Table 2A & tABLE 5A of ASME SEC IID

[212197]

As per "GUIDELINE ON LOCATING MATERIALS IN STRESS TABLES, AND
IN TABLES OF MECHANICAL AND PHYSICAL PROPERTIES" given in ASME SEC. IID,

Table 2A is to be used for class 1 equipment of ASME SEC. VIII DIV 2.

Table 5A is to be used for ASME SEC. VIII DIV 2..

So if equipment is class 1, can I use Table 5A instead of using 2A?

My understanding is that :
1.when equipment is class 2, Table 5A is to be used.
2.when equipment is class 1, Table 2A is to be used.

Experts to comment.

No.

Correct.

Note that Table 2A/B does not go into the creep regime. There is a Code Case under construction that will correct that issue.
