steel: 217HB max

Vickers hardness of 42CrMo4 steel: We can also guarantee the Vickers hardness based on your special requirements.

2)      Machining 42CrMo4 steel:

knurling 42CrMo4 steel / tapping 42CrMo4 steel / grinding 42CrMo4 steel / turning 42CrMo4 steel / threading 42CrMo4 steel / cutting 42CrMo4 steel / drilling 42CrMo4 steel / forging 42CrMo4 steel / laser cutting 42CrMo4 steel / reaming 42CrMo4 steel / stick welding rod for 42CrMo4 steel /  bending 42CrMo4 steel / brazing 42CrMo4 steel / straightening 42CrMo4 steel / tg&p 42CrMo4 steel / polishing 42CrMo4 steel / cold drawing 42CrMo4 steel

     After the machining, 42CrMo4 steel can get precision size, various surface, better roughness, straightness etc. 42CrMo4 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 42CrMo4 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.
