718H mold steel, China's grade 3Cr2NiMo is an improved steel grade of P20 (3Cr2Mo), with significant improvements in quality, which makes it fill the shortage of P20 mold steel, to meet the occasion of P20 mold steel can not meet the requirements.

In addition to the above-mentioned Chinese standard steel grades, the steel grades currently appearing in China's mold steel market include P20 + Ni. Sweden's 718, 718H (ASSAB), PX5 \ PX4 (Datong Special Steel in Japan), GS-711, GS-738, GS-312, GS-318 (Thyssen, Germany), M238 ECOPLUS (Ballu) in Austria, CS718 (National Great Wall Special Steel), SWP20 (Shanghai No. 5 Steel Co., Ltd.) and so on, so in addition to not being used for plastic mold parts with corrosion resistance requirements, it is currently the most widely used general-purpose plastic mold steel typical steel grade.
