Scope

Scope: This standard specifies the terms and definitions, classification and marking, order content, dimensions and shapes, technical requirements, inspection methods, inspection rules, storage and transportation, packaging, marking, and quality certification documents for cold-drawn carbon steel wire used in industrial sieves. This standard applies to the manufacture of round cold-drawn carbon steel wire for industrial sieves. Main technical contents: 1. The material requirements are supplemented with "the quality of the wire rod shall comply with the requirements of GB/T 4357 standard", and the enterprise standard used by the factory when supplying the wire rod shall not be lower than this standard. The minimum carbon content is increased from 0.40% to 0.42%, corresponding to the lower limit of 45 steel. 2. The appearance and surface quality exclude "cracks, pits, and burrs", as such defects are prone to cause breakage during the wave pressing of the steel wire. 3. The mechanical properties stipulate a wide range of tensile strength, so it is added that "the buyer may specify a narrower tensile strength range, and the strength range is recommended to be not less than 200MPa." Special requirements shall be negotiated separately. The cross-sectional shrinkage rate is required because low-plasticity materials are not suitable for the wave pressing processing of sieves. 4. Welding points are prone to breakage during the wave pressing of steel wire, but the related losses are usually low. Since it is difficult to locate welding points in water tanks, it is not required to remove welding points, but only to remove welding points from products processed by other technical drawing methods.
