Life of 718H melamine tableware Compress mold
718h mold steel has the same use as P20 mold steel, but because of better hardenability and superior performance, it can produce large-scale, high-grade plastic mold forming parts, which is an advanced plastic mold steel. 718h mold steel hardness can be understood from two aspects.
① Hardening treatment In order to improve the life of the mold to more than 800,000 mold times, it can pre-harden the mold steel. Hardening and low temperature tempering are used to achieve this. During quenching, it is preheated at 500-600 ℃ for 2-4 hours, and then kept at 850-880 ℃ for a certain period of time (at least 2 hours). It is cooled in oil to 50-100 ℃ and air-cooled. The hardness after quenching can reach 50 -52HRC, in order to prevent cracking, a low-temperature tempering treatment at 200 ° C should be immediately performed. After tempering, the hardness can be maintained above 48HRC.
② Nitriding. Nitriding treatment can obtain a high hardness surface layer structure. The hardness of the surface layer after nitriding can reach 650-700HV (57-60HRC). The mold life can reach more than one million times. The nitrided layer has the characteristics of dense structure and smoothness. Improved anti-corrosive performance against humid air and lye.
