[MW:9445] RE: 9444] Tube sheet

Nuclear Steam generator involves an extensive use of Ni-Cr-Fe alloys,
predominantly to mitigate IGSCC and other forms of EACs(environmental
assisted cracking).

Which grade of inconel cladding is specified in the steam generators and
what's the tube sheet material(20MoNi55 or others).

Could you elaborate a bit more.

Thanks.

Dear all,

Why we are using inconel cladding for tube sheet used for fabrication of
steam generator?
