ActiveSheet metal formability and test methods - Part 4: Method of hole expanding test
金属薄板成形性能与试验方法 第4部分：扩孔试验
Application Summary AI generated
This standard specifies the hole expanding test method for evaluating the formability of sheet metal. It is applied in the automotive, aerospace, and appliance industries to assess a material's resistance to edge cracking and its ability to stretch around a hole during stamping or forming processes. The test is used for quality control and material selection in manufacturing environments where sheet metal undergoes severe deformation.
