scm420h steel round bar
SCM420h steel grade is one kind of low carbon Chromium Molybdenum steel material which is usually used to produce SCM420h steel joint, SCM420h steel nut, SCM420h steel screws, SCM420h steel shaft, steel stud, SCM420h steel flanges and valves etc. SCM420h steel material is in US standard as SCM420h, SCM420h and SCM420h. SCM420h steel grade equivalent materials includes aisi 4120h, sae 4120h, astm 4120h, 18CrMo4h, 20CrMoh etc. Except SCM420h steel material, there is also SCM420h steel material. The difference of SCM420 steel and SCM420h steel is that SCM420h 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.
Our company is a manufacturer of SCM420h alloy steel bar including SCM420h Alloy Steel Round Bar, SCM420h Alloy Steel Square Bar, SCM420h alloy steel flat bar, SCM420h alloy Square Steel Bar and SCM420h alloy Hexagonal Steel Bar.

6. Processing of 4120h 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 SCM420h steel bar and pre machining SCM420h steel bar as following:
1) Heat treatment of SCM420h steel
Oil quenching SCM420h steel / SCM420h normalizing steel / pre hardened SCM420h steel / annealing SCM420h steel / stress relieving SCM420h steel / SCM420h qt steel / flame hardening SCM420h steel / SCM420h steel induction hardening / case hardening SCM420h steel / aisi SCM420h oil quenched / austempering SCM420h steel / SCM420h steel water quenched / nitriding SCM420h steel / milling SCM420h steel
After heat treatment, SCM420h steel bar can get better heat treated SCM420h steel properties, for example:
SCM420h steel quenched and tempered properties:
Yield strength of SCM420h steel: 685MPa min
Tensile strength of SCM420h steel: 885MPa min
Elongation of SCM420h steel: 12% min
Reduction area of SCM420h steel: 50% min
Rockwell hardness of SCM420h steel: 32HRC max
Brinell hardness of annealed SCM420h steel: 197HB max
Vickers hardness of SCM420h steel hv: We can also guarantee the Vickers hardness based on your special requirements.
2) Machining SCM420h steel:
knurling SCM420h steel / tapping SCM420h steel / grinding SCM420h steel / turning SCM420h steel / threading SCM420h steel / cutting SCM420h steel / drilling SCM420h steel / forging SCM420h steel / laser cutting SCM420h steel / reaming SCM420h steel / stick welding rod for SCM420h steel / bending SCM420h steel / brazing SCM420h steel / straightening SCM420h steel / tg&p SCM420h steel / polishing SCM420h steel / cold drawing SCM420h steel
After the machining, SCM420h steel can get precision size, various surface, better roughness, straightness etc. SCM420h steel can be used for axe, pins, knives, gun barrels, gears, bolts, washers, hammer, sword etc.
