With the help of two different methods, the yield strength, tensile strength, elongation after fracture, tensile strain hardening exponent (n) value and plastic strain ratio (r) value of cold-rolled sheet produced by Baotou Steel were determined. The experimental data obtained from the two different methods had been compared. The results showed that the method of automatic measurement with an optical non-contact extensometer was with better reliability and reproducibility.
