Although 42CrMo4 steel is more expensive than 41Cr4 steel, it is
more preferable in terms of material properties. EN 42CrMo4 alloy
engineering steel materials have been widely used in automotive
driving elements. Otai Steel is able to supply you prime quality of
42CrMo4 alloy steel materials with wide range.

5. Heat Treatment of 42CrMo4 Steels
Annealing of 42CrMo4 Steels
- Heat steel 42CrMo4 forged steel slowly and thoroughly to 800-850°C;
- Cool slowly in the furnace to the temperature 480°;
- Complete annealing the steel in the air.
Quenched and Tempered (Q+T)
- Heat 42CrMo4 steel slowly to 880°C;
- Soak at this temperature then quench in oil;
- Temper as soon as 42CrMo4 steel reach room temperature (20°C);
- Heat uniformly to the suitable temperature of 560°C;
- Withdraw the 42CrMo4 material from the furnace and cool in the air.
6. Forging of 42CrMo4 Alloy Steel
- Preheat 42CrMo4 engineering steel uniformly and slowly;
- Increase the forging temperature up to 1150-1200°C.
- Always keep the forging temperature above at least 850°C
7.Weldability
Engineering steel 42CrMo4 has only limited weldability. Preheating
to 200-300°C is strongly recommended; the upper limit should not be
exceeded because of risk for deterioration of the chrome layer.
Alloy steel 42CrMo4 can be friction welded. However, precautions
are necessary so as to limit the formation of undesirable
microstructures in the welded zone.
8.Application of 42CrMo4 Alloy Steels
EN 42CrMo4 alloy steel is widely used for engineering steel
purpose, such as: making various kinds of machinery, automobile,
mining spare part, the gearwheel of the engine, the driving gear of
supercharger, the connecting rob, the pinchock under the high
pressure, parts for power train applications, cold formed fastener
components, shafts, gears, drill collars for the oil exploration,
etc.
