NM500 Steel: An Abrasion Resistant Steel with 500HB

1. What is NM500 Steel?

NM500 Steel is one steel grade in GB standard GB 24186. 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. 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. The strength of NM500 wear-resistant steel is more than 3 times that of ordinary low-alloy steel plates, and the wear-resistant performance can be increased by 2-3 times, significantly extending the service life of the steel plates.

7. Application of NM500

NM500 steel is widely used in industries that require high wear resistance. Some of its primary applications include:

Mining equipment
Construction machinery
Heavy-duty trucks
Industrial machinery
Wear plates and liners

NM500 wear-resistant steel plate can be used to produce various mechanical components such as: bearing races, crankshaft sleeves, piston rods, oil pump rotor bodies, cam pin linings; engine connecting rod bolts, nuts, washers and set screws; hydraulics Cylinder plunger ring, valve core seal; diesel engine cylinder head cover, valve lifter; tractor blade edge, chain rail joint lock block, mud scraper baffle, etc.

NM500 plates can also be used in the field of engineering and construction, and can be used in welding seam surfacing layers of bridge support beam welded components, extended anchor sections of railway track sleepers, drilled concrete prefabricated pile heads into retaining pipes, highway pavement base paving materials and various metals Anti-corrosion protective coatings for structures, etc.

NM500 steel stands out as a top choice for applications requiring superior wear resistance. Its unique combination of hardness, strength, and durability ensures extended service life in the most challenging environments. Whether you’re in mining, construction, or any industry in between, NM500 steel promises to deliver unmatched performance.
