SS904L AISI 904L Steel-Stainless (UNS N08904)

Sharaxaad Gaaban:

UNS NO8904, oo loo yaqaan 904L, waa kaarboon hoose oo austenitic ahama bir ah oo si weyn loogu isticmaalo codsiyada halka sifooyinka daxalka ee AISI 316L iyo AISI 317L aysan ku filneyn. 904L waxay bixisaa iska caabin dildilaaca daxalka chloride wanagsan, iska caabinta daxalka, iyo iska caabinta daxalka guud ee ka sarreeya 316L iyo 317L molybdenum birta aan la wadin.

Hordhac Product

AISI 904L ahama bir ah (UNS N08904) waa bir austenitic austenitic ah oo sare. Marka la barbar dhigo 316L, SS904L waxa ku jira kaarboon (C) hoose, chromium (Cr) ka kooban, iyo qiyaastii laba jeer nikkel (Ni) iyo molybdenum (Mo) ka kooban316L, taas oo ka dhigaysa in ay leedahay iska caabin oksaydh heer sare ah oo heerkul sare ah, iska caabin godad leh, iyo iska caabin yaraynta aashitada (tusaale, sulfuric acid). Nitrojiin (N) waxay yarayn kartaa heerka roobabka chromium carbide, taas oo hoos u dhigaysa dareenka dareenka, waxay sidoo kale wanaajisaa caabbinta godadka iyo daxalka dillaaca ee ay keento chlorides. Gaar ahaan ku darida naxaasta (Cu) waxay ka dhigtaa mid waxtar u leh dhammaan uruurinta sulfuric acid.

Alloy 904L wuxuu u shaqeeyaa si ka wanaagsan biraha kale ee austenitic ahama sababtoo ah alloying sare ee nikkel iyo molybdenum. Darajaddu waa mid aan magnet-ka ahayn dhammaan xaaladaha waxayna leedahay qaabayn heersare ah iyo alxan. Qaab dhismeedka austenitic ayaa sidoo kale siinaya darajadan adkeysi aad u fiican, xitaa hoos udhaca heerkulka cryogenic Maaddooyinka chromium sare waxay kor u qaadaan oo ilaalisaa filim aan qarsoodi ahayn kaas oo ka ilaaliya walxaha meelo badan oo daxalka ah. Ma jirto khatar ah daxalka intercrystalline ee qaboojinta ama alxanka sababtoo ah waxa ku jira kaarboon yar. Heerkulkeeda adeeg ee ugu badan waa 450°C. Darajadani waxay si gaar ah faa'iido ugu leedahay xakamaynta iyo codsiyada tubbada qalabaynta halka 316 iyo 317L aanay ku haboonayn.

Alloy 904L ayaa markii hore loo sameeyay si ay ugu adkaysato bay'ada ay ku jirto sulfuric acid. Waxa kale oo ay siisaa iska caabin wanaagsan oo aysiidh kale oo inorganic ah sida phosphoric acid kulul iyo sidoo kale inta badan asiidhyada organic.

Alloy 904L si sahal ah ayaa loo alxan karaa oo looga baaraandegay dhaqamada wax-soo-saarka dukaanka caadiga ah.

904L ahama (SS904L) waxaa loo isticmaalaa in batroolka, kiimikaad, bacriminta, munaaradaha horumarinta badda, taangiyada, tuubooyinka iyo tuubooyinka iyo kulaylka sarrifka. Rolex iyo kuwa kale ee soo saara saacadaha ayaa sidoo kale u isticmaala samaynta saacadaha
