Q460NH steel for railway rolling stock, AR400 wear-resistant plate is a special structural steel plate with high wear resistance, and is an important high-tech wear-resistant steel material. After quenching or quenching and tempering heat treatment, AR400 wear-resistant plate has a dense martensite or martensite-bainite microstructure. The thickness of AR400 wear-resistant plate can reach 100mm. The AR400 wear-resistant plate is widely used in loading machinery, construction machinery, agricultural machinery, mining machinery, metallurgy, electric power and other fields.

EN10083-3 42CrMo4 steel plate delivery status: Heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment delivery status should be specified in the contract. EN10083-3 42CrMo4 steel plate equivalent materials: JIS SCM440, AISI 4140, GB 42CrMo, Q460NH steel for railway rolling stock etc. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness.

Ultrasonic flaw detection emits ultrasonic waves to the Q460NH steel for railway rolling stock steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the Q460NH steel for railway rolling stock steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
