ʻO ke kila kila kila AISI 904L a i ʻole AISI 904L (WNR1.4539) ASTM A 249, N08904, X1NiCrMoCu25-20-5 he kila kila austenitic kiʻekiʻe. Ke hoʻohālikelike ʻia me 316L, ʻoi aku ka haʻahaʻa o ke kalapona (C) o SS904L, ʻoi aku ka kiʻekiʻe o ka chromium (Cr), a ʻoi aku ka pālua o ka nickel (Ni) a me ka molybdenum (Mo) o 316L, e hāʻawi ana i kahi mahana kiʻekiʻe...
ʻO ke kila kila austenitic super 904L (N08904,, 14539) he 19.0-21.0% chromium, 24.0-26.0% nickel, a me 4.5% molybdenum. ʻO ke kila kila austenitic super 904L he kila haʻahaʻa kalapona, nickel kiʻekiʻe, molybdenum austenitic stainless acid-resistant, he mea ponoʻī ia i hoʻolauna ʻia mai ka hui Farani H·S. Loaʻa iā ia ka hiki ke hoʻololi i ka hoʻāla-passivation maikaʻi, ke kūpaʻa maikaʻi loa i ka pala, ke kūpaʻa maikaʻi i ka pala i nā waikawa non-oxidizing e like me ka sulfuric acid, acetic acid, formic acid, phosphoric acid, kūpaʻa pitting maikaʻi i ka media ion chloride neutral, a me ka pale maikaʻi i ka pala crevice a me ke kūpaʻa i ka pala. He kūpono ia no nā ʻano like ʻole o ka waikawa sulfuric ma lalo o 70°C, a he kūpaʻa maikaʻi i ka pala i ka waikawa acetic o kekahi ʻano a me kekahi mahana ma lalo o ke kaomi maʻamau, a me ka waikawa hui o ka waikawa formic a me ka waikawa acetic.
ʻO ke kila kila kila AISI 904L kahi kila kila austenitic kiʻekiʻe-alloy me ka haʻahaʻa loa o ke kalapona. ʻO ka hui pū ʻana o ka chromium kiʻekiʻe, nickel, molybdenum a me ke keleawe e hāʻawi i ke kila i ke kūpaʻa maikaʻi i ka pala. ʻO ka hoʻohui ʻana o ke keleawe e loaʻa iā ia ke kūpaʻa waikawa ikaika, hiki ke kūʻē i nā ʻano waikawa organik a me nā inorganic, ʻoi aku ka pala o ka chloride crevice a me ka haki ʻana o ka pala, ʻaʻole maʻalahi ke loaʻa nā kiko pala a me nā māwae, a he kūpaʻa pitting ikaika. Loaʻa iā AISI 904L ke kūpaʻa maikaʻi i ka pala i ka waikawa sulfuric dilute. ʻO ke kila he kila kūpono no ka waikawa sulfuric dilute ikaika corrosive medium. He kūpaʻa hoʻi ia i ka wai kai, he maikaʻi ka mīkini a me ka weldability, a hoʻohana nui ʻia i ke kūkulu ʻana, kemika, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe.
Hoʻohana pinepine ʻia ke kila kila AISI 904L i nā reactors i nā lako petroleum a me petrochemical; nā lako mālama a me ka halihali waikawa sulfuric, e like me nā mea hoʻololi wela; nā lako desulfurization kinoea flue i nā mea kanu mana, e like me nā hale kiaʻi, nā flue, nā pani, nā ʻāpana kūloko, nā mea pīpī, nā mea pā, a pēlā aku i nā ʻōnaehana mālama waikawa organik; nā lako mālama wai kai, e like me nā mea hoʻololi wela wai kai; nā lako ʻoihana pepa, waikawa sulfuric, nā lako waikawa nitric; nā lako kemika, nā kīʻaha kaomi, nā lako meaʻai e like me ka hana waikawa a me nā ʻoihana lāʻau lapaʻau.

Nā kikoʻī hana e Womic Steel: Loaʻa nā paipu kila kila 904L i nā nui hana like ʻole ma ka laina hana Womic Steel, me nā paipu humuhumu ʻole a me nā paipu i hoʻopaʻa ʻia. ʻO ke anawaena o waho o nā paipu humuhumu ʻole maʻamau mai 3 a 720 mm (φ1 a 1200 mm), me ka mānoanoa o ka paia o 0.4 a 14 mm; ʻo ke anawaena o waho o nā paipu i hoʻopaʻa ʻia maʻamau mai 6 a 508 mm, me ka mānoanoa o ka paia o 0.3 a 15.0 mm.
