【Abstract】 The test method of weak magnetic property of cold heading wire made of austenitic stainless steel used for producing screws to support the electronic tube is investigated.The internal controlled targets for test are put forward through examining austenitic stainless steel ML0Cr18Ni9Cu3 specimens by current impact test,and test results are analyzed and discussed.The results show that testing weak magnetic materials with current impact is reliable in data,is simple and convenient in method,can meet the needs for engineering using,and it can be regarded as basis to evaluate weak magnetism of steel wire.更多还原
