[0002] The quality inspection of steel bars mainly includes three parts: mechanical properties, process properties, and mechanical properties. The mechanical properties of steel bars refer to the laws of reactions and changes when steel bars are subjected to forces, including the yield strength, tensile strength, and elongation of steel bars. The inspection of the mechanical properties of steel bars mainly adopts non-destructive inspection methods: randomly select samples, cut samples at both ends of the samples, and then place them on a marking machine for chiseling and marking in situ (the marking machine is also called a continuous marking machine or a distance gauge. It is used to mark round steel, flat steel, steel pipes, steel sections, and other non-ferrous metal materials for tensile testing).
