Large bending machine mold

General with T8 or T10, T10A, and then some good 42CrMo material, it requires mainly high strength, high toughness and good wear resistance, the choice of cold work die steel.Cr12MoV is a very good material. The use of performance can meet, process performance is also good, the price will be higher.42CrMo is a higher strength alloy tempered steel, high strength, toughness is also good. Can work below 500 degrees.
