There is not a straight forward answer. There are many grades
and variants of Stainless steel. The highest contributor to the
Anodic index of stainless steel is the amount of Chromium in the
different grades. Taking this into consideration, High Chromium
content Stainless Steel would have an Anodic index of around 0.50,
whiles the lowest grade stainless steel variants would have an
Anodic index of around 0.85.
