10mm 20mm NM500 High Strength Wear Resistant Steel Plate

NM500 is a high-strength wear-resistant steel plate‌, characterized by a Brinell hardness of approximately ‌500 HBW‌. It is engineered for severe wear conditions, offering extended service life and reduced maintenance needs.

Through ‌quenching and tempering treatment‌, NM500 develops a hard martensitic microstructure, making it ideal for ‌excavator buckets, crusher liners, dump truck beds, and conveyor chutes‌-components exposed to constant impact and abrasion.

Its superior wear resistance helps ‌extend maintenance intervals and reduce unplanned downtime‌, thereby lowering operational expenses and capital investment.

NM500 Wear Resistant Steel Plate

N is the first pinyin letter of "Nai" in "Wear".

M is the first pinyin letter of "mill" in "wear-resistant".

500 is the Brinell hardness value HB value. (500 hardness value is broad, domestic NM500 hardness value is about 500.)

Grade classification: NM500A NM500B

Heat treatment: quenching and tempering (quenching + tempering).

Application: NM500 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts. 

Suitable for manufacturers of construction machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, etc. Can be used on excavator, loader, bulldozer bucket blades, blade plates, side blades, blades, crusher liners, etc.

 Mining machinery: Liners, blades, conveyor liners, and baffles for mineral processing and crushing machines. These components require extremely high wear resistance, and the available materials are NM450/500 and HARDOX450/500 wear-resistant steel plates with a thickness of 10-30mm.

 Loading machinery: unloader chain plates, hopper liners, grab bucket plates, automatic tipper truck unloading plates, tipper truck bodies. This requires wear-resistant steel plates with extremely high wear resistance and hardness. It is recommended to use NM500 HARDOX450/500 wear-resistant steel plates with a thickness of 25-45 mm.

 Construction machinery: Loaders, bulldozers, excavator bucket plates, side blades, bucket bottom plates, blades, and rotary drilling rig drill rods. These machines require steel plates with extremely high strength and excellent wear resistance. Optional materials include 20-60mm thick NM500 and HARDOX500/550/600 high-strength wear-resistant steel plates.

FAQ：

1.What is NM500 steel?

NM500 steel is a high-strength wear-resistant structural steel‌, designed for severe wear conditions. It undergoes quenching and tempering to form martensite or bainite microstructures, delivering excellent resistance to impact and abrasion.
Common applications include ‌excavator buckets, crusher liners, dump truck beds, and conveyor chutes‌, especially in mining, construction, and heavy machinery industries.

2.What is the difference between Hardox 500 and NM500?

Hardox 500 is an imported premium wear plate from SSAB (Sweden)‌, known for superior toughness, consistent quality, and excellent performance in extreme conditions.
‌NM500 is a Chinese equivalent‌, meeting national standards with competitive performance and cost-effectiveness. While similar in hardness, Hardox 500 generally offers better low-temperature toughness and material uniformity.

3.What is the difference between AR500 and NM500?

AR500 is an American abrasion-resistant steel‌ commonly used in North America, particularly in mining trucks and ballistic protection.
‌NM500 is its Chinese counterpart‌, engineered with a balanced alloy design to improve weldability and toughness under domestic manufacturing conditions.

4.Is AR500 the same as Hardox 500?

While both AR500 and Hardox 500 have a hardness of ~500 HB‌, ‌Hardox 500 outperforms AR500 in toughness, tensile strength, and cold-weather performance‌. It is often considered a premium upgrade for users seeking longer service life and higher safety margins.

5.What is the hardness of NM500?

‌The Brinell hardness of NM500 ranges from 470 to 540 HBW‌, making it highly resistant to abrasion. This level of hardness significantly extends equipment life in demanding applications such as ‌mining, construction, and material handling‌.
