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)

Applications

Ideal for mining equipment, excavator buckets, truck bodies, crushers, loaders, and construction machinery — wherever high wear resistance and impact strength are required simultaneously.

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
