abstract: Material selection is very important for ship design and performance, especially for propeller shafts. Stainless steel 316L is commonly chosen for its corrosion resistance as a propeller shaft material. Although corrosion resistant, stainless steel 316L is still susceptible to pitting corrosion. Given that the shaft operates continuously while the ship is in operation, the potential for material damage cannot be avoided. This study aims to analyze the effects of quenching and partitioning on the mechanical properties, corrosion resistance, and microstructure of stainless steel 316L. The research process involved austenitization at 1000°C, initial quenching at 250°C, followed by partitioning at temperatures of 350°C, 425°C, and 500°C for 10 minutes, and final quenching. The testing was conducted using impact testing and electrochemical testing in NaCl medium with varying concentrations. The results of the study indicate that quenching and partitioning treatments can enhance the toughness of stainless steel 316L as the partitioning temperature increases compared to untreated samples, from 1.34 J/mm² to 1.85 J/mm². This increase in toughness is attributed to the fraction of retained austenite phase in the microstructure, which continues to increase with partitioning temperature, reaching 45.81%, 46.93%, and 49.83%. However, quenching and partitioning did not significantly improve corrosion resistance against higher NaCl concentrations due to grain size growth and the presence of retained austenite and martensite phases, which are more electrochemically active, making them more susceptible to chloride ion attack in NaCl solutions. Based on pitting potential, no indications of pitting corrosion were found. This study provides important insights into optimizing heat treatment to enhance mechanical properties and understanding the limitations in improving the corrosion resistance of 316L stainless steel, making it relevant for maritime applications.
