Wear-resistant steel sheet Nm500 with a thickness of 3-12MM has a hardness of HRC58-62. Its wear resistance is over 15-20 times that of ordinary steel plates, and over 5-10 times that of low-alloy steel plates, and over 2-5 times that of high-chromium cast iron. The Nm500 wear-resistant steel plate has a double-layer metal structure, with the wear-resistant layer and the base material being metallurgically bonded, resulting in high bonding strength. It can be applied in working conditions with strong vibration and impact. The wear-resistant steel plate sheet NM500 can be used at 500°C, and can be customized to meet requirements up to 1200°C. It not only ensures the toughness e plasticity of the wear-resistant steel plate but also provides strength to resist external forces. It can be used to manufacture buckets, loaders, dump trucks, crushers, powder separators, chutes, and various wear-resistant linings.

Why does NM500 have excellent wear resistance?
NM500 is designed with low-carbon alloy and various alloy elements are added. The quenching + tempering heat treatment process directly affects the final wear resistance of NM500. The uniform and fine tempered martensite structure makes the wear-resistant steel not only hard but also possess certain toughness.
How to store NM500 steel plates?
Store them in a dry and ventilated warehouse. Do not place the steel plates directly on the ground. Stack them by category. Apply anti-rust oil and package them with anti-rust paper. Be careful to prevent mechanical damage during handling. Keep away from acids, alkalis, and areas with long-term salt spray and standing water. Regularly check.
How long is the service life of NM500?
NM500 usually has a significantly longer service life than ordinary structural steel. The specific duration may vary depending on the working conditions.
What are the differences between NM500 and ordinary steel plates?
NM500 is specifically designed for high wear conditions, while ordinary steel plates are mainly used for general structural manufacturing.
What standards does NM500 comply with?
GB/T 24186
What are the advantages of NM500 over AR500?
The advantages of NM500 are more reflected in the supply chain, cost, processing support and delivery efficiency in the Chinese and Asian markets.
How to analyze the causes of cracks or abnormal wear?
The analysis should be conducted from aspects such as materials, processing, installation, working conditions and maintenance.
