EN 10216-5 Chemical Compositions of stainless steels
EN 10216-5 2004 is the European Standard for Stainless Steel Seamless Tubes for pressure purposes. It covers the following categories:
Austenitic corrosion resisting steels (21 grades)
Austenitic creep resisting steels (12 grades) including some which do not appear in EN 10302 also for creep resisting steel
Austenitic-ferritic duplex corrosion resisting steel (6grades)
