This Standard replaces YB/T 5343-2009 "Steel Wire for Ropes"; compared with YB/T 5343-2009, the main changes are as follows. - The standard name "Steel Wire for Ropes" is revised as "Steel Wire for Ropes". - It is specified that this Standard is applicable to smooth and coated steel wires with circular cross sections for all kinds of steel wire ropes (excluding steel wire ropes for elevator). - The classification is according to the surface state, use, nominal diameter and nominal tensile strength of the steel wire. - The nominal diameter range of the steel wire is expanded to 0.08mm≤d≤6.00mm from the original 0.15mm≤d< 4.4mm. - 0.08mm≤d< 0.20mm and tolerance ±0.005mm are added in the nominal diameter column of Table 1 Diameter Tolerance; the original 0.15mm≤d< 0.30mm and 0.30mm≤d< 0.60mm are modified to be 0.20mm≤d< 0.40mm and 0.40mm≤d< 0.60mm; d< 0.40mm Level A coating tolerance is deleted. - The nominal tensile strength given by use in Table 2 is modified to be by surface state, nominal diameter of the steel wire and use purpose (important use in Table 2, general use in Table 3). For important use smooth and Level B’s nominal tensile strength < 4.0mm, 2160MPa is added; the nominal tensile strength of 1960MPa is increased from ≤4.4mm to < 5.4mm. For the nominal tensile strength < 0.2mm of general use smooth and Level B coated steel wire. 2000MPa, 2500MPa, 3000MPa, 3500MPa are added. 1180MPa of nominal tensile strength for general use is added. The nominal tensile strength corresponds to the nominal diameter of the steel wire; different steel wire diameters correspond to different nominal tensile strengths. - For steel wires with diameter less than 0.2mm, the tolerance of the nominal tensile strength shall be negotiated by both parties. - The minimum number of torsion and the minimum number of repeated bending for the expanded steel wire diameter and the increased nominal tensile strength in Table 5 ~ Table 8 are given. The number of repeated bending of the steel wire with diameter greater than 5.0mm shall be negotiated by both parties. - 5.6 “Other requirements” is canceled, the contents of this clause are revised to "Note. The number of repeated bending and the number of torsion of other nominal tensile strengths shall be negotiated by both parties" and are included in the corresponding Table 5 ~ Table 8. - 5.7 "Quality of zinc coating" is revised to be "Coating quality". - 6 "Test method" is revised to be "Inspection and test". - 6.1 Test items, methods and sampling positions are divided into 6.1 Inspection and 6.2 Test; the test items are divided into 3 items - diameter, ellipticity, shape; the surface quality is included into Table 11, and the inspection methods and quantity are given. 6.2 Test items, methods and sampling positions are included into Table 12. - 6.3 Sampling quantity is listed in a single row. It is stipulated that the number of samples shall be taken according to the number of each batch of steel wires; the sampling quantity and determination rules are given in Table 13. The calculation method of the number of each batch of steel wires is given in Annex A. This Standard was proposed by China Iron and Steel Industry Association. This Standard shall be under the jurisdiction of National Steel Standardization Technical Committee (SAC/TC183). Drafting organizations of this Standard. Ansteel Wire Rope Co., Ltd., Guizhou Wire Rope Incorporated Company, Hubei Fuxing Science and Technology Co., Ltd., China Metallurgical Information and Standardization Institute.
