P20
The P20 Steel is a type of mold welding consumable, and the earliest is P20, followed byP20H and P20Ni. The P20 Steel is applicable to the production of molds for plastic materials,as well as those for diecasting low melting point metals. This steel material features greatmachinability, as well as mirror polishing properties.
718
The 718 Mold Steel, known as 3Cr2NiMo in China, is an enhanced steel on the basis of P20(3Cr2Mo). The quality of the steel material has been so greatly improved that it is able tocompensate for the weaknesses of the P20 Mold Steel, and at the same time meet therequirements that are beyond P20. Among today's mold steel materials in China, there is alsoP20+Ni, in addition to the above-mentioned Chinese standard steel grades.
