NM400 abrasion resistant steel plates for construction machine

NM400 abrasion resistant steel plates for construction machine

Pageviews:

NM400 abrasion resistant steel plates are weldable steel for high-strength structure, and the excetive technical standard is GB/T 24186. The equipment manufactured with NM400 abrasion resistant steel plates is suitable for high wear and high impact occasions. Under the premise of not losing strength, NM400 abrasion resistant steel plates have good impact toughness and welding performance.
