Section II Part D Allowables
(OP)
Anyone know the rules for determining allowables for a material not listed in Section II part D?
This is a high temperature Ni-Cr-Co alloy - Nimonic Alloy 263.
Thanks.

The ASME VIII Div 1 BPVC allows you to use any legitimate material fabricated for use in the pressure vessel industry, anywhere in the world (including China), provided that the Clause UG-10 and UG-11 requirements are met. Nimonic 263 material code is W 2.4650, UNS N07263; BS HR10, HR206, HR404; SAE AMS 5872; WL Nr. 2.4650; AFNOR NCK 20D; AECMA Pr EN 2199-2203, 2418.

If one wants to use a material for pressure retaining service, it must have allowable stress values listed in Section II, Part D OR submit a code case. If one wants to use a material for trim or non-pressure retaining this is different and UG-10 could be used provided the material conforms to a recognized specification or can be certified as being equivalent to a known material specification.
