Treatment process: tungsten-cobalt solution infiltration method
Theoretical weight table (unit: kg/m, mm): 14.5
YG8 is a tungsten-cobalt-based material. Good abrasion resistance, use strength and impact toughness are better than YG6. Drawing dies under high stress conditions, suitable for drawing steel with a diameter of <50mm, non-ferrous metal wires and their alloy wires or bars, and also used for small size stamping dies and rivet top forging dies with low working load . YG8 molding material. Without heat treatment, the inner and outer hardness is uniform.
