Abstract
Typical austenitic, ferritic and duplex stainless steels with different surface treatments were put to laboratory simulated seaside environment corrosion testing. Tests were measurement of pitting potential in 3% NaCl solution at room temperature, and corrosion under MgCl2 deposit at 40°C and 50% relative humidity, which is an accelerated seaside environment. Kelvin probe was used to study the surface properties of materials. Pitting potential in 3% NaCl, and simulated seashore atmospheric corrosion testing gave adequate data for evaluating corrosion of stainless steels under chloride particles. Kelvin probe was useful in corrosion monitoring on whether stainless steel was attacked or not by chlorides.
