18crmo4 steel round bar
18crmo4 steel grade is one kind of low carbon Chromium Molybdenum steel material which is usually used to produce 18crmo4 steel joint, 18crmo4 steel nut, 18crmo4 steel screws, 18crmo4 steel shaft, steel stud, 18crmo4 steel flanges and valves etc. SCM420h steel material is in US standard as aisi 4120, sae 4120 and astm 4120. 18crmo4 steel grade equivalent materials includes aisi 4120h, sae 4120h, astm 4120h, 18crmo4, SCM420 etc. Except 18crmo4 steel material, there is also 18crmo4 steel material. The difference of 18crmo4 steel and 18crmo4h steel is that 18crmo4 steel is one kind of gear steel which is popular to be used to produce gears and shafts in cars, motors and parts needed strength and cutting features.

6. Processing of 18crmo4 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 18crmo4 steel bar and pre machining 18crmo4 steel bar as following:
1) Heat treatment of 18crmo4 steel
Oil quenching 18crmo4 steel / 18crmo4 normalizing steel / pre hardened18crmo4 steel / annealing 18crmo4 steel / stress relieving 18crmo4 steel / 18crmo4 qt steel / flame hardening 18crmo4 steel / 18crmo4 steel induction hardening / case hardening 18crmo4 steel / 18crmo4 oil quenched / austempering 18crmo4 steel / 18crmo4 steel water quenched / nitriding 18crmo4 steel / milling 18crmo4 steel
After heat treatment, 18crmo4 steel bar can get better heat treated 18crmo4 steel properties, for example:
18crmo4 steel quenched and tempered properties:
Yield strength of 18crmo4 steel: 685MPa min
Tensile strength of 18crmo4 steel: 885MPa min
Elongation of 18crmo4 steel: 12% min
