Abstract

Martensitic stainless steels were usually used for turbine blade. Their properties can be improved in various ways, such as by heat treatment. This paper reports the influences of tempering temperature and holding time in various concentration and temperature of NaCl solution on corrosion rate of the modified 13Cr martensitic stainless steels. Samples were austenized at 1050⁰C for 1 hour followed by oil quenching. The austenized sample were tempered at 600⁰C, 650⁰C, and 700⁰C for 1, 3, and 6 hours. All tempered specimens were immersed in 20% NaCl concentration for 120 hours and tempered specimen at 700⁰C for 6h was prepared for another corrosion test. Samples were immersed in different concentration of NaCl solution 3.5%; 10%; and 20% at room temperature, 60⁰C, and 80⁰C. Increasing temperature and concentration of solution will lead to corrosion rate increased. However, corrosion rate slightly decreases at higher temperature due to dissolved oxygen was decreased.
