Izinto eziphathekayo
1.4112 (S46990, S44003, sus440b, X90CrMoV18)
ukwakheka kweekhemikhali
C: 0.85～0.95%; Si: ≤1.0%; UMn: ≤1.0%; P: ≤0.04%; S: ≤0.015%; Cr: 17～19%; Mo: 0.9～1.3%; I-V: 0.07～0.12 %; Fe: balance
Iimpawu zezinto eziphathekayo
Ubuninzi: 7.7g/cm³; amandla okuqina: 590MPa; amandla emveliso: 245MPa; ubude: 15%; ubunzima HBW: 269; ukucima kunye nokuthoba ubunzima: 55HRC.
Indlela yokuziphatha koomatshini
I-1.4112 yintsimbi ye-carbon martensitic ephezulu. Iimpawu zayo zemishini zibandakanya amandla, ubunzima, ubunzima, njl. Ngenxa yekhabhoni ephezulu kunye nomxholo we-chromium, olu hlobo lwensimbi lunamandla amakhulu kunye nobunzima kwaye lunokumelana noxinzelelo olukhulu kunye nokugqoka. Ngelo xesha, ngenxa yokuqina kwayo okulungileyo, olu hlobo lwensimbi alulula ukukhupha kwaye lunokusetyenziswa kwiindawo eziyinkimbinkimbi. Ukumelana nokubola ukusuka kwiatmosfera ethambileyo, umphunga wamanzi amatsha, i-ammonia, iimveliso ezininzi zepetroleum kunye nezinto eziphilayo, kunye neendawo ezahlukeneyo ezineasidi ebuthathaka. Ubushushu be-annealing buphantsi kakhulu, kwaye ukuqina emva kokucinywa kuphezulu. Ubunzima buhlala bufikelela kwi-HRC56-58. Inokumelana ne-corrosion elungileyo (imagnetic) kunye nokuqina olomeleleyo.
Iindawo zesicelo
Ngenxa yokuba i-1.4112 insimbi engenasici ine-corrosion resistance resistance and mechanical properties, isetyenziswa ngokubanzi kwi-petroleum, imboni yeekhemikhali, ubunjineli baselwandle, iimoto, ukutya kunye nezinye iindawo. Kwimizi-mveliso yepetroleum kunye neekhemikhali, ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, isetyenziselwa ukwenza ii-reactors, imibhobho kunye nezinye izixhobo. Kwinkalo yobunjineli baselwandle, isetyenziselwa ukwenza iinxalenye eziphambili zeenqanawa kunye namaqonga aselwandle. Kwintsimi yeemoto, isetyenziselwa ukwenza izinto ezifana neenkqubo zokukhupha kunye nezibophelelo. Kwintsimi yokutya, isetyenziselwa ukwenza izixhobo zasekhitshini kunye nezixhobo zokulungisa ukutya ngenxa yeempawu zayo ezilungileyo zococeko.
Ukusebenza kwenkqubo
Iipropathi zenkqubo ye-1.4112 yensimbi engenasici ikakhulu ibandakanya i-welding, unyango lobushushu kunye nepropathi yokucubungula. Olu hlobo lwentsimbi lunokusebenza kakuhle kwe-welding kwaye lunokudityaniswa kusetyenziswa iindlela ezahlukeneyo ze-welding. Ukunyangwa kokushisa kunokuphucula iimpawu zayo zemishini kunye nokuchasana nokubola, kodwa kufuneka kuthathelwe ingqalelo ukuthintela ukuqhekeka okanye ukuguqulwa okubangelwa ukushisa okanye ukugqithisa. Inokusebenza kakuhle kwaye ingasetyenziselwa ukujika, ukugaya, ukugrumba, ukucofa kunye neminye imisebenzi yokucubungula. Ukungalungi kwayo kukuba incangathi kwaye iyatshisa ngokukhawuleza, kodwa kulula ukuyisa isanti kunayo nayiphi na intsimbi yekhabhoni kwaye kulula ukuyisika ngesarha yesandla.
