	SPECIAL RECOMMENDATIONS

Special Recommendations

For 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.
