Was the 15CrMo material removed in API 941?

I worked on a hydrogenation project for which a foreign party provided the process package; for the reactor, using 15CrMo material as specified by the process parameters would have been sufficient. However, the foreign party claimed that 15CrMo is not listed in the Nelson curve of API941. Does anyone have any evidence to support this claim?

15CrMO is a Chinese grade. . . It’s normal that there isn’t one in the API, right?

15CrMO is a low-alloy steel developed in China; its absence in API does not mean it cannot be used.

Isn’t 1Cr-0.5Mo in the Nelson curve of API941-2008 the same as 15CrMo?
