The stub shaft forgings 42CrMo4 shaft forgings from us are of excellent quality and reasonable price.
Usually, these stub shaft forgings 42CrMo4 shaft forgings delivered in the state of rough turning and Q+T. We can also add the semi-fine turning or fine turning after Q+T according to customers’ request. These stub shaft forgings 42CrMo4 shaft forgings we provide have reasonable machining allowance. Customers’ machining cost will be greatly reduced and the subsequent machining time will be reduced greatly.
Before the steel cutting and hot forging processing, we will test the chemical composition of 42CrMo4 steel. All 42CrMo4 steel 100% complies with DIN EN ISO 683-2 standard.
After rough turning, we will conduct ultrasonic non-destructive testing on all stub shaft forgings 42CrMo4 shaft forgings. Ensure that all stub shaft forgings 42CrMo4 shaft forgings are of qualified quality.
The stub shaft forgings 42CrMo4 shaft forgings that pass the non-destructive testing will be Q+T according to the mechanical performance requirements. After quenching and tempering, we will conduct mechanical property tests on the samples to test tensile strength, yield strength, hardness, and impact energy.
The stub shaft forgings 42CrMo4 shaft forgings that fully meet the chemical composition requirements, mechanical property requirements and dimensional requirements will be handed over to our customers.
