Welding Hardox steel requires care, especially for higher hardness grades. Key guidelines include:

  • Preheating: Required for grades 500 and above to reduce the risk of cracking.
  • Controlled Cooling: Avoid rapid cooling after welding to maintain structural integrity.
  • Matching Electrodes: Use electrodes or filler materials designed for AR steels.
  • Avoid Overheating: Excessive heat can reduce hardness in the heat-affected zone (HAZ).
