GH4169 Papa
1. wehewehe:
ʻO GH4169 kahi kumu i hoʻoikaika ʻia i ka ua i hoʻopaʻa ʻia i ka alloy kiʻekiʻe me ka hana piha maikaʻi i ka mahana.
ka laulā o -253 650C ma ka home.
ʻO ka ikaika i hāʻawi ʻia ma lalo o 650C ke kūlana mua ma waena o nā alloys wela kiʻekiʻe deformed, a he maikaʻi ke kūpaʻa luhi, ka pale radiation,
ka pale ʻana i ka oxidation, ka pale ʻana i ka corrosion, a me ka hana maikaʻi a me ka hana wili.

5. Pono waiwai:
1) Ka ikaika wela kiʻekiʻe: GH4169 kiʻekiʻe-mehana alloy he maikaʻi loa ka ikaika wela kiʻekiʻe, hiki ke hana no nā manawa lōʻihi ma
nā kaiapuni wela kiʻekiʻe, a maikaʻi loa ke kūʻē i ka luhi.
2) Ke kū'ē i ka corrosion: ʻO ka GH4169 kiʻekiʻe-mehana alloy he maikaʻi ke kūpaʻa kino a hiki ke kū i ka waika ikaika, alkali, a me ka wela kiʻekiʻe.
nā kaiapuni hoʻokahe
3) Hiki i ka mīkini: GH4169 kiʻekiʻe-mehana alloy he machinability maikaʻi a hiki ke hoʻohana ʻia no ka forging, mālama wela, welding a me nā kaʻina hana ʻē aʻe.
6. Noi:
Hoʻohana nui ʻia ka GH4169 alloy kiʻekiʻe i ka aerospace, ka ikehu, a me nā māla kemika, e like me nā ʻāpana ʻenekini mokulele, nā ʻāpana keʻena puhi ahi, nā ʻāpana wahie nuclear power plant, etc.
