Innovative Metallurgical Engineering for Superior Tooling and Dies

Sun Steel Treating’s Ionitriding® is the solution for advanced metal stamping operations as well as precision tool and die makers. Our trademarked ion nitriding / plasma nitriding process provides tooling and die equipment with:

  • Higher fatigue strength.
  • Improved resistance to wear and corrosion.
  • Extended service life for automotive tooling.
  • Less maintenance requirements.

Ion Nitriding for Hot Formed and Forged Tooling

Hot formed and forged tools and dies typically require specialized maintenance and costly repairs. That equates to a downtime in manufacturing and reduced productivity. Sun Steel’s innovative plasma nitriding process gives metal stamping shops a low-temperature, environmentally friendly thermal treatment solution. Our trademarked Ionitriding® process yields extremely durable, wear-resistant cases for virtually any forged tool and die equipment.
