Giga Steel(1.5GPa) Knives specifically for ultra-high tensile steel (DY-7)

  • heat treatment hardness HRC 62~64 avatar: 1.5GPa High-alloy tool steel optimized for slitting Giga Steel and high-strength steel plates.
  • fine chipping(Micro-Chipping) complete control: Maximizes toughness and wear resistance with fine and uniform carbide structure.

Steel Industry Expected effects when applying the line

  • Maximize facility productivity: Line stoppage due to extended knife replacement cycle(Downtime) minimize
  • Reduce maintenance costs: Improved durability compared to our existing knives
  • Secure ultra-precise quality: Burrs generated during slitting of Giga Steel(Burr)Ensures perfect cutting surface quality by minimizing
