316 kila kohu ʻole vs Pahele 5 Titanium he mau mea maikai a elua, akā ua hoʻopaʻa ʻia lākou no nā mea nui ʻenehana.
316 ʻO ke kila kuhiliʻole ka mea maʻamau a me ka hana ʻana-aloha i ka huila: Hāʻawi ia i ka pale chloride ikaika, maikaʻi loa, maikaʻi maikaʻi, a me ka oolea kiekie loa.
Kumu 5 ʻO ka titanium ka mea hana kiʻekiʻe kiʻekiʻe: ua oi aku ka mama, ʻoi aku ka ikaika, ʻoi aku ka paʻa o ka dimensionally me nā loli wela, a ʻoi loa ka maikaʻi ma ka aerospace a me nā noi i ʻike ʻia i ke kai.
ʻO ka hoʻoholo maoli ʻaʻole inā ʻoi aku ka maikaʻi o ka mea hoʻokahi.
ʻO ia ka manaʻo o ka hoʻolālā e ka ʻoʻoleʻa, ʻino i ka lawelawe chloride, hana maʻalahi, a me ke kumu kūʻai pono—nā kūlana e makemake ana i ka 316—a i ʻole ma ka hoʻemi kaumaha, ikaika kiʻekiʻe, a me ka hana pono ma lalo o nā kūlana koi—nā kūlana e makemake i ka titanium Ti-6Al-4V.
ʻO ia ke ala maʻemaʻe e heluhelu ai i ka hoʻohālikelike.

ʻO ka mea ikaika, 316 kila kila vs Papa 5 Titanium?
Kumu 5 ʻoi aku ka ikaika o ka titanium. 316 a 515 MPa ikaika tensile liʻiliʻi and 205 MPa liʻiliʻi liʻiliʻi, oiai Papa 5 hiki ke hoʻomohala e pili ana 1100 MPa ikaika loa i nā ʻāpana kūpono i mālama ʻia me ka wela.
ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion?
Aia ia i ke kaiāulu. 316 ʻoi aku ka ikaika e kūʻē i ka ʻinoʻino ʻana i ka lua a me ka crevice corrosion ma nā wahi chloride, ʻoiai ʻo Ti-6Al-4V titanium he kūpaʻa maʻamau maikaʻi loa i ka wai kai ma muli o kāna TiO₂ passive layer..
ʻOi aku ka maikaʻi no ka hoʻohana ʻana i ka moana?
Hiki ke hoʻohana ʻia nā mea ʻelua, akā no nā kumu like ʻole. 316 he koho kuhiliʻole ikaika no ka hoʻolaha ʻana i ka chloride,
oiai Papa 5 Kūleʻa kūʻē ka titanium i ka ʻino wai kai maʻamau a makemake pinepine ʻia inā ʻoi aku ka nui o ke kaumaha a me ka lōʻihi o ka wai kai..
ʻOi aku ka maikaʻi no ka aerospace?
ʻO ka papa Titanium 5 ʻo ia ka mea hoʻohui aerospace kūlohelohe no ka mea ua hui pū ʻo ia i ka haʻahaʻa haʻahaʻa me ka ikaika kiʻekiʻe a hoʻohana ʻia i nā ʻāpana compressor, nā ʻāpana mokulele, nā ipu koʻikoʻi, a me nā pahu pahu pahu.
He Papa 5 ʻoi aku ka maikaʻi o ka titanium 316?
ʻAʻole. 316 ʻoi aku ka ʻoʻoleʻa, maʻalahi ka hana ʻana, a ʻoi aku ka hana maʻamau i nā mea hana ʻino. ʻOi aku ka maikaʻi o Ti-6Al-4V inā ʻoi aku ke kaumaha a me ka ikaika kikoʻī i ka pilikia hoʻolālā.
