Could anyone tell me which part of the PSV (pressure safety valve or pressure relief valve) must conforms to Section II listed material?

Is it all pressure bearing parts must be Section II listed material?

Thanks.

ASME Sec I requires that the body and yoke(bonnet) be made from ASME Sec II materials, the nozzle and disk must be made from either ASME sec or equivalent, which allows the vendor to use many different materials for the steam severe service.
