ʻO Nickel Alloy GH4738 kahi hana kiʻekiʻe, nickel-based superalloy i hoʻolālā ʻia e ʻoi aku ka maikaʻi ma nā wahi koi loa. Me kona ikaika kiʻekiʻe, kūʻē kūʻokoʻa i ka oxidation a me ka corrosion, a me ke kūpaʻa kupaianaha i nā mahana kiʻekiʻe, kūpono ʻo GH4738 no nā noi i ka aerospace, ka mana hana, a me nā ʻoihana ʻē aʻe e koi ana i ka hana hilinaʻi ma lalo o nā kūlana koʻikoʻi. Hāʻawi kēia alloy i ke kūpaʻa creep maikaʻi a me ka ikaika luhi, e hōʻoia ana i ka lōʻihi o ka lōʻihi a me ka pono. E koho i ka Nickel Alloy GH4738 no kāu mau noi wela kiʻekiʻe koʻikoʻi a ʻike i ka hilinaʻi like ʻole a me ka hana.
