GB/T 5028-2025 "Metal materials, thin plates and thin strips Determination of tensile strain hardening index (n value) " specifies the measurement method of tensile strain hardening index (n value) of metal thin plates and thin strips. The standard specifies the test principle, sample preparation, instrument requirements, test procedures and result calculation. It is suitable for evaluating the hardening characteristics of materials during tensile deformation, and provides a unified technical basis for the molding process design, quality control and performance research of metal thin plates and strips.
