4、 Report on yield strength testing machine for cold-rolled steel strip:

Cold rolled steel strip products need to undergo tensile testing to verify their strength limit, tensile strength, yield point elongation, total elongation at maximum force, and elongation at break. In addition, thin steel plates are usually tested to determine their tensile strain hardening index (n-1 value) and plastic strain ratio (n-1 value) in one or more regions of the tensile stress-strain curve.

Note: Steel strip production requires high experimental processing capabilities and very stable test results. The testing machine must have ease of use and high repeatability. The experimental control software not only needs to maintain precise control to obtain stable experimental speed, but also needs to adopt advanced algorithms to calculate the experimental results of various stress/strain curves.
