I-Chromium, i-molybdenum ne-nitrogen kukhulisa ukumelana nokugqwala okukhonkotha. I-nickel ifaka isakhiwo se-auntenitic.
Ingafakwa kalula futhi icutshungulwe yimikhuba yokuqamba ye-stack shop evamile.
? Ukuqukethwe okuphansi kwekhabhoni ye-alloy 317l kukuvumela ukuthi kufakwe i-weld ngaphandle kokugqwala okuvela ekugxoliseni kwe-chromium carbide ukukwenza kube lula ukusetha isehlakalo se-as-welded.
Alloy 347 Iplate yensimbi engenasici ibonisa ukumelana nokuqina okujwayelekile okuqhathaniswa no-304.
U-IS31254 uvame ukubizwa ngokuthi yi-¡° 6% moly¡ ± ibanga ngenxa yokuqukethwe kwe-molybdenum.
Umndeni weMoly unekhono lokumelana namazinga okushisa aphezulu futhi alondoloze amandla ngaphansi kwezimo eziguqukayo.
Leli banga ledlule inhloso yalo lasekuqaleni futhi lifakwe ezimbonini eziningi ezifakazela ngenxa yezinga eliphakeme le-molybderum inani ezinye izinto eziphathelene nezinsiza ezihlukile njengokuphelelwa yigesi kwe-flue kanye nezindawo zamakhemikhali.
I-Stainless yensimbi ibanga 254 SMO? yinsimbi ephezulu kakhulu yensimbi engenacala.
Kuklanyelwe ukuhlanganiswa kobunzima bokuqina kobunzima bokugqwala kwe-chloride ukuqhekeka kokuqhekeka, kanye nokugqwala okukhohlisayo kanye nokugqwala kwamandla ngamandla okuphindwe kabili kochungechunge lwensimbi engama-300.
I-316 ingadedelwa ukuthi imelane nokuwohloka kwe-weld.
I-316l nayo yensimbi enhle engabi nesiqhingi ekushiseni okuphezulu, ukusetshenziswa okuphezulu kokugqwala, yingakho kudumile kakhulu ukusetshenziswa ekwakhiweni kwezokwakha nasezandleni zasolwandle.
I-904L I-Steressless yensimbi ayifani nanoma iyiphi enye insimbi. Ngenxa yamanani angeziwe angeziwe we-chromium, i-molybdenum, i-nickel ne-zethusi, insimbi engu-904l ifaka ukumelana okuphezulu kokugqwala, ukugqwala kanye nama-acid.
Alloy 347 (uns s34700) nguColumbium waqinisa ipuleti yensimbi engenacala engenacala ngokumelana kahle nokuphikiswa okujwayelekile kanye nokuphikiswa okungcono ezimweni eziqinile ze-oxidizing eziqinile kune-321 (uns s32100).
Ukungezwa kwethusi kuleli banga kukunikeza ukumelana okungcono kokugqwala kune-Chromium-Nickel Steel engenacala, ikakhulukazi ngokumelene ne-Sulfuric, phosphoric kanye ne-acetic acids. Kodwa-ke, ukusetshenziswa kwe-hydrochloric acid kukhawulelwe.
Inokumelana kahle nokugqwala kokuhlangana kwezingalo ngemuva kokuchayeka kumazinga okushisa asezingeni le-Chromium Carbide Preiptitupation uhla lwe-800 ¨c 1500¡Ãf (427 ¨c 816¡Ãc (427 ¨c 816¡Ãc (427 ¨c 81¡¡Ãc).?
Insimbi engenasici 904L \ 15539 impahla ingasetshenziswa ukwenza ishidi elishisayo nelibandayo, imikhiqizo eqediwe, imigoqo ye-rolled, kanye namapayipi athuliwe kanye namaphrofayili ezicelo zokucindezela.
I-alloy inokumelana ne-oxidation enhle kanye namandla aqhakazayo ku-1500¡Ãf (816¡Ãc). Iphinde futhi ibe nobunzima bokushisa okuphansi okuphansi.
I-Alloy 904L ihluphuke ezinye izinsimbi ze-autenitic ezingenasici ngenxa yezinga eliphakeme lokwabiwa kwe-nickel ne-molybdenum.
Alloy 347h (us s3409) ipuleti yensimbi engagqwali yi-carbon ephakeme (0.04 ¨c 0.10) inguqulo ye-alloy.
Okuqukethwe okuphezulu kwe-chromium kukhuthaza futhi kugcinwe ifilimu nje evikela impahla ezindaweni eziningi ezilonakalisayo.
Lapho ukhetha ama-sterainless steres okufanele ubekezelele izindawo ezilonakalisayo, ama-autenitic angenazinsimbi ajwayele ukusetshenziswa.
Amanani aphezulu e-nickel ne-chromium e-autenitutic steress acrenless anikeza izakhiwo ezinhle kakhulu zemishini, kanye nokuphikiswa okuhle kakhulu kokugqwala.
Insimbi yebanga le-304 ngokuvamile libhekwa njengensimbi evame kakhulu ye-auntenitic.
Amabanga amabili ajwayelekile ensimbi ajwayelekile angama-304 no-316. Umehluko omkhulu ukufakwa kwe-molybdenum, i-alloy ethuthukisa kakhulu ukumelana nokukhulisa, ikakhulukazi ezindaweni ezinosawoti noma nge-chloride.
I-304 Insimbi Engagqwali yindlela evame kakhulu yensimbi engagqwali emhlabeni ngenxa yokumelana nokuqina kwayo okuhle kakhulu nokubaluleka. Ine-16% kuya ku-24% i-chromium futhi ifike ku-35% nickel, kanye namanani amancane e-carbon naku-manganese.
I-304 insimbi engagqwali inobuthakathaka obunye: Itholakala ekugculweni okuvela kwizixazululo ze-chloride noma ezindaweni zesawoti ezifana nogu.
Insimbi engu-316 inensimbi engagqwali inekhabhoni eningi kuyo kune-316L. Lokhu kulula ukukhumbula, njengoba i-L imile "ephansi."
I-316L ifana kakhulu ne-316 cishe ngazo zonke izindlela.?
I-316l, nokho, ukukhetha okungcono kwephrojekthi edinga ukufudumala okuningi ngoba i-316 itholakala kalula ekuwohlokeni kwamandla ku-316L (ukugqwala ngaphakathi kweWeld).
Zisetshenziselwa insiza yokushisa ephezulu, lapho kudingeka khona i-oxidation kanye ne-carburburation. Ngezakhiwo ezinhle kakhulu zokucindezela kwengcindezi, noma insiza yomkhumbi yengcindezi engenhla kwe-815¡Ãc, incoloy 800h noma incoloy 800ht kufanele isetshenziswe.
