Most forms of stainless steel are subject to acid corrosion. As a tomato product, ketchup is acidic and probably should not be stored in stainless steel. Ketchup is usually stored in glass or plastic containers, which are usually less costly than stainless steel, so there is no reason to consider using stainless steel except in bulk manufacturing situations.
