In addition to strength and stiffness, stamping materials must meet the requirements of stamping process.

The quality of materials directly affects the design of stamping process, the design of die, the service life of die, the quality and service life of stamping products, as well as the cost of stamping parts. Therefore, on the one hand, it is necessary to improve the structural workability of stamping parts through product design to send the deformation conditions of materials in stamping process so as to reduce the quality of materials. On the one hand, materials with suitable stamping properties should be selected to meet the deformation requirements of stamping process. Therefore, when choosing stamping materials, it is necessary to scientifically and reasonably evaluate the stamping properties of materials, and correctly grasp the relationship between stamping properties and stamping formability, so as to give full play to the plastic deformation ability of materials and reduce the composition of materials.
