Wehewehe: ʻO Ni307-3 kahinikalaʻElekode i hoʻokumu ʻia me ka uhi sodium haʻahaʻa-hydrogen. E hoʻohana i ka DCEP (elekode au pololei maikaʻi). Loaʻa iā ia ke kūpaʻa maikaʻi no ka mea aia ka wili i kahi nui o ka manganese, niobium, a me nā mea hoʻohuihui ʻē aʻe.

Hoʻohana: Hoʻohana ʻia no ka hoʻopili ʻana onikala-chromium-hao alloys (e like me UNS N06600) a me ka ʻili o ke kila. ʻAʻole kiʻekiʻe ka mahana hana ma mua o 480 ° C, a maikaʻi ke kūpaʻa o ka māwae. Kūpono no ka hoʻopili ʻana i ka ipu hao atomika a me ka pahu kemika.
