904 ipu uamea stainlesso se ituaiga austenitic uʻamea uʻamea ma maualalo tele carbon anotusi ma alloying maualuga fuafuaina mo siosiomaga ma tulaga corrosion faigata. E sili atu le tete'e o le corrosion nai lo le 316L ma le 317L, a'o amanaia uma le tau ma le faatinoga. Lelei tau tupe. Ona o le faʻaopoopoga o le 1.5% kopa, e sili ona lelei le faʻafefeteina e tetee atu ai i le faʻaitiitia o vailaʻau e pei ole sulfuric acid ma le phosphoric acid. O lo'o i ai fo'i le lelei tele o le tete'e atu i le pala, pitting ma clevice corrosion e mafua mai i ions lavelave, ma e lelei le tete'e atu i intergranular corrosion. I totonu o le sulfuric acid mama i le faʻatonuga o le 0-98%, o le vevela o le auaunaga o le 904L ipu uamea e mafai ona maualuga e pei o le 40 tikeri Fahrenheit.
I totonu o le acid mama i le faʻatonuga o le 0-85%, o lona teteʻe faʻafefe e lelei tele. I totonu o fale gaosi oloa phosphoric acid e gaosia e ala susu, o mea eleelea e i ai se aafiaga malosi i le tetee atu. I totonu o ituaiga uma o acids, 904L super austenitic stainless steel e sili atu le corrosion teteʻe nai lo masani stainless steel. I le malosi oxidizing nitric acid, 904L u'amea u'amea e maualalo le pala nai lo uʻamea sili ona alloyed e leai se siliva. I le hydrochloric acid, o le faʻaaogaina o904L ipu uamea uameae faʻatapulaʻa i faʻasalalauga maualalo o le 1-2%.
