What Is Wear Resistant Steel Plate？
Product Definition：
Wear resistant steel plate is a high-strength specialty steel plate designed for applications involving severe abrasion, impact, and wear. Through optimized alloy composition and quenching + tempering heat treatment (also known as quenching and tempering), the steel achieves high hardness (typically 360–550+ HBW) while maintaining good toughness and weldability--2. The “NM” designation stands for “Nai Mo”, the Chinese pinyin for wear resistance, with the number indicating the nominal Brinell hardness value-2-7.
Key Characteristics：
| Feature | Description |
|---|---|
| High Hardness | 360–550+ HBW (Brinell hardness) – provides excellent resistance to abrasive wear |
| High Strength | Yield strength from 840 MPa to 1300+ MPa, tensile strength up to 1600+ MPa-2-1 |
| Good Toughness | Optimized alloy design maintains impact resistance even at high hardness levels |
| Excellent Weldability | Suitable for welding using standard procedures (preheating may be required for thicker plates) |
| Good Formability | Can be cut, bent, and fabricated into various shapes |
| Cost-Effective | 3–5x longer service life than ordinary carbon steel – reduces downtime and maintenance costs |
| 100% Recyclable | Environmentally friendly with no loss of properties |
