Hōʻike huahana
Ma hope o ka hoʻohui ʻana iā Ti ma ke ʻano he mea hoʻokūpaʻa, hōʻike ʻo 321 stainless steel i ka ikaika wela maikaʻi loa, ʻoi aku ka maikaʻi ma mua o ke kila 316L. Loaʻa iā ia ke kūpaʻa ʻaʻahu maikaʻi loa i nā ʻakika organik a me nā waikona inorganic ʻoiai ma nā ʻano ʻokoʻa a me nā mahana. Hoʻohui ʻia, ʻoi aku ka maikaʻi o ke kila kila kila Type 321 i nā kaiapuni oxidizing. He mea kūpono kēia no ka hana ʻana i nā moku kūpaʻa waika, nā linings a me nā paipu.
ʻO ka haku mele ʻana o 321 stainless steel e pili ana i ka nickel (Ni), chromium (Cr) a me ka titanium (Ti), ʻo ia ka austenitic stainless steel alloy. E like me 304 kila kila me nā waiwai like. Eia nō naʻe, ʻo ka hoʻohui ʻana o ka titanium e hoʻomaikaʻi i kona kūpaʻa corrosion ma nā palena o ka palaoa a hoʻonui i kona ikaika i nā wela kiʻekiʻe. ʻO ka hoʻohui ʻana o ka titanium e pale pono i ka hoʻokumu ʻana o ka chromium carbide i loko o ka alloy.
He waiwai maikaʻi loa ka 321 stainless steel e pili ana i ka haki ʻana o ke kaumaha kiʻekiʻe a me ke kūpaʻa kolo. ʻOi aku ka nui o kona mau waiwai mechanical ma lalo o nā kūlana wela kiʻekiʻe ma mua o ka 304 stainless steel. No laila, kūpono ia no nā noi welding e pili ana i nā ʻāpana e hana ana i nā wela kiʻekiʻe.

FAQ
Q1: Pehea e pili ana i nā uku hoʻouna?
Hoʻopili ʻia nā kumukūʻai hoʻouna e nā kumu he nui. Inā ʻo ka manawa ka mea nui, ʻo ka hāʻawi hōʻike ʻana ke koho maikaʻi loa, ʻoiai ma ke kumukūʻai kiʻekiʻe. No ka nui nui, ʻoi aku ka maikaʻi o ka lawe ʻana i ke kai, ʻoiai ʻoi aku ka lōʻihi. No ka loaʻa ʻana o kahi ʻōlelo hoʻouna pololei e noʻonoʻo ana i ka nui, ke kaumaha, ke ʻano a me ka huakaʻi, e ʻoluʻolu e kelepona mai iā mākou.
Q2: He aha kāu mau kumukūʻai?
E ʻoluʻolu e hoʻololi i kā mākou kumukūʻai ma muli o nā kumu e like me ka lako a me nā kūlana mākeke. No ka hōʻoia ʻana e loaʻa iā ʻoe ka ʻike kumu kūʻai pololei a me ka manawa hou, ke noi aku nei mākou iā ʻoe e hoʻopili pololei iā mākou. E hauʻoli mākou e hāʻawi iā ʻoe i kahi papa inoa kumukūʻai hou. Mahalo iā ʻoe no kou launa pū ʻana a me ka ʻike.
Q3: Loaʻa iā ʻoe kahi helu kauoha liʻiliʻi?
Inā makemake ʻoe i nā kikoʻī hou aku e pili ana i nā koi kauoha liʻiliʻi no nā huahana honua kikoʻī, e ʻoluʻolu e kelepona iā mākou. Eia mākou e kōkua iā ʻoe a hāʻawi iā ʻoe i ka ʻike e pono ai. E ʻoluʻolu e kelepona mai iā mākou ma kāu ʻoluʻolu.
