标准范围

ISO 3506-2:20 09规定了由奥氏体、马氏体和铁素体钢级耐腐蚀不锈钢制成的螺母在10°C至35°C的环境温度范围内进行测试时的机械性能。在较高或较低的温度下，性能会有所不同。ISO 3506-2:20 09适用于螺母:-公称螺纹直径d≤39毫米；-直径和螺距符合ISO 68-1、ISO 261和ISO 262的三角形ISO公制螺纹；-任何形状；-具有ISO 272中规定的平面宽度；-标称高度m≥0.5 d。它不适用于需要锁定能力和可焊性等特性的螺母。

ISO 3506-2:2009 specifies the mechanical properties of nuts made of austenitic, martensitic and ferritic steel grades of corrosion-resistant stainless steels, when tested over an ambient temperature range of 10 °C to 35 °C. Properties vary at higher or lower temperatures.ISO 3506-2:2009 applies to nuts:- with nominal thread diameter d ≤ 39 mm;- of triangular ISO metric threads with diameters and pitches in accordance with ISO 68-1, ISO 261 and ISO 262;- of any shape;- with width across flats as specified in ISO 272;- with nominal heights m ≥ 0,5 d.It does not apply to nuts requiring properties, such as locking abilities and weldability.
