    High toughness crack-resistant and wear-resistant steel NM400Tuf-NM500Tuf, the latest upgrade of traditional wear-resistant steel, is the best strength and toughness matching wear-resistant steel for construction machinery in the domestic market, of which the cracking and crack propagation can be effectively inhibited by greatly improving impact toughness under the premise of ensuring the same level of product strength and hardness unchanged. The impact property of NM450Tuf at -20℃ can reach more than 100J, which is about 60%-80% higher than the traditional wear-resistant steel, up to 4 times of national standard.
