Grade: YL80 Density :13.75-14.05 bending strength: ≥ 3200 Hardness: ≥ 89.5 Usage: has a high hardness and toughness, the electronics industry and for the production of sheet metal stamping dies. Also be used for cold heading industry strong beam molds. Carbide Features: 1, die life extension (fatigue strength is high, not prone to stress concentration) 2, long life and good stability (the occurrence of cracks and expansion time delay) 3, adhesion, bite wounds significantly reduced (lubricant corrosion resulting extremely slight) 4, wire EDM process greatly improved the corrosion resistance (anti-corrosion ability EDM)
