FLUID SYSTEMS COMPATIBILITY
Gaseous Oxygen (GOX)Meets the mechanical impact requirements. No batch test required
Liquid Oxygen (LOX)Meets the mechanical impact requirements. No batch test required.
Nitrogen Tetroxide (N2O4)SCC susceptibility is low and no fluid decomposition
Hydrazine (HDZE)SCC susceptibility is low and no fluid decomposition
SPECIAL RECOMMENDATIONS
Special RecommendationsFor precipitation hardened parts, heating above the precipitation temperature may result in susceptibility to intergranular and stress corrosion. · The room-temperature aged conditions may become susceptible to intergranular corrosion if the alloy is heated above 65°C.
