THE INFLUENCE OF HEAT TREATMENT ON MICROSTRUCTURE AND CORROSION RESISTANCE OF 13Cr-1Mo MARTENSITIC STAINLESS STEEL
Abstract
observation which was conducted by using an optical microscope and corrosion tests which were conducted by using 3,5% NaCl solution. The results show the evolution of microstructure in martensitic stainless steel 13Cr-1Mo after heat treatment. The microstructure formed consists of tempered martensite, delta ferrite, retained austenite, and carbides. The presence of carbides can also affect corrosion resistance, which will increase along with the increase of tempering temperature due to the increased content of Cr in the carbides. The highest value corrosion resistance was obtained at the austenitizing temperature of 1.050 ºC and tempering temperature of 600 ºC.
