    Cold Forging Quality Steels

    Material quality requirements for cold heading steels

    • Excellent surface quality ensuring zero-defect situation so that forged components have no defects
    • Good control over ovality to ensure smooth forging process.
    • Good control over mechanical properties such as tensile strength and reduction is to ensure proper cold forgeability and productivity
    • Completely descaled surface to avoid forging defects such as scale pits and resultant surface roughness.
    • Suitable metallurgical structure to ensure proper machinability level.
    • Good and uniform response to heat treatment since the components are always treated in bulk.
