YG8 Mould Steel Bar
YG8 is tungsten-cobalt stamping die mould steel. With good abrasion resistance, 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 stamping dies and rivet top forging dies with small size and low working load . YG8 advanced molding material. Without heat treatment, the inner and outer hardness is uniform.
