Impact Toughness Of An NM400 Wear-Resistant Steel
Impact Toughness of an NM400 Wear-Resistant Steel
The mechanical properties of NM400 wear-resistant steel plate are 3 to 5 times that of ordinary low-alloy steel plate; It can significantly improve the wear resistance of mechanical parts. Therefore, the service life of the machinery is improved and the production cost is reduced.
The standard wear-resistant steel plate is available in 1200 or 3800 by 12000 mm specifications, and can also be customized according to user requirements according to the drawing size. Wear-resistant steel plates are now divided into three types: ordinary, impact-resistant and high-temperature. The reasons for ordering high temperature wear and impact resistant composite steel plates should be stated. The thickness of the wear-resistant alloy layer is 3~20 mm. The small thickness of the composite steel plate is 6 mm, and the thickness is not limited.
