ʻO 904L kahi haʻahaʻa kalapona haʻahaʻa, kiʻekiʻe alloying austenitic stainless steel i hoʻolālā ʻia no nā kaiapuni corrosive koʻikoʻi.ʻOi aku ka maikaʻi o ka corrosion ma mua o 316L a me 317L, ʻoiai ke kaupaona nei i ke kumukūʻai a me ka hana, a ʻoi aku ka maikaʻi o ke kumukūʻai.Ma muli o ka hoʻohui ʻana o 1.5% keleawe, loaʻa iā ia ke kūpaʻa corrosion maikaʻi loa no ka hōʻemi ʻana i nā waikawa e like me ka sulfuric acid a me ka phosphoric acid.Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka corrosion stress, pitting corrosion, a me ka corrosion crevice i hoʻokumu ʻia e nā ion chloride, a maikaʻi ke kūʻē i ka intergranular corrosion.I loko o ka sulfuric acid maʻemaʻe me ka pae koʻikoʻi o 0-98%, hiki ke piʻi ka mahana hoʻohana o 904L a hiki i 40 degere Celsius.I loko o ka waika phosphoric maʻemaʻe me ka pae hoʻonaʻauao o 0-85%, maikaʻi loa kona kūpaʻa corrosion.He hopena koʻikoʻi ka haumia i ka pale ʻana o ka phosphoric acid ʻoihana i hana ʻia e ka ʻenehana kaʻina hana.Ma waena o nā ʻano waika phosphoric a pau, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion ma mua o ke kila kila kila maʻamau.I loko o ka waika nitric oxidizing nui loa, ʻo 904L ka haʻahaʻa haʻahaʻa o ka corrosion i hoʻohālikelike ʻia me nā māka kila kila kila me ka molybdenum.I loko o ka waika hydrochloric, ua kaupalena ʻia ka hoʻohana ʻana o 904L i nā haʻahaʻa haʻahaʻa o 1-2%.Iloko o keia pae noonoo.ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion o 904L ma mua o ke kila kila maʻamau.ʻO ke kila 904L ke kūpaʻa kiʻekiʻe i ka pitting corrosion.ʻO kona kūpaʻa ʻana i ka crevice corrosion ma ka solution chloride.Maikaʻi nō hoʻi ka ikaika.ʻO ke kiʻekiʻe o ka nickel content o 904L e hōʻemi ana i ka nui o ka corrosion i loko o nā lua a me nā māwae.Hiki ke maʻalahi ke kila kila austenitic maʻamau i ka ʻinoʻino i loko o kahi kaiapuni i waiwai i ka chloride ma nā mahana ma luna o 60 degere Celsius.Ma ka hoʻonui ʻana i ka ʻike nickel o ke kila kila, hiki ke hoʻemi ʻia kēia sensitization.Ma muli o kona mau nickel kiʻekiʻe, hōʻike ʻo 904L i ke kūpaʻa kiʻekiʻe i ke koʻikoʻi i ka pohā ʻana o ka corrosion i loko o nā solution chloride, concentrated hydroxide solutions, a me nā kaiapuni waiwai i ka hydrogen sulfide.

ʻO ka ʻaila a me nā lako petrochemical, e like me nā reactors i nā lako petrochemical, ka mālama ʻana a me nā mea lawe no ka sulfuric acid, e like me nā mea hoʻololi wela, nā mea hoʻonaninani flue gas desulfurization, i hoʻohana nui ʻia i ke kino hale kiaʻi, flue, nā pani puka, nā ʻāpana kūloko, nā ʻōnaehana spray, etc. o ka absorption towers, scrubbers and fans in organic acid treatment system, seawater treatment device, seawater heat exchangers, papermaking oihana lako, sulfuric acid and nitric acid lako, acid production, etc. , pharmaceutical factory: centrifuges, reactors, etc., mea kanu mea'ai: soy sauce tanks, kuke waina, paakai pahu, lako a me na lole, 904L mea he kila kila no ka dilute sulfuric acid ikaika corrosive medium.

ʻO ka pā, ka ʻili, ka pā, ka uea, ka hoʻoheheʻe ʻana, ke koʻokoʻo maʻemaʻe, ka mea wili, ka flange, a me nā mea ʻē aʻe, hiki ke hana ʻia e like me ke kaha kiʻi.
