ʻO ke kūpaʻa ʻino a me ke kaiapuni noi nui: ʻO 904L kahi ʻano o ka austenitic stainless steel me ka haʻahaʻa kalapona haʻahaʻa a me ka metala alloying kiʻekiʻe, i hoʻolālā ʻia no nā kūlana corrosion paʻakikī. ʻOi aku ka maikaʻi o ka corrosion ma mua o 316L a me 317L, a noʻonoʻo i ke kumukūʻai a me ka hana, a he kiʻekiʻe ke kumu kūʻai. 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 ʻino maikaʻi loa i ka corrosion stress, pitting corrosion a me ka crevice corrosion i hoʻokumu ʻia e ka chloride ion, a he kūpaʻa maikaʻi i ka corrosion intergranular. I loko o ka pae hoʻonaʻauao o 0-98%, hiki ke kiʻekiʻe ka mahana o 904L e like me 40 ℃. Ma ka laulā o 0-85% phosphoric acid, maikaʻi loa kona kūpaʻa ʻana. I loko o ka ʻenehana phosphoric acid i hana ʻia e ke kaʻina wai, ʻoi aku ka ikaika o nā haumia i ka pale ʻana i ka corrosion. I nā ʻano like ʻole o ka phosphoric acid, ʻoi aku ka maikaʻi o ke kūpaʻa corrosion o 904L ma mua o ke kila kila maʻamau. I loko o ka ikaika oxidizing nitric acid, ʻoi aku ka haʻahaʻa o ka corrosion o ke kila 904L ma mua o ke kila kila kiʻekiʻe me ka molybdenum. I loko o ka waika hydrochloric, ua kaupalena ʻia ka hoʻohana ʻana o 904L i kahi haʻahaʻa haʻahaʻa o 1-2%. Ma 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. I loko o ka chloride solution, kona ikehu pale corrosion. 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 corrosion koʻikoʻi i loko o kahi kaiapuni waiwai chloride ke kiʻekiʻe ka mahana ma mua o 60 ℃. Hiki ke hoʻemi ʻia ka sensitization ma ka hoʻonui ʻana i ka ʻike nickel o ke kila kila. Ma muli o kona kiʻekiʻe nickel maʻiʻo, 904L he kiʻekiʻe koʻikoʻi koʻikoʻi corrosion māhā kū'ē i ka chloride solution, concentrated hydroxide solution and hydrogen sulfide rich environment.
