GH39 High Temperature Alloy Rod Plate ASTM Fatigue Resistance
KX GH39 Light Rod Plate Structural Operating Temperature Range For High Temperature Alloy
Product Description and Application
GH39 is also known as "KN602, shed osan 75 manas (Russia), and GH3039.
GH39 is a single-phase Austenitic solid solution reinforced alloy with moderate thermal strength and good thermal fatigue properties below 800℃ and good oxidation resistance below 1000℃. Long-term use with stable structure and has good cold formability and welding performance. It is suitable for aero engine combustion chamber and afterburner parts used for a long time below 850℃. The alloy can produce sheet, bar, wire, pipe and forgings.
