Product Introduction

The anti-corrosion nm400 wear-resistant steel plate is treated with anti-corrosion technology, which can effectively prevent or slow down the corrosion of chemical or electrochemical reactions during transportation and use. Nm400 wear-resistant steel plate can effectively prevent or slow down corrosion, extend the service life of nm400 wear-resistant steel plate, and reduce the operating cost of NM400 wear-resistant steel plate.

NM400 wear-resistant steel plate is widely used in construction machinery, mining machinery, coal mine machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, shovel plate, side shovel plate, shovel knife. Crusher lining plate, blade.
