Which is better, 30CrMo seamless pipe or 20MnV steel pipe?

The mechanical properties of 30CrMo seamless pipe are as follows:
The tensile strength is 930 MPa, the yield strength is 785 MPa, the elongation after fracture is 12%, and the impact absorption energy is 63J.

30CrMo seamless pipe has high strength, high toughness, good high temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance when the temperature is lower than 500℃.

The mechanical properties of 20MnV steel pipe are as follows:
The tensile strength is 785 MPa, the yield strength is 590 MPa, the elongation after fracture is 10%, the reduction of area is 40%, and the impact absorption energy is 55J.

20MnV steel pipe has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, it can be directly quenched without secondary quenching to improve the core structure. The weldability is good, but there is temper brittleness at 300-360℃ during heat treatment.

It can be seen from the above that, compared with 20MnV steel pipe, the performance of 30CrMo seamless pipe is better.
