(6)Performance:
Air cooling and hardening type of hot-work die steel has excellent heat strength and hardness, high abrasive resistance and toughness and also pretty good property of resistance to cold and hot fatigue. |
(7) Applications:
For making forging dies of die forging hammer, hot extrusion dies, mandrels, die-casting molds of light metals like aluminum and zinc, tools used for hot upset forging structural steel and heat-resistant steel and dies used for high-energy-rate forging machine. |
