| Description: Research carried out in about the last fifteen years in CREUSOT LOIRE INDUSTRIE laboratories shows that a strong addition of silicon to austenitic stainless steels of the 18/10 type has a favorable influence on resistance to transpassive intergranular corrosion. This type of corrosion develops particularly in very concentrated nitric environments (> 90 %) up to boiling point, also in strongly oxidizing nitric environments (oxidizing ions present such as : hexavalentchromic pentavalent vanadium - ferritic salts etc...). URANUS® S1 steel grade puts in a concrete form the results of research in this domain. Information provided by manufacturer. |
