Microstructures And Wear Resistance Behaviors Of Nm400 Steel Hardened

Microstructures and Wear Resistance Behaviors of Nm400 Steel Hardened

NM400 wear-resistant plate is a kind of high-strength, high-toughness, wear-resistant steel plate, which is often used in mining, steel, cement and other fields. Under normal circumstances, the hardness of NM400 wear-resistant plate after annealing is about 250-300HBW. Moreover, after annealing, the internal stress of the NM400 wear-resistant plate will be released, and there will be a certain plasticity and toughness improvement, so as to play a better supporting role for some projects and applications.
