Minkor is a corrosion-resistant tool steel that offers ease of machining and reliable processes. It allows for nearly one-third faster deep cooling boreholes and complex milling work.

When working with corrosive plastics, selecting a resistant mold steel is crucial for the mold's lifespan.

Properties, Technical Data, and Processing
  • Fully hardened to 280-325 HBW
  • Good weldability (preheat to 100°C)
  • Corrosion-resistant (comparable to 1.2085/1.2316)
  • Dimensionally stable
  • Significantly tougher than others (Impact toughness ISO V-notch: MINKOR: 10-12 Joule; 1.2085/1.2316: 4-6 Joule)
  • Excellent drillability, even in cooling boreholes
