Detailed Product Description: | Due to the high demand for mold surface quality and distortion, high-pressure gas quenching vacuum mold heat treatment has almost become an irreplaceable technology. Currently in the south and east coast, slightly scale private heat treatment processing enterprises have at least one 0.4MPa (most have six) high pressure gas quenching vacuum heating furnace. In the cutting tool industry, widely used in CNC and machining centers, strong demand tools with high quality and long life, while the city's environmental protection also proposed more stringent requirements for heat treatment of imported RD25, high-pressure gas quenching vacuum heating has also become high-speed steel cutting tools Hardening of an alternative salt bath heat treatment process first. FDAC mold steel with a rapid tooling, excellent high temperature strength and wear resistance, hardness at the factory has reached HRC40-44, so no heat can be used directly in production, can greatly reduce the processing time to die. But overall, the current Zhongshan mold steel market still lags behind the needs of mold industrial development. According mold experts, a considerable part of the requirements of high mold steel need to go through the vacuum refining and remelting to ensure high purity steel, high density, higher anisotropy, of which more than general quality mold steel, high-quality less RD25 tungsten steel mold steel, and die steel by remelting share is small. Zhongshan die steel market is about 80 percent black round bar RD25, at present, alloy tool steel output in China has been in the world, of which about 100,000 tons alloy tool steel. Eutectoid steel and forgings for eutectoid steel, or tools, dies, ball bearing steel rod pearlite RD25, the ball carbide, refine the organization, eliminate stress, reduce hardness, improved ductility, toughness. Heated to 20-30 degrees Celsius above Ac1 annealing, Ac1 20-30 degrees Celsius above the ball. Heating holding time and fully annealed same. When cooled to 20-30 degrees Celsius per hour speed of the ball is cooled to a temperature, the ball after cooling to 450-500 degrees Celsius oven baked. With various domestic operating costs increased year by year, the steel infrastructure ideas also tend to go out, Southeast Asia, such as Indonesia, Myanmar, Vietnam is becoming a popular investment treasure. Indonesia, which is due to make policies to attract a large number of domestic manufacturers to invest settled, but factors such as political instability in Indonesia this year, firmly implement the ban on mining, investors wait and see situation in subsequent indecisive, the actual start start building or less.
