1. Material Characteristics

Angle steel high-speed steel rolls are made from high-speed steel containing high-alloy elements such as tungsten (W), molybdenum (Mo), vanadium (V), and chromium (Cr). Their characteristics include:
    •    High Hardness: Surface hardness can reach HSD82-89 or higher after specialized heat treatment, meeting the demands of high-strength rolling.
    •    Excellent Wear Resistance: Significantly extends roll service life and reduces replacement frequency.
    •    High Red Hardness: Maintains stable performance even under high-temperature conditions.
    •    Thermal Fatigue Resistance: Withstands thermal cycling, preventing thermal cracks and surface spalling.

2. Performance Features

    •    Wear Resistance: Suitable for continuous production under high-load conditions, extending roll lifespan.
    •    Thermal Stability: Maintains dimensional accuracy and shape stability in the high-temperature environment of                angle steel rolling.
    •    Impact Resistance: Handles the alternating loads and impacts during angle steel rolling.
    •    High Precision Rolling: Ensures dimensional consistency and accurate cross-sectional shapes of angle steel.

3. Applications

piercing mills, reducing mills, and sizing mills, ensuring extended roll life and excellent surface quality of the final pipe products


4. Technical Advantages

    •    Increased Production Efficiency: High wear resistance and hardness reduce downtime, enhancing continuous production efficiency.
    •    Lower Production Costs: Longer service life reduces roll replacement frequency and maintenance costs.
    •    Improved Product Quality: Ensures smooth surface finish, precise dimensions, and complete cross-sectional shapes of angle steel products.
