摘要： A method of enhancing the corrosion resistance of an austenitic steel includes removing material from at least a portion of a surface of the steel such that corrosion initiation sites are eliminated or are reduced in number relative to the number resulting from processing in a conventional manner. Material may be removed from the portion by any suitable method, including, for example, grit blasting, grinding and/or acid pickling under conditions more aggressive than those used in conventional processing of the same steel.
