摘　　要：304不锈钢系奥氏体为主的无磁性或低磁性不锈钢,但加工变形后亚稳态奥氏体会发生相变产生马氏体组织,形成较强的磁性。通过对304不锈钢波纹管的磁滞损耗进行测试,对测试样品进行金相观察,研究了304不锈钢相变的情况。同时对样品材料进行磁滞回线测试,研究了波纹管的磁滞损耗情况。304 stainless steel is usually non-magnetic or low magnetic austenitic stainless steel,which may convert to martensite and became magnetic when mechanical deformed. the Hysteresis loss of The stainless steel corrugated pipe was tested,the metallographic and hysteresis loop of the steel was learned.
