AbolishedMetallic materials - Sheet and strip - Determination of tensile strain hardening exponent
金属材料 薄板和薄带 拉伸应变硬化指数（n值）的测定
Application Summary AI generated
This standard specifies the test method for determining the tensile strain hardening exponent (n-value) of metallic sheet and strip materials. It is applied in the metallurgy and automotive industries to evaluate the formability and work-hardening behavior of thin metal sheets during stamping or deep drawing processes. The standard is used for quality control and material selection in manufacturing environments where consistent plastic deformation properties are critical.
