What is 42CrMo4 ultrasonic examination equivalent steel material

The company always adheres to the 42CrMo4 ultrasonic examination principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great 42CrMo4 ultrasonic examination cause. Customers are welcome to visit our company at any time. We are always ready to support you.

Good weldabilityBecause of its low carbon content, low alloy element content, good plasticity and low hardenability, this material 42CrMo4 ultrasonic examination is not suitable to have quenching structure or crack at the weld. The cold and hot pressure processing performance is good. Because of its good plasticity and small deformation resistance, it is not easy to produce cracks after pressure processing. Good corrosion resistanceUnder various atmospheric conditions, it has higher corrosion resistance than carbon steel.
