There are stainless steel and stainless steel. In certain very specific environments, certain stainless steel grades do not hold up even though they are capable of withstanding other "very difficult conditions" of corrosion. The anecdote, a local craftsman who uses submerged stainless steel cables for special boats has no problem in the Atlantic Ocean .... these same cables do not hold for the same use in the Pacific. He had to change the shade of stainless steel so that it always works whatever the ocean / sea.
