Marka la barbar dhigo 316L, SS904L waxay leedahay kaarboon hoose (C), ka kooban chromium (Cr) sare, iyo qiyaastii laba jeer nikkel (Ni) iyo molybdenum (Mo) ka kooban 316L, taasoo siinaysa heerkul sare...
904L (N08904,, 14539) super austenitic birta aan lahayn waxaa ku jira 19.0-21.0% chromium, 24.0-26.0% nikkel, iyo 4.5% molybdenum. 904L super austenitic ahama birta waa kaarboon hoose, nikkel sare, molybdenum austenitic ahama aashitada u adkaysta, kaas oo ah walxo iska leh oo laga keenay shirkadda Faransiiska HS. Waxay leedahay karti-is-beddel wanaagsan oo firfircoon, iska caabin wanaagsan oo daxalka ah, iska caabbinta daxalka wanaagsan ee asiidhyada aan oksaydhka ahayn sida sulfuric acid, acetic acid, formic acid, phosphoric acid, iska caabin wanaagsan oo dhexda ah ee warbaahinta chloride ion dhexdhexaad ah, iyo iska caabbinta daxalka wanaagsan. Waxay ku habboon tahay uruurinta kala duwan ee sulfuric acid ee ka hooseeya 70 ° C, waxayna leedahay caabbinta daxalka wanaagsan ee acetic acid ee fiirsashada kasta iyo heerkul kasta oo cadaadiska caadiga ah, iyo aashitada isku dhafan ee formic acid iyo acetic acid.
AISI 904L ahama birta waa bir daawaha austenitic austenitic ah oo heer sare ah oo leh kaarboon aad u hooseeya. Isku darka chromium sare, nikkel, molybdenum iyo naxaas ayaa siinaya birta iska caabin daxalka wanaagsan. Ku darida naxaasta waxay ka dhigtaa iska caabin adag oo aysiidh ah, waxay iska caabin kartaa asiidhyada kala duwan ee organic iyo inorganic, gaar ahaan chloride crevice corrosion iyo stress daxalka, ma fududa in la yeesho dhibco iyo dildilaaca, waxayna leedahay iska caabin adag oo godad ah. AISI 904L waxay leedahay iska caabin daxalka wanaagsan ee sulfuric acid. Alloysku waa bir ku habboon aashitada sulfuric ee milo dhexdhexaad ah oo xoog badan. Waxa kale oo ay adkaysi u leedahay biyaha badda, waxa ay leedahay farsamayn fiican oo alxan leh, waxana aad loogu isticmaalaa dhismaha, kiimikada, caafimaadka iyo warshadaha kale.
AISI 904L birta aan lahayn waxaa caadi ahaan loo isticmaalaa reactors ee batroolka iyo qalabka batroolka; kaydinta aashitada sulfuric iyo qalabka gaadiidka, sida kuwa kulaylka beddela; Qalab desulfurization gaaska qiiqa ee dhirta tamarta, sida munaaradaha, qiiqa, xidhitaannada, qaybaha gudaha, buufiyeyaasha, marawaxadaha, iwm ee hababka daaweynta acid organic; Qalabka lagu daweeyo biyaha badda, sida kuleyliyaha biyaha badda; qalabka warshadaha waraaqaha, sulfuric acid, qalabka nitric acid; qalabka kiimikada, weelasha cadaadiska, qalabka cuntada sida samaynta aashitada iyo warshadaha dawooyinka.
