The diameter ratio (the ratio of fiber length to diameter, when the fiber section is non-circular, the diameter of equivalent section circle area) is 30-100. Bluing steel strip

Due to different preparation methods, the functions of steel fiber are very different, such as the tensile strength of cold drawn steel wire is 380-3000mpa, the tensile strength of cold rolled steel strip shear method is 600-900mpa, the tensile strength of ingot milling method is 700MPa; although the liquid steel condensation method is 380MPa, it is suitable for producing heat-resistant fiber.
