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.
