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.
