Nm500 Wear-Resistant Steel Plate
NM500 wear-resistant steel plates have a long service life, reducing equipment downtime for maintenance and lowering maintenance costs by 40-60%; they are also lighter than castings with equivalent protective performance, reducing equipment energy consumption by 10-15%. Leading China supplier control the source, providing complete quality traceability and supporting third-party testing to avoid substandard products.
The carbon content of NM500 wear-resistant steel plates is controlled between 0.28-0.32%, ensuring both hardness and avoiding brittleness, allowing them to withstand strong impact loads without easily cracking. The chemical composition table for NM500 wear-resistant steel plates is available; custom alloy ratios can be made for special applications: high-temperature resistant types increase tungsten (W) content (0.15-0.25%), while corrosion-resistant types increase chromium and nickel content (3.0-3.5% Cr, 1.0-1.5% Ni).

Wear Resistance
Wear resistance is 3-5 times that of ordinary Q235 steel plate, 30-50% higher than NM400, and 50-80% higher than NM360.
Utilizing a quenching and tempering heat treatment process, a uniform martensitic structure is formed, and the dispersed carbide reinforcing phase provides long-lasting wear resistance.
Wet sand abrasion test (ASTM G105 standard) shows a wear rate of only 0.08 g/cm², far lower than ordinary wear-resistant steel.
