has higher strength and hardenability. The 42CrMo4 alloy material also
has high fatigue strength and good low-temperature impact toughness. The
temper brittleness is not obvious.
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
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
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.
I have tried several methods of cutting up wheels for melting and the method show I have found works best.
Special thin aluminium cutting discs in an angle grinder wear out too quickly. The Evolution saw runs at a slower speed that a woodworking saw and the Evolution blade cuts the metal OK but the fine teeth clog easily and can break off when cleaned out. The blade shown has fewer teeth so there is no room for metal to clog them.
