    304N is not marine grade. It is 304 with a little extra nitrogen for hardness.

    Marine grade steels have molybdenum for chloride resistance like 316L.

      I was going to say that. 304 is the cheap “marine grade” sold at the hardware store that will rust. 316 is sold at the Chandelry and won’t rust.

      To put it another way, 304 is freshwater stainless, 316 is ocean grade.
