Common material grades of blanking die steel

Recent research has revealed a close relationship between failure mechanisms and the properties of tool and die steels. Therefore, when selecting a suitable steel type (especially cold work tool and die steel), its failure mechanism should be fully considered.


Austenitic stainless steel


The most common problems in austenitic stainless steel blanking are adhesive wear, chipping and die sticking. Initially, the material to be processed is soft and therefore easily adheres to the mold surface; as it is work-hardened during the forming process, high stress is generated, which may cause defects and cracks. Production batch size, plate and sheet thickness are also important factors in selecting tool and die steel. These problems can be improved by selecting mold materials that resist adhesive wear and chipping.


Powder steel (such as PMX4, PMX5, PMX8 and PMX50 are particularly suitable for molds with long life requirements. DYX11S, DYCM8S, DYCM7 and UINPM are more suitable for short to medium life molds).


Advanced high-strength steel (AHSS)


The hardness and tensile strength of advanced high-strength steel plates require that mold materials must be resistant to wear and chipping and cracking. These are particularly important for ultra-high strength steels and martensitic stainless steels. Therefore, mold materials should have multiple properties.
