Just wondering what everyone has found in terms of the difference between the 2 grades of stainless. I have been using 304L without any corrosion and any noticable ill effects. Has anyone done any testing between the outputs between the 2? I wonder if the 316L has different resistance ( like maybe lower) so that it would better output. 304L is way cheaper so if there really isn't any difference then why not use 304L? Something to think about.
