Weld-on Cutting

We supply NM400 material blades throughout the year. This is a highstrength, wear-resistant steel for construction machinery as specified by the Chinese national standard GB/T24186-2022. During manufacturing, the raw material undergoes heat treatment to achieve high hardness and wear resistance, significantly reducing delivery time. Compared to boron steels (27MnTiB, 30MnB), it offers superior Brinell hardness, yield strength, and tensile strength. Our steel plates also meet the impact

performance standards of boron steels (with impact energy greater than 40J at -20°C). Thanks to our nearly 20 years of collaboration with domestic steel mills, we are able to purchase NM400 steel plates in bulk and stock them for sale or cutting, ensuring maximum material utilization and offering you the best possible price.
