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.

Key Features
High Wear Resistance: Outstanding performance under sliding, impact, and abrasive conditions.
High Strength: Supports heavy-duty applications and high loads.
Good Toughness: Maintains impact resistance even in low-temperature environments.
Weldable & Machinable: Suitable for various structural components and field installation.
Uniform Hardness: Ensures consistent wear resistance throughout the plate thickness.
NM500 steel plate application:
1. NM500 wear-resistant steel plate can be used in the production of 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.

2. 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.

What is the difference between Hardox 500 and NM500?
NM500 exhibits a hardness that typically fluctuates between 470-540 HBW, slightly edging out Hardox 500, which generally hovers around 470-530 HBW. This hardness is a key indicator of their prowess in withstanding the effects of abrasive wear and impact.
Do I need preheating before welding NM500 steel?
Preheating is recommended depending on:
Plate thickness
Ambient temperature
Welding method
Typically, preheating between 100–150°C helps reduce the risk of cracking.
What cutting methods are suitable for NM500 steel?
NM500 steel sheet can be cut using:
Plasma cutting
Laser cutting
Oxy-fuel cutting
Correct cutting parameters help maintain edge quality and performance.
Can NM500 steel be bent or formed?
Yes. NM500 steel can be bent with proper equipment. A larger bending radius is required compared to structural steel due to its high hardness.
What thickness range is available for NM500 steel sheets?
GNEE Steel typically supplies NM500 steel sheets in thicknesses from 6 mm to 80 mm, depending on production capability and customer requirements.
