Japanese imports of tungsten carbide steel G5 G5 tungsten steel die steel is a specific category belong tungsten carbide, without heat treatment, inside and outside the uniform hardness. For volume production, with excellent strength and toughness, suitable for the production of drawn mold, wear-resistant parts and stamping parts and carbide automatic presses punch. Details :13.9-14.2 average density of particles: 1.6 Hardness: ≥ 87HRA bending strength (N/mm2): ≥ 2250 non-combined carbon: ≤ C02 phase: E00 porosity: ≤ A04, B04 chemical composition: wc: 85%, co: 15% Uses silicon steel sheet, cold rolled plate, suitable for the production of drawn mold, wear-resistant parts and stamping parts and carbide automatic presses punch such as the use and impact strength, good toughness, wear resistance than the alloy is low. Top load large forging dies, such as for screws. Rivet upsetting die. Also used for stamping die. Extrusion die. Die and so on.
