摘　　要：对4种不同合金成分的试样进行测试分析,确定电力节能金具的最佳合金成分。通过分析锰、铝、铬、稀土等元素在稳定的奥氏体无磁钢形成中的作用,再对其中2种试样进行磁性测试比较,最终,对由最佳合金试样制作的XGU-3W型悬垂线夹进行耗能测试。结果表明,新材料具有稳定的奥氏体金相结构,磁性小,且节能率达到92.8%。In order to determine the best alloy composition of the electric power energy saving fittings,this paper focused on four different alloy samples tested.By analyzing the effects of manganese,aluminum,chromium,rare earth elements in the formation of stable non-magnetic austenite,two group samples were undergo the magnetism tested and compared.Finally,XGU-3W suspension clamp which was made according to the best alloy composition was tested on energy-consuming.The results show that the new material had a stable austenitic metallurgical structure,small magnetism,and energy saving rate is about 92.8%.
