EPG has set up a total set of high quality management method which is offered with advanced inspection and examination products. alloy Cast Steel (42CrMo4/one.7225 AISI 4140 SCM440)
one: 42crmo4 steel introduction
42crmo4 is a widespread chromium-molybdenum steel that normally utilised after quenched and tempered, with substantial depth, large hardenability. BS EN 42CrMo4 spherical steel has EPT overall performance than 34CrMo4 steel owing to the carbon and chromium content is greater. 42CrMo4 alloy metal has greater strength and hardenability. The 42CrMo4 alloy content also has high fatigue power and good lower-temperature influence toughness. The mood brittleness is not clear.

seven:FAQ of 42CrMo4 Steel:
a.Quenched and Tempered (Q T)
- Warmth 42CrMo4 metal little by little to 880 degC
- Soak at this temperature then quench in oil
- Temper as quickly as 42CrMo4 steel get to space temperature (20 degC)
- Heat uniformly to the appropriate temperature of 560 degC
- Withdraw the 42CrMo4 materials from the furnace and amazing in the air.
b. EPT of 42CrMo4 Alloy Metal
- Preheat 42CrMo4 engineering steel uniformly and slowly
- Improve the forging temperature up to 1150-1200 degC.
- AlwaEPTTkeep the forging temperature earlier mentioned at lEPT 850 degC
EPT steel 42CrMo4 has only minimal weldability. Preheating to two hundred-300 degC is strongly recommended the upper limit need to not be exceeded since of chance for deterioration of the chrome layer.
Alloy metal 42CrMo4 can be friction welded. Nevertheless, precautions are essential so as to restrict the development of undesirable microstructures in the welded zone.
d.Application of 42CrMo4 Alloy Steels
EN 42CrMo4 alloy metal is extensively used for engineering steel goal, these kinds of as: producing numerous types of EPTTry, auto, mining spare part, the EPTwheel of the engine, the driving EPT of supercharger, the connecting rob, the pinchock unEPTTthe large force, elements for EPTT practice programs, chilly formed fastener elements, shafts, EPTs, drill collars for the oil exploration, and so forth.
