Just to share with all, Austenitic SS grades such as SS304, SS321, SS347
having Molybdenum content less than 2% are highly susceptible to Stress
Corrosion Cracking at ambient temperatures and offshore environment.
Woodside Petroleum have banned their use on their offshore platforms based
on past performance.

Subject: [PipingDesign] New Current Interesting Link: Stainless Steel
304 vs. 304L. Have you ever wondered what the difference is in this spec? This site explains it all.
Please visit the Piping Design Central main page for the current interesting link.

<<Stainless steels are primarily used when corrosion or oxidation is a problem. The function that they perform cannot be duplicated by other materials for their cost. Over 50 years ago, it was discovered that a minimum of 12% chromium would impart corrosion and oxidation resistance to steel. Hence the definition “Stainless Steels”, are those ferrous alloys that contain a minimum of 12% chromium for corrosion resistance. This development was the start of a family of alloys which has enabled the advancement and growth of chemical processing and power generating systems upon which our technological society is based.>>
