Hi,
I'm a little confused by the requirements of EN 13445 paragraphs 8.4.2 and 8.4.3. For shells made in non austenitic steel the nominal elastic limit is given by R[sub]p0.2/T[/sub] but for austenitic steel it's the same value divided by 1.25.
Could anyone help with an explanation as to why the nominal elastic limit for austenitic materials are 80% less than the equivalent non-austenitic material please?
Additionally for duplex/super duplex materials should I consider them as austenitic or non-austenitic?
Thanks in advance
