ẸYA Ọja
GH738 ni a nickel-orisun ga-otutu alloy lile nipa γ' alakoso ojoriro, pẹlu ti o dara gaasi ipata resistance, ga ikore agbara ati rirẹ-ini, ti o dara ilana plasticity ati idurosinsin agbari. Ti a lo ni lilo ni awọn ẹya yiyi ẹrọ ọkọ ofurufu, lilo iwọn otutu ko ga ju 815 ℃. O le ṣe agbejade tutu ti yiyi ati awọn awo ti yiyi gbigbona, awọn paipu, awọn ila, awọn okun onirin, awọn ayederu, awọn simẹnti ati awọn fasteners.
Ohun elo ọja
Awọn enjini ọkọ ofurufu, awọn turbin gaasi ẹrọ, awọn abẹfẹlẹ turbine ati awọn disiki turbine ati awọn ẹya iyipo miiran.
