Nā Lepili Huahana

Hoʻopili ʻia ka mea NiCr8020 me ka helu mea 2.4869 ma ke ʻano o nā ʻāpana, nā pepa, nā paipu a me nā uea no nā ʻāpana kūkulu umu a me nā alakaʻi hoʻomehana.

He mea hoʻohuihui alakaʻi hoʻomehana nickel-chromium ia no nā mahana hana a hiki i 1150 °C a loaʻa pinepine nā mea hoʻohui o nā honua laha no ke kūpaʻa kiʻekiʻe i ka oxidation, ʻoi aku hoʻi me nā hana hoʻololi pinepine a i ʻole nā ​​​​​​loli wela ākea.

ʻO ke kūpaʻa ʻana i ka palaho lewa ma 20 °C he kiʻekiʻe a hiki i ka mahana hana kiʻekiʻe. ʻO ke kūpaʻa ʻana i ka ea a me nā kinoea ʻē aʻe i loaʻa ka oxygen a me nā kinoea oxygen haʻahaʻa i loaʻa ka naikokene he kiʻekiʻe nō hoʻi, akā haʻahaʻa ia i nā kinoea oxidizing a me nā kinoea hōʻemi i loaʻa ka sulfur.

Kiʻekiʻe ke kūpaʻa ʻana i ke kalapona. Noi ʻia no nā umu uila ʻoihana, nā umu enameling, nā lako hale, nā mea hoʻomehana wahi mālama pō.
