Insimbi Engagqwali - Izakhiwo Nezicelo Zamabanga 310/310s Insimbi Engagqwali
Lawa mabanga aqukethe u-25% we-chromium no-20% we-nickel, okuwenza amelane kakhulu ne-oxidation nokugqwala.I-Grade 310S inguqulo yekhabhoni ephansi, ethambekele kancane ekugxilweni nasekuqwashiseni enkonzweni.I-chromium ephezulu kanye nokuqukethwe kwe-nickel emaphakathi kwenza lezi zinsimbi zikwazi ukusetshenziswa ekunciphiseni i-sulphur atmospheres equkethe i-H2S.Asetshenziswa kakhulu ezindaweni eziphansi ze-carburising, njengoba kutholakala ezindaweni ze-petrochemical.Ukuze uthole izimo ezinzima kakhulu ze-carburising, ezinye izingxube ezimelana nokushisa kufanele zikhethwe.Ibanga 310 alituswa ukuthi licime uketshezi njalo njengoba lihlushwa ukushaqeka okushisayo.Ibanga livame ukusetshenziselwa izinhlelo zokusebenza ze-cryogenic, ngenxa yokuqina kwayo kanye nokufinyeleleka okuphansi kazibuthe.
Ngokufana nezinye izinsimbi ezingenasici ze-austenitic, lawa mabanga awakwazi ukwenziwa lukhuni ukwelashwa okushisa.Zingenziwa lukhuni ngomsebenzi obandayo, kodwa lokhu akuvamile ukwenziwa.

Ukwenziwa kweBanga 310/310S Lensimbi Engagqwali
I-Fabrication Amabanga 310/310S akhiwe ezingeni lokushisa elingu-975 – 1175°C.Umsebenzi osindayo wenziwa wehle uze ufike ku-1050°I-Cand finish light isetshenziswa ngaphansi kobubanzi.Ngemuva kokubumba i-annealing kunconywa ukukhulula konke ukucindezelwa kwenqubo yokubumba.Ama-alloys angabanda kalula akhiwe ngezindlela ezijwayelekile kanye nemishini.
Imishini yeBanga 310/310S yensimbi engagqwali
I-Machinability Amabanga 310/310SS ayafana ngokukwazi ukuthayipha u-304. Ukuqina komsebenzi kungaba yinkinga futhi kuvamile ukususa ungqimba oluqinile lomsebenzi ngokusebenzisa isivinini esinesivinini kanye nokusikeka okunzima, ngamathuluzi abukhali kanye nokugcotshwa okuhle.Kusetshenziswa imishini enamandla namathuluzi asindayo, aqinile.
Welding of Grade 310/310S Stainless Steel
Ukushisela Amabanga 310/310S ashiselwe ngama-electrode afanayo nezinsimbi zokugcwalisa.Ama-alloys ashiselwa kalula yi-SMAW (manual), GMAW (MIG), GTAW (TIG) kanye ne-SAW.Ama-Electrode kuya ku-AWS A5.4 E310-XX kanye ne-A 5.22 E310T-X, kanye ne-filler metal AWS A5.9 ER310 asetshenziswa.I-Argon ivikela igesi.Ukushisa ngaphambi nangemva kokushisa akudingekile, kodwa ngesevisi yokugqwala oketshezini olugcwele lwesisombululo se-weld ukwelashwa kubalulekile.Ukucofa kanye nokwedlula indawo okungaphezulu ukuze kukhishwe ama-oxide okushisa aphezulu kubalulekile ukubuyisela ukumelana nokugqwala okugcwele kwamanzi ngemva kokushisela.Lokhu kwelashwa akudingekile ngenkonzo yokushisa ephezulu, kodwa i-welding slag kufanele isuswe ngokuphelele.
Ukwelashwa Kokushisa KweBanga 310/310S Insimbi Engagqwali
Uhlobo Lokwelapha Ukushisa 310/310S luyisixazululo esivalwa ngokushisisa izinga lokushisa elingu-1040 -1065°C, libambe izinga lokushisa lize licwiliswe kahle, bese amanzi ecisha.
Ukumelana Nokushisa KweBanga 310/310S Insimbi Engagqwali
Amabanga 310/310S anokumelana okuhle ne-oxidation kusevisi yesikhashana emoyeni kuze kufike ku-1035°Cand 1050°Cin isevisi eqhubekayo.Amabanga amelana ne-oxidation, i-sulphidation kanye ne-carburisation.
Amafomu Atholakalayo Ebanga 310/310S Insimbi Engagqwali
I-Austral Wright Metals ingahlinzeka ngalawa mabanga njengepuleti, ishidi kanye ne-strip, ibha nenduku, ishubhu nepayipi elingenamthungo, ishubhu elishiselwe nepayipi, ama-forging ne-forging billet, amashubhu namapayipi okuhlanganisa, intambo.I-Corrosion Resistance Grade 310/310S ngokuvamile ayisetshenziselwa isevisi yoketshezi olubolayo, nakuba i-chromium ephezulu ne-nickel okuqukethwe kunikeza ukumelana nokugqwala okuphakeme kune-grade 304. Ingxubevange ayinayo i-molybdenum, ngakho ukumelana nomgodi kubi kakhulu.IBanga 310/310S lizokwaziswa ukugqwala kwe-intergranular ngemva kwesevisi emazingeni okushisa aphakathi kwama-550 - 800°C.I-Chloride stress corrosion cracking ingase yenzeke oketshezini olubolayo oluqukethe ama-chloride emazingeni okushisa angaphezu kuka-100°C.
