The 2Cr15Mn15Ni2N austenitic diamagnetic stainless steel was a high-performance diamagnetic stainless steel.In order to meet the high diamagnetic requirements of parts,the effect of solid solution insulation temperature and in-sulation time on the diamagnetism of 2Cr15Mn15Ni2N austenitic diamagnetic stainless steel was studied by using diamagnet-ic testing,metallographic structure analysis,and grain size testing.As a result,it was found that by using 1 120 ℃ solution and extending the heat preservation time,when the grain size of 2Cr15Mn15Ni2N anti magnetic stainless steel grew to level 6 and the grain size was uniform,the diamagnetism level reached≤Ⅱ,which met the technical requirements of the product and solved the problem of insufficient solid solution anti magnetism.The production process control parameters were pro-posed,which provided reference for the treatment of similar problems in the future.
