1.1本规范涵盖100级热处理合金钢链，用于吊索、提升组件和负载绑定等应用。 笔记 1-本规范不包括用于凹轮应用的合金钢链条。 1.2本规范是用于以下部件的100级链条的性能标准: − 20和400 ° F[ − 29和205 ° C] 。在该范围以外的温度下使用时，应联系链条制造商。 1.3等级名称为 1. / 10 最小断裂强度（单位:牛顿）除以链条标称横截面积（单位:平方毫米）的两倍。 1.4以国际单位制或其他单位表示的数值应单独视为标准值。 每个系统中规定的值可能不是精确的等效值；因此，每个系统必须相互独立使用，不得以任何方式组合值。

1.1 This specification covers Grade 100 heat-treated alloy steel chain for such applications as slings, lifting assemblies, and load binding. Note 1—This specification does not cover alloy steel chain for pocket wheel applications. 1.2 This specification is a performance standard for Grade 100 chain used between − 20 and 400 ° F [ − 29 and 205 ° C]. The chain manufacturer should be contacted for use at temperatures outside this range. 1.3 The Grade designation is 1 / 10 of the minimum breaking strength in newtons divided by two times the nominal cross-sectional area of the chain in square millimetres. 1.4 The values stated in either SI units or in other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.
