Buyers pay for 316 and still see rust. Then installs slip and claims grow. So, I will show the details that stop seawater corrosion. SS316 usually resists chloride pitting better than SS304 in marine exposure. However, weld heat-tint, rough Ra, and crevices often trigger early rust. So, I specify SS316L plus ASTM A967 passivation steps […]
