Introduction of NM 500 steel plates
NM 500 steel plates are abrasion-resistant steel plates with a hardness of 500 HBW. The strength of the NM500 steel plate is higher than that of ordinary low alloy steel plate, and the wear-resistant performance has been improved by 2-3 times. Excellent wear resistance significantly extends the service life of the steel plate.
Key characteristics of NM500 steel plates
High wear resistance: The particles of carbides in the NM500 steel plate are small and evenly distributed, so the wear resistance is higher.
High-temperature oxidation resistance: Under the condition of low sulfur content, the steel plate has good corrosion, and the corrosion resistance is significantly improved with the increase of the ambient temperature.
Excellent tempering stability: After tempering treatment, the NM500 steel plate has high strength, high hardness, good shaping ability, and is not easy to crack.

NM 500 steel VS Hardox 500 steel
The main differences between the two steel plates will be introduced from five aspects: chemical composition, wear resistance, application, cost, and processing.
1. Chemical composition
From the chemical composition point of view, the chromium content of the Hardox500 steel plate is up to 2.2%, and the chromium content of the NM500 steel plate is 0.7%-1%. The Cr content of Hardox500 steel plate is relatively high, which helps to form a denser oxide film and increase wear resistance and corrosion resistance.
2. Wear-resistance
NM500 steel plates provide wear resistance mainly in mechanical equipment. However, the Hardox500 steel plate can provide higher wear resistance due to its advanced production standards and technology. In comparison, under extreme wear conditions, Hardox500 steel is superior to NM500 steel.
3. Applications
NM500 steel: excavator buckets, truck beds, crushers, chutes, etc.
Hardox500 steel: dump truck bodies, conveyor systems, mining equipment, etc.
From aspects of uses, Hardox500 steel plate is more suitable for extremely harsh wear-resistant working environment such as mining, underground, coal mining, and other industries.
4. Cost
The cost is the most important thing that clients concerned. Hardox 500 steel plate is a world-renowned steel plate with excellent wear-resistance. Thus, the NM500 steel plate is cheaper than the Hardox 500 steel plate.
5. Processing
Hardox steel plates often require more advanced technology and hardware facilities for processing such as cutting, drilling, bending, welding, etc. This increases the difficulty and cost of processing. For example, because the Hardox500 steel plate has a relatively low carbon equivalent, it has better resistance to hydrogen-induced cracking than the NM500 steel plate. The Hardox500 steel requires tighter control of the preheating temperature when welding.
