Generally,the material of press brake die inlcuding T8 steel, T10 steel, 42CrMo,and Cr12MoV.
Cr12MoV is also good material.The using performance can be satisfied,the process performance is also good,but the price will be high.
42CrMo is a high strength alloy quenched and tempered steel with high strength and strong toughness.It can work ubder the temperature of-500℃.

It mainly requires high strength,high toughness,and good wear resistance.
