ʻO AISI 904L kila kila a i ʻole AISI 904L (WNR1.4539) ASTM A 249, N08904, X1NiCrMoCu25-20-5 he kila kila austenitic kiʻekiʻe. Ke hoʻohālikelike ʻia me 316L, SS904L he haʻahaʻa carbon (C) maʻiʻo, kahi kiʻekiʻe o ka chromium (Cr) maʻiʻo, a ma kahi o ka pālua o ka nickel (Ni) a me ka molybdenum (Mo) maʻiʻo o 316L, e hāʻawi ana i kahi mahana kiʻekiʻe ...
904L (N08904,, 14539) super austenitic kuhiliʻole kila he 19.0-21.0% chromium, 24.0-26.0% nikela, a me 4.5% molybdenum. ʻO 904L super austenitic stainless steel he kalapona haʻahaʻa, nickel kiʻekiʻe, molybdenum austenitic stainless acid-resistant steel, he mea waiwai ia i hoʻokomo ʻia mai ka hui Farani H·S. Loaʻa iā ia ka hiki ke hoʻololi-passivation hoʻololi maikaʻi, ke kūpaʻa corrosion maikaʻi, ke kūpaʻa corrosion maikaʻi i nā ʻakika non-oxidizing e like me ka sulfuric acid, acetic acid, formic acid, phosphoric acid, maikaʻi pitting resistance i neutral chloride ion media, a maikaʻi crevice corrosion a me ke kaumaha corrosion kū'ē. He kūpono ia no nā ʻano ʻokoʻa like ʻole o ka sulfuric acid ma lalo o 70 ° C, a he kūpaʻa maikaʻi ka corrosion i ka acetic acid o kekahi ʻano a me kekahi mahana ma lalo o ke kaomi maʻamau, a hui pū ʻia ka waikawa formic a me ka waikawa acetic.
ʻO AISI 904L kila kila he kila austenitic kiʻekiʻe me ka haʻahaʻa haʻahaʻa. ʻO ka hui pū ʻana o ka chromium kiʻekiʻe, nickel, molybdenum a me ke keleawe e hāʻawi ai i ke kila maikaʻi ʻaʻahu kūʻokoʻa. ʻO ka hoʻohui ʻana o ke keleawe he ikaika ia i ka ʻakika, hiki ke pale aku i nā ʻano mea ʻokoʻa a me nā ʻakika inorganic, ʻoi aku ka nui o ka chloride crevice corrosion a me ke koʻikoʻi koʻikoʻi ʻino, ʻaʻole maʻalahi ka loaʻa ʻana o nā wahi ʻino a me nā māwae, a he ikaika ke kū kūʻē ʻana. Loaʻa iā AISI 904L ke kūpaʻa corrosion maikaʻi i ka dilute sulfuric acid. ʻO ke kila he kila kūpono no ka dilute sulfuric acid ikaika corrosive medium. He kūpaʻa nō hoʻi ia i ka wai kai, loaʻa ka machinability maikaʻi a me ka weldability, a hoʻohana nui ʻia i ke kūkulu ʻana, kemika, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe.
ʻO AISI 904L ke kila kila i hoʻohana mau ʻia i nā reactors i ka ʻaila a me nā lako petrochemical; ʻO ka mālama ʻana i ka ʻakika sulfuric a me nā mea halihali, e like me nā mea hoʻololi wela; nā lako hana hoʻoheheʻe kinoea i loko o nā mea kanu mana, e like me nā hale kiaʻi, flues, shutters, nā ʻāpana kūloko, sprayers, fans, etc. nā lako hoʻomaʻemaʻe kai, e like me nā mea hoʻololi wela o ke kai; nā lako hana pepa, sulfuric acid, nitric acid mea hana; nā mea hana kemika, nā ipu kaomi, nā meaʻai e like me ka hana waika a me nā ʻoihana lāʻau.
