Areas of use

• Metal forming dies up to 500°C
• Molds and transport elements for plastics
• Die-casting tools

Material groups

• Tool steels
• Powder metallurgy materials
• Special materials

The advantages

• The supporting effect of the nitrided layer reduces the “eggshell effect” and reduces wear on the functional layer
• Significant increase in the service life of tools and machines
• Avoids abrasive and adhesive wear
• Improves demolding characteristics
• Very good coating adhesion
