4 Size, shape and weight
4.1 The nominal diameter range of wire rods is: 4.5mm~40.0mm.
4.2 The allowable diameter deviation and out-of-roundness of wire rods shall comply with the provisions of GB/T 14981-2009 (when the diameter is 4.5mm, it shall be in accordance with the provisions for 5mm) and the accuracy is in accordance with level B. Agreed by the supplier and the purchaser and
indicated in the contract, delivery may be in accordance with the accuracy for other levels.
4.3 Weight of wire rods
4.3.1 Each coil of wire rods consists of one piece. The weight of wire rods shall not be less than 1000kg. The following cases allow delivery but the total quantity of wire rods shall not exceed 5% of the number of coils per batch (when it is less than 2 coils, it is allowed to have 2 coils).
a) The wire rods that consist of one piece and the weight is less than 1000kg but greater than 800kg;
b) The wire rods that consist of two pieces but the coil weight is not less than 1000kg, the weight of each wire rod is not less than 300kg and there is an obvious identifier.
4.3.2 As required by the purchaser and agreed by both parties, the wire rods with other special coil weight requirements can be provided.
5 Technical requirements
5.1 Designation and chemical composition
5.1.1 The designation and chemical composition (melting analysis) of steel shall comply with the provisions of Table 1 ~ Table 5. As required by the purchaser and agreed by both parties, wire rods of other designations and chemical composition requirements can be provided. See Annex A for the control on designations between this Standard and original standard. See Annex B for the main usage of designations specified in this Standard. See Annex C for the control between designations of this Standard and some foreign designations. 5.1.2 The allowable deviation of chemical composition of finished wire rods shall comply with the provisions of GB/T 222. Only when it is required by the purchaser and indicated in the contract, the manufacturer shall carry out the analysis on chemical composition of finished products. Report the analysis results of finished products in the quality certificate.
