AbolishedMetallic materials - Sheet and strip - Hole expanding test
金属材料 薄板和薄带 扩孔试验方法
Application Summary AI generated
This standard specifies a test method for evaluating the stretch-flangeability of metallic sheet and strip materials by measuring the hole expansion ratio. It is applied in the automotive, aerospace, and appliance industries to assess the edge cracking resistance of advanced high-strength steels and aluminum alloys during forming processes. The test is critical for quality control and material selection in stamping and deep drawing operations.
