Effect of Heat Treatment on Microstructure and Mechanical Properties of 316LN Austenitic Stainless Steel As-cast
The effects of temperature and holding time on the change of ferrite content,morphology and mechanical property of 316LN austenitic stainless steel were studied.The results show that the content of ferrite decreases with the increase of solution temperature and solution time.The morphology gradually changes from skeletal shape into round blob-shaped and the hardness decreases gradually.
