•ʻO ka ikaika kiʻekiʻe, ka paʻakikī haʻihaʻi maikaʻi, nā ʻano mīkini transverse a me ke kūpaʻa ʻana i ka corrosion koʻikoʻi i loko o ke kai moana.
•Weldability: Ma o ka hoʻoheheʻe ʻana i ke kinoea inert, me ka hoʻohana ʻana i ka hapa nui o nā kaʻina hana wili, me ka wili plasma,electron beam wiliwili, A argon shielding kinoea ua makemake.
Hoʻohana nui ʻia i ka aerospace, nuklea reactors a me ka petrochemical a me nā māla ʻē aʻe, e like me nā mea hoʻopili poʻo anu a
ka mīkini, nā ʻāpana mokulele, nā ʻāpana reactor a me ka petrochemical equipment.
