NM500 wear-resistant steel plate
When to Choose NM400 vs. NM450 vs. NM500
Choose NM400 if:
The application involves moderate wear and abrasion.
Cost-effectiveness is a priority.
Choose NM450 if:
The application involves high wear and abrasion.
A balance between cost and performance is needed.
Choose NM500 if:
The application involves extreme wear and abrasion.
Maximum durability and wear resistance are required.
Application
Products Use:
Wear-resistant steel with high wear resistance and good impact performance, capable of cutting, bending, welding, etc., can be taken welding, plug welding, bolting and other ways to connect with other structures, with the province when in the course of the repair site , convenient, widely used in metallurgy, coal, cement, electricity, glass, mining, building materials, bricks and other industries, compared with other materials.
Wear resistant steel with 2 to 12mm in thickness are produced from processes of hot rolling, cutting into length and heat treating. The products are characterized with small thickness, good flatness, outstanding wear resistance, excellent toughness, good weldability, good machinablility, consistent property and quality. Wear resistant steels are developed for applications where high wear resistant performance is required, such as dumper, garbage vehicle, concrete mixer truck, industrial air fan, hopper, crusher, machinery for coal, grain, cement, grab bucket, etc

FAQ:
1.What is NM400 steel?
NM400: A Chinese-standard wear-resistant steel (NM stands for "Nai Mo," meaning wear-resistant in Chinese), NM400 typically has a Brinell hardness (HBW) of 360–440. It's known for its balance of hardness, toughness, and cost-effectiveness, making it popular in Asia and beyond.
2.What is NM500 steel?
NM 500 steel is a high-strength, wear-resistant / abrasion resistant steel known for its superior hardness and durability. This steel is specifically designed to withstand high wear conditions and provide extended service life in challenging environments.
3.What is the difference between Hardox 500 and NM500?
Hardness: NM500 typically has a hardness range of around 470-540 HBW (Brinell hardness), while Hardox 500 typically falls within the range of 470-530 HBW. The hardness level indicates their ability to withstand abrasive wear and impact.
4.What is the hardness of NM500?
With a hardness range of 470-540 HBW, NM500 is widely used in applications where resistance to abrasion is a primary concern, such as in mining equipment, construction machinery, and other heavy-duty applications.
5.What is the difference between AR500 and NM500 steel?
Key implication: AR500 is preferred in North America for compliance with ASTM certifications, while NM500 dominates Asian markets . Both steels exceed 500 HBW surface hardness, but AR500 shows marginally higher tensile/yield strength and better low-temperature toughness.
