NM500 High Strength Wear Resistant Steel Plate with 3/16 Thickness and 70,000 - 100,000 Psi Tensile Strength
NM500 Steel is a high-strength wear-resistant steel within GB standard GB 24186, known for exceptional hardness, durability, and abrasion resistance. Its excellent toughness makes it ideal for demanding industrial applications requiring superior wear resistance.
- High Wear Resistance: Exceeds ordinary steel by 15-20 times, low-alloy steel by 5-10 times, and high-chromium cast iron by 2-5 times.
- Superior Impact Performance: Wear-resistant layer withstands medium impact while substrate carries load.
- Excellent Heat Resistance: Recommended for ≤600°C use, with alloy additions extending to ≤800°C.
- Corrosion Resistance: High chromium content provides significant rust protection.
- Workability: Easily cut, bent, welded, punched, and formed into various components.
