304 stainless steel occupies an important position in the manufacture of hardware stamping parts with its excellent corrosion resistance and high strength. However, the hardness and toughness of this material also put forward special requirements for mold design and material selection.
In terms of mold design, due to the high hardness of 304 stainless steel, the mold must have sufficient strength and wear resistance. Therefore, the design of the mold needs to fully consider the mechanical properties of the material and the requirements of the stamping process. The mold structure should be reasonable, and the design of the stress-bearing parts needs to be accurately calculated to ensure that the mold can withstand huge pressure during the stamping process without deformation or damage.
In terms of material selection, the mold material must have high hardness, high wear resistance and good toughness. Commonly used mold materials include high-speed steels such as H13, SKD11 and SKH-9, as well as cemented carbide. H13 steel is suitable for stamping dies for large and thick plate parts, and has heat resistance, wear resistance and good toughness. SKD11 steel has a high hardness and is suitable for the manufacture of precision stamping dies, and the mold life is long. SKH-9 high-speed steel has good hardness and toughness, and is suitable for the manufacture of small and medium-sized molds. It has good processing performance and wear resistance, and its cost is relatively low. Cemented carbide is suitable for large-scale, high-strength stamping processing, but its cost is relatively high.
In addition, the surface treatment of the mold is also very important. By polishing and hardening the mold surface, the wear resistance and corrosion resistance of the mold can be further improved, and the service life of the mold can be extended.
In summary, the mold design and material selection of 304 stainless steel stamping parts need to fully consider the mechanical properties of the material and the requirements of the stamping process, select mold materials with high hardness, high wear resistance and good toughness, and carry out reasonable mold structure design and surface treatment to ensure that the mold can withstand huge pressure during the stamping process without deformation or damage, so as to produce high-quality 304 stainless steel stamping parts.
