When the finished products of 42CrMo4NiV electric steel forgings are ultrasonic tested , a batch of prod-ucts have been rejected due to internal inclusions .To reduce the loss , these forging materials are used as the consuma-ble electrode for the electroslag remelting , after being forged and rough machined , chemical composition analysis , high-magnification structure examination , ultrasonic examination and mechanical property test have been conducted , these test results meet requirements specified in the standard .
