Product Details

NM400 Wear-Resistant Steel Helical Flight

Product Overview

The NM400 Wear-Resistant Steel Helical Flight is an ultra-durable conveying component specifically engineered for highly abrasive material handling applications. Manufactured by Jiahe Conveying Equipment Technology Co., Ltd, these flights utilize NM400 abrasion-resistant steel with a Brinell hardness of 370-430 HBW, delivering 3-5 times longer service life than standard carbon steel flights in extreme wear conditions.

Key Features

1. Exceptional Wear Resistance

  • NM400 steel construction (Brinell hardness 370-430 HBW)

  • Hardened surface treatment for maximum abrasion resistance

  • 5-8 times longer lifespan than standard carbon steel in abrasive applications

2. Heavy-Duty Structural Integrity

  • Thickness options: 8-30mm (standard), up to 50mm (custom)

  • Reinforced flight edges for impact resistance

  • High torsional strength for demanding material handling

3. Optimized for Harsh Environments

  • Suitable for materials with high SiO₂ content (sand, ores, slag)

  • Resistant to impact and gouging wear

  • Performs in temperatures from -40°C to +380°C

4. Custom Engineering Solutions

  • Variable pitch designs available

  • Hardfacing overlay options (up to HRC 60)

  • Special geometries for specific material flow requirements
