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.
