Introduction of Wear Resistant Steel
The Lianyuan steel high-toughness crack-resistant wear-resistant steel NM400Tuf-NM500Tuf is the latest upgrade in the series of traditional wear-resistant steels. While maintaining the same level of strength and hardness as comparable products, it significantly improves impact toughness, effectively inhibiting steel plate cracking and crack propagation. It currently offers the best strength-toughness balance among engineering machinery wear-resistant steels in the domestic market. The NM450Tuf product achieves impact performance of over 100J at -20°C, which is approximately 60%-80% higher than traditional wear-resistant steels and four times the requirement of the national standard.
