Hōʻike huahana
Aia ka Ti o 321 stainless steel ma ke ʻano he mea hoʻokūpaʻa, akā he kila ikaika ia, ʻoi aku ka maikaʻi ma mua o 316L. ʻO 321 ke kila kila maikaʻi ke kūʻē i ka abrasion i loko o nā waikawa organik a me nā ʻakika inorganic o nā ʻokoʻa like ʻole a me nā mahana, ʻoi aku hoʻi i ka media oxidizing, kahi i hoʻohana ʻia no ka hana ʻana i nā pahu wai-kūpaʻa a me nā mea paʻa a me nā laina paipu.
ʻO 321 ke kila kila he austenitic stainless steel alloy i loaʻa ka nickel (Ni), chromium (Cr) a me ka titanium (Ti). Hōʻike ia i nā waiwai like me 304 stainless steel, akā ʻo ka hele ʻana o ka titanium e hoʻonui i kona kūpaʻa corrosion ma nā palena o ka palaoa a hoʻonui i kona ikaika i nā wela kiʻekiʻe. Hoʻopili maikaʻi ka hoʻohui ʻana o ka titanium i ka hoʻokumu ʻana o ka chromium carbide i loko o ka alloy.
ʻOi aku ka maikaʻi o ke kila kila 321 kiʻekiʻe kiʻekiʻe. He kūpono ia no nā ʻāpana wili i hoʻohana ʻia i ka wela kiʻekiʻe.

FAQ
Q1: Pehea e pili ana i nā uku hoʻouna?
Hoʻopili ʻia nā kumukūʻai hoʻouna e nā kumu like ʻole, e like me ke ʻano hoʻouna. ʻO Express ka wikiwiki, akā ʻoi aku ka pipiʻi. ʻO ka ukana kaʻa ka mea i koho ʻia no ka hoʻouna ʻana i nā mea nui, ʻoiai ʻoi aku ka lōʻihi.
Q2: He aha kāu mau kumukūʻai?
E ʻoluʻolu e ʻoluʻolu e loli kā mākou kumukūʻai ma muli o ka lako a me nā kumu kūʻai like ʻole. I mea e hāʻawi ai iā ʻoe i ka ʻike kumu kūʻai pololei loa a me ka manawa hou, noi mākou iā ʻoe e hoʻokaʻaʻike mai iā mākou i hiki iā mākou ke hoʻouna iā ʻoe i kahi papa inoa kumukūʻai hou. Mahalo iā ʻoe no kou hoʻomaopopo ʻana.
Q3: Loaʻa iā ʻoe kahi helu kauoha liʻiliʻi?
No ka ʻike hou aku e pili ana i nā kauoha liʻiliʻi no nā huahana honua kikoʻī, e ʻoluʻolu e kelepona iā mākou.
