ISO 6931的本部分规定了冷拔设备中常用的不锈钢等级 以直径不超过10.00mm的圆形横截面钢丝的形式进行处理，用于生产 弹簧和弹簧零件暴露在腐蚀作用下，有时温度略有升高 （见附件A）。 ISO 16143-2涵盖的某些钢种也用于弹簧，尽管程度要小得多。 在这种情况下，机械性能（抗拉强度等）将由买方商定 和供应商。同样，直径介于10,00 mm和15,00 mm之间的可根据 ISO 6931本部分的规范，在这种情况下，双方将商定所需的机械设备 特点。 除了ISO 6931本部分的规范外，还包括 ISO 404适用。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of ISO 6931 specifies the grades of stainless steels which are generally used in the cold drawn condition in the form of wire of circular cross-section up to 10,00 mm in diameter, for the production of springs and spring parts exposed to corrosive effects and sometimes to slightly increased temperatures (see Annex A). Certain steel grades covered by ISO 16143-2 are also used for springs, although to a much lesser extent. In these cases, the mechanical properties (tensile strength, etc.) will be agreed between purchaser and supplier. Similarly, diameters between 10,00 mm and 15,00 mm can be ordered according to the specifications of this part of ISO 6931, in which case the parties will agree upon the required mechanical characteristics. In addition to the specifications of this part of ISO 6931, the general technical delivery requirements of ISO 404 are applicable.All current amendments available at time of purchase are included with the purchase of this document.
