UNS K21590 Cold Drawn Pipe Hydrogen Attack Resistance
Why refinery buyers specify Grade P22 over lower-chromium grades for hydrogen service.
Nelson Curve Position
Above P11 / P12
2.25Cr-1Mo sits higher on the API 941 Nelson curve
Hydrogen Partial Pressure
Higher Tolerance
Withstands greater H₂ partial pressure before decarburization
Preferred For
Hydroprocessing
Hydrocrackers and high-temperature hydrogen circuits
When To Step Up
Consider P91
Where design pressure exceeds the P22 Nelson curve limit
