Site laboratory testing strands mechanical properties of Inquiry

Site laboratories test in raw material properties, often due to testing equipment and site relatively simple, Some of the mechanical properties of quantitative indicators is difficult to control, quality control is weakness in the testing, Based on the mechanical properties of steel strand test laboratory at the site of the actual application, analyze and explore non-strand extension ratio, the most vigorously total elongation parameters such as test methods and procedures and principles, Testing technology for general reference.
