ʻAno waiwai opaipu hale
He nui nā kumu hoʻololi e hōʻike ana i nā hiʻohiʻona erosion waena, ʻo ia hoʻi nā huahana kemika a me kā lākou ʻike ʻana, nā kūlana o ka lewa, ka mahana, ka manawa, no laila inā ʻaʻole maopopo i ke ʻano maoli o ka waena, e hoʻohana i nā mea, paʻakikī ke koho ʻana i nā mea.Eia naʻe, hiki ke hoʻohana ʻia nā alakaʻi ma ke ʻano he koho:
304 i loko o ka hoʻohana waiwai.Hiki i nā hale ke kū i ka ʻino maʻamau, hiki ke kū i ke ʻano o ka hoʻoheheʻe ʻana i ka meaʻai (loaʻa i loko o ka ʻakika concentrated akā ʻike ʻia ka wela a me ka chloride maʻiʻo), hiki ke kūʻē i nā pūhui organik, nā mea pena, a me nā ʻano mea like ʻole.
304L (carbon haʻahaʻa) me ka maikaʻi kū'ē i ka nitric acid, a me ka lōʻihi ma waena o ka mahana wela a me ka sulfuric acid, i hoʻohana 'ia e like me ka wai i loko o ke kinoea pahu, hoʻohana 'ia no cryogenic lako (304N), ke koena o ka consumer lako huahana, lumi kuke lako, lako halemai, mea lawe, lako lawe wai.
Loaʻa i ka 316 kahi nickel ma mua o 304, a he 2%─ʻO 3% molybdenum, ka pale ʻana i ka corrosion ma mua o ka Type 304, ʻae ʻia i ka makemake o nā wahi kūikawā o ka erosion i hana ʻia e ka media chloride.Ua hoʻohana ʻia ʻo 316 ma ke ʻano he mīkini pulp sulphite hoʻomohala, no ka mea ʻo ia ka pūhui sulfate paʻa.Eia kekahi, ua hoʻonui ʻia kona hoʻohana ʻana e mālama i ka nui o nā huahana kemika i ka ʻoihana hana.
317 i loko o 3% -4% molybdenum (kiʻekiʻe kiʻekiʻe i loko o kēia pūʻulu loaʻa pū kekahi), a loaʻa ma mua o 316 mau ʻano chromium, ʻoi aku ka kiʻekiʻe o ke kū'ē i ka pitting corrosion a me ka crevice corrosion hana.
430 haʻahaʻa ma mua o ka 304 alloy content, hoʻohana ʻia i loko o kahi lewa mahana i hoʻonani ʻia me ka hoʻohana ʻia ʻana, hiki ke hoʻohana ʻia i ka waikawa nitric a me nā mea hana meaʻai.
ʻO 410 he ʻekolu hoʻohana maʻamau o ke kila kila ma ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, pono ʻoe i ka ikaika a me ke kūpaʻa corrosion me nā ʻāpana haʻahaʻa kiʻekiʻe i hoʻohana ʻia, e like me nā ʻāpana paʻa.410 i loko o kahi lewa mahana, ka wai, ke kinoea a me nā huahana kemika i loko o ka pāpaho he nui ke kū'ē corrosion.
2205 ma mua o ka 304 a me ka 316 kiʻekiʻe, no ka mea, he ikaika kiʻekiʻe ke ʻano o kāna paipu chloride stress corrosion cracking.
