NM450Tuf The Ultimate Solution for High-Toughness Steel Raw Material in Mining and Heavy Machinery
Product Overview:
The Tuf series wear-resistant steel (NM400Tuf, NM450Tuf, NM500Tuf) is an upgraded generation of high-toughness wear-resistant materials. Developed to combine superior strength, excellent impact toughness, and outstanding crack resistance, this steel ensures reliable performance in demanding applications such as mining, construction, heavy machinery, and material handling.
Key Mechanical Properties:
| Steel Grade | Tensile Strength (MPa) | Elongation After Fracture (%) | Hardness (HBW) | Impact Toughness AKV (J, -20°C) |
|---|---|---|---|---|
| NM400Tuf | ≥1200 | ≥10 | 420–480 | ≥48 |
| NM450Tuf | ≥1300 | ≥8 | 420–480 | ≥48 |
| NM500Tuf | ≥1500 | — | — | ≥36 |
Comparison Between NM450 and NM450Tuf:
| Property | NM450 | NM450Tuf |
|---|---|---|
| Tensile Strength (MPa) | 1420–1500 | 1420–1500 |
| Elongation (%) | 14–18 | 14–18 |
| Hardness (HBW) | 450 ± 15 | 450 ± 15 |
| Impact Energy KV₂ (J, -20°C) | 50–70 (typical 58) | 90–110 (typical 106) |
| Impact Energy KV₂ (J, -40°C) | 40–55 (typical 46) | 90–100 (typical 98) |
Performance Advantages:
Exceptional toughness: NM450Tuf achieves nearly double the impact energy of standard NM450, providing superior resistance to brittle fracture even under extremely low temperatures (-40°C).
Enhanced ductility and crack arrest ability: Ensures longer service life and safer operation in dynamic or high-stress environments.
Consistent hardness and wear resistance: Offers the same level of surface hardness as traditional NM steels while significantly improving toughness and reliability.
Why Choose the Tuf Series:
Improved safety and reliability under shock loads
Excellent low-temperature toughness and crack resistance
Long-lasting wear protection for extreme working conditions
