When choosing between Hardox grades, consider these factors:

  1. Wear Resistance: Higher grades like Hardox 500/600 offer superior resistance to abrasive wear.
  2. Toughness: Grades like Hardox 400 or HiTuf have better toughness, making them suitable for impact-heavy environments.
  3. Weldability and Machinability: Lower grades (e.g., Hardox 400) are easier to work with, while higher grades may require specialized techniques.
  4. Thickness: Thickness influences the balance of toughness and hardness. Thicker plates may demand lower hardness to maintain structural integrity.
  5. Cost: Higher hardness grades generally cost more due to their advanced processing.
  6. Application: Match the grade to your specific application—e.g., mining buckets require high abrasion resistance (Hardox 500), while truck bodies may use Hardox 400 or 450.
