APPLICATION
8407 steel has a wide range of applications in the field of die-casting molds, especially suitable for die-casting molding of non-ferrous metals such as aluminum, magnesium, and zinc. 8407 steel has excellent high-temperature strength and thermal fatigue resistance, and can withstand the harsh working conditions of repeated impact and rapid cooling of molten metal.
8407 steel has become a commonly used material in plastic mold manufacturing due to its excellent polishing performance and corrosion resistance. It can achieve mirror level surface treatment, meet the appearance requirements of high-end plastic products, and resist the corrosion effect of plastic melt, extending the service life of molds. 8407 steel is particularly suitable for injection molding of precision electronic components and automotive parts.
8407 steel is also widely used in the field of hot work molds such as hot forging dies and extrusion dies. The balanced combination of wear resistance and toughness enables 8407 steel to withstand severe friction and impact loads during metal forming processes, playing a key role in component production in industries such as automotive and aerospace.
8407 STEEL CHARACTERISTICS
8407 steel, as a high-quality hot work die steel, exhibits comprehensive characteristics. This type of steel has excellent performance in high temperature strength, wear resistance, and thermal fatigue resistance, making 8407 steel an important choice material in the field of mold manufacturing.
8407 steel has excellent hardenability and can achieve uniform hardness distribution after appropriate heat treatment. This characteristic ensures stable performance of the mold from the surface to the core, making it particularly suitable for the manufacturing and use of large molds.
8407 steel can maintain high strength and hardness even in working environments above 600 ℃, and its ability to resist high-temperature softening makes it particularly suitable for high-temperature forming processes such as die-casting.
After overheating treatment, 8407 steel forms a dense hardened layer on the surface of the material, which can effectively resist wear caused by metal flow and significantly extend the service life of the mold under harsh working conditions.
The thermal fatigue resistance of 8407 steel makes it excellent in environments with drastic temperature changes. The special microstructure of 8407 steel can effectively suppress the generation and propagation of hot cracks, ensuring the stability of the mold during repeated heating and cooling processes.
8407 steel has good toughness reserves while maintaining high hardness. The balanced mechanical properties of 8407 steel enable it to withstand impact loads during the forming process, avoiding brittle fracture of the mold.
8407 steel can form a protective oxide layer after appropriate treatment. This characteristic makes it perform well in plastic mold applications and can resist the erosion of corrosive plastic melts.
