SS904L AISI 904L Bir aan miridh lahayn (UNS N08904)
Hordhac Badeecada
Bir aan miridh lahayn oo AISI 904L ah (UNS N08904) waa bir aan miridh lahayn oo austenitic ah oo aad u tayo badan. Marka la barbardhigo 316L, SS904L waxay leedahay kaarboon (C) oo hooseeya, chromium (Cr) oo sarreeya, iyo qiyaastii labanlaab tirada nikkel (Ni) iyo molybdenum (Mo) ee316L, taas oo ka dhigaysa inay leedahay iska caabin oksaydh heerkul sare oo sarreeya, iska caabin god, iyo iska caabin yareysa aashitada (tusaale ahaan, aashitada sulfuric). Nitrogen (N) wuxuu yareyn karaa heerka roobabka chromium carbide, taasoo yareyneysa xasaasiyadda dareenka, waxay sidoo kale hagaajineysaa iska caabinta godadka iyo daxalka godadka ee ay keento chlorides. Gaar ahaan ku darista naxaasta (Cu) waxay ka dhigaysaa mid waxtar u leh dhammaan uruurinta aashitada sulfuric.
Daawaha 904L wuxuu ka shaqeeyaa si ka wanaagsan biraha kale ee aan lahayn austenitic sababtoo ah isku-darka sare ee nikkel iyo molybdenum. Darajadu waa mid aan birlab ahayn dhammaan xaaladaha waxayna leedahay qaab-dhismeed aad u fiican iyo alxan. Qaab-dhismeedka austenitic wuxuu sidoo kale siinayaa darajadan adkeysi aad u fiican, xitaa heerkulka cryogenic. Waxyaabaha sare ee chromium waxay kor u qaadaan oo ilaaliyaan filim aan firfircooneyn oo ilaaliya walxaha jawi badan oo daxal leh. Ma jirto khatar ah in daxalku uu dhex maro qaboojinta ama alxanka sababtoo ah kaarboon yar. Heerkulka adeegga ugu badan waa 450°C. Darajadani waxay si gaar ah waxtar ugu leedahay codsiyada xakamaynta iyo qalabka tuubooyinka halkaas oo 316 iyo 317L aysan ku habboonayn.
Daawaha 904L waxaa asal ahaan loo sameeyay si uu u adkeysto deegaan ay ku jiraan aashitada sulfuric-ga ee khafiifka ah. Waxa kale oo uu bixiyaa iska caabin wanaagsan oo ka dhan ah aashitada kale ee aan organic ahayn sida aashitada phosphoric-ga kulul iyo sidoo kale aashitada organic-ga badankood.
Daawaha 904L si fudud ayaa loo tolaa oo loo farsameeyaa iyadoo la adeegsanayo dhaqamada wax soo saarka dukaanka caadiga ah.
Bir aan miridh lahayn oo 904L ah (SS904L) ayaa loo isticmaalaa batroolka, kiimikada, bacriminta, munaaradaha horumarinta badda, haamaha, tuubooyinka iyo tuubooyinka iyo beddelayaasha kulaylka. Rolex iyo soosaarayaasha kale ee saacadaha ayaa sidoo kale u isticmaala inay sameeyaan saacadaha.
