EN10083-3 50CrMo4 heat treatment

EN10083-3 50CrMo4 heat treatment

As to 50CrMo4 heat treatment, 50CrMo4 steel is usually done quenching and tempering treatment. According to EN10083-3 standard, 50CrMo4 steel is quenched in oil, and the quenching temperature is 820 - 870℃. And the tempering temperature is 540-660℃. After quenching and tempering, EN10083-3 50CrMo4 plate gets good properties and strength.

EN10083-3 50CrMo4 plate properties with 50CrMo4 heat treatment (quenching and tempering) :

8<t≤20 780 1000-1200 10
20<t≤60 700 900-1100 12
60<t≤100 650 850-1000 13
100<t≤160 550 800-950 13

50CrMo4 steel is ultra high strength alloy structural steel. It has high strength and toughness, good hardenability and no obvious temper brittleness. After 50CrMo4 heat treatment, i.e. quenching and tempering, 50CrMo4 steel has high fatigue limit and multiple impact resistance.
