Abstract

In this research, the analysis of corrosion rate and hardness on stainless steel 304 and lateritic nickel steel in corrosive medium has been done. The lateritic nickel steel used has different Ni content of 0, 3, 4, 6, and 10%. The corrosion rate was calculated using the weight loss method while the hardness was measured by the Rockwell method. The test results showed that the corrosion rate was highest in samples immersed in the corrosive medium H2SO4 3.5% for 7 days, that is equal to 8.39 x 10-3 mm/year for the SS-304. For lateritic nickel steel, the highest corrosion rate occured in the sample with 0% Ni in corrosive medium H2SO4 3.5% which is equal to 50.85 mm/year. The hardness of the samples decreased after corrosion. The result of XRD analysis showed that SS-304 steel has an Fe-g (ferrite) and Fe-g (austenite) phase while the lateritic nickel steel has Fe phase. However, Ni phase was also formed in lateritic nickel steel with Ni content of 6% and Fe-g (austenite) phase in lateritic nickel steel with Ni content of 10%. The result of SEM characterization showed that the corrosion product formed is pitting corrosion with different hole diameter. The result of EDX analysis showed the presence of  elements of O, Na, and Cl on corroded samples in the corrosive medium NaCl 3.5%.
