- Mar 29, 2018-

In China 718 is better than the P20 material, 718 and p20 are plastic mold steel, but 718 is p20 modified steel number, corresponding to the United States steel p20 + Ni. Although 718 uses the same as p20, 718 has better hardenability and superior performance. It can produce large-size, high-grade plastic mold forming parts. 300,000 molds are best secured with SKD61 heat treated material.
