pitting corrosion, and because of the unpredictability of the perfor- 

 mance of stainless steels in seawater, they can be recommended for 

 seawater applications only when adequately protected. At least one, 

 and usually more, specimens of each of the other alloys exhibited cor- 

 rosion in the nature of pitting, tunneling or crevice corrosion suf- 

 ficient to make the use of the alloy in seawater applications at least 

 questionable. 



If, because of its mechanical or magnetic properties, it is 

 desirable to use a particular stainless steel in seawater application, 

 provision must be made for its protection.
