Tensile requirement of 42CrMo4 steel

Tensile requirement of 42CrMo4 steel

DIN 42CrMo4 steel is popular steel material. It could be supplied as rolled, annealed or Q+T condition. Its material number is 1.7225. But What is 42CrMo4 Tensile Strength generally?
To achieve high tensile strength, 42CrMo4 could be (quenching and tempering) Q+T heat treated.
The tensile requirement of 42CrMo4 steel according to EN 10083 standard is as following:
