P1 equivalence issues

P1 equivalence issues

(OP)
Greetings, I have some doubts about the equivalence of a S-355-J2,

Is S-355-j2 steel plate belong to 1.2 grouping of ISO 15608?

Is A572-Gr50 steel plate equivalent to a S-355-J2?

Based in the table 4.4 a of API 650 2013, is possible to say that all the materials in the group IVA are equivalents?

Based in the equivalence of grouping numbers showed in table QW/QB-422 of ASME IX, which indicates that an A572, A573 and A622 are grouped as P1 and equivalent to ISO 15608 subgroup 1.1, 1.2 and 11.1, it' possible to use a PQR for P1 steel pipe in P1 Plate welding, ?

thank´s a lot metengr.

RE: P1 equivalence issues

Just remember there is no "equivalence" between ISO materials ans ASME IX materials.
If it is not listed in ASME IX then it does not have a P number and is therefore classed as an unassigned material.
