X12CrMoWVNbN-10-1-1   (EN No. 1.4906) is a high-alloy martensitic creep-resistant steel used in turbines and 

high-temperature service. It is not listed in ASME Sec IX QW/QB-422; hence it is treated as an unassigned material. 

Based on composition (10% Cr-Mo-W-V-Nb), it is metallurgically comparable to P91/P92 steels and aligns closest 

with P-No. 5C. Under ISO15608 grouping this material falls under Group 10/Cr-Mo-V creep resistance steels.

Sridhar.
