1. Izinto ezibonakalayo
Izakhiwo ezingokomzimba ze-202 kanye nezinsimbi zochungechunge ezingama-300 ezihambisanayo esimweni sokwelashwa kwesixazululo, izakhiwo ezibonakalayo zochungechunge lwama-200 kanye nochungechunge lwe-300 zicishe zifane. Kodwa-ke, ushintsho ekungeneni ngemuva kokusebenza okubandayo luhlukile. Ngenxa yezinga elihlukile le-mutagenic martensite ngesikhathi sokusebenza okubandayo, ukwanda kokungena kuncane kunochungechunge lwe-200 kanye nochungechunge lwe-300.
2. Ukuziphatha kwemishini
I-201 ne-202 zihlukile kwezinye izinto zochungechunge ezingama-200. Njengo-301 no-302, zonke zingama-austenitic stainless steels anezakhiwo ezinkulu eziqinisa umsebenzi. Lezi zinsimbi zinamajika aqinisa umsebenzi. 201 kanye no-301 kanye no-202 kanye no-302 banezici ezifanayo zokuqina. 201,301 Ukuqina komsebenzi kukhulu. Inani le-martensite elikhiqizwayo lihlukile ebangeni ngalinye. I-202,304 martensite ikhiqiza okuncane kakhulu, futhi ukusebenza kanzima kuncike kakhulu ekukhubazekeni. Ezinsimbi ezingaphansi kuka-204 no-204L, cishe konke ukuqina komsebenzi kuncike ekuhlanekeni. Izakhiwo zemishini kanye nokuqina kwezinto zochungechunge lwe-CrMnN kuboniswa kuThebula 5. Ukuqina kwalezi zinsimbi esimweni sokwelashwa kwesisombululo cishe ku-HV250, futhi amandla ngemva kokuqiniswa okubandayo aphakeme, futhi i-Hv ingafinyelela ku-500, kodwa ukuvuthwa. isengaphansi kuka-1.005 kulesi sifundazwe.
Uhlelo lokusebenza:
Ipayipi lensimbi engagqwali engu-202 ingeyochungechunge lwama-200. Ukuthuthukiswa kwasekuqaleni kuthathe indawo yensimbi engenasici engu-18-8 chromium-nickel austenitic nge-manganese ne-nitrogen esikhundleni se-nickel. I-18-8 uhlobo lwe-Cr-Ni insimbi engagqwali 301, 302, 304 (kuhlanganise ne-321) ibalwa ngaphezu kwe-50% yomkhiqizo ophelele wensimbi engagqwali. Lawa mabanga ensimbi anezakhiwo ezinhle kakhulu ezibanzi ezifana nokumelana nokugqwala, izakhiwo zemishini, izakhiwo zokushisa eziphakeme neziphansi, izakhiwo zenqubo, nezakhiwo zokuhlobisa. Zisetshenziswa kabanzi emikhakheni ehlukahlukene kusukela komphakathi kuya kwezempi kanye nomhlobiso wezakhiwo zomphakathi. Imishini yasendlini, izinto zasekhishini kanye nezitsha, ezokuthutha, ukuvikelwa kwemvelo, ukwakhiwa kukamasipala; izindiza zezempi, indiza, imboni yenuzi, imikhumbi; izimboni zezimboni zamakhemikhali, umanyolo, i-petroleum, izindwangu, ukuphrinta, iphepha, amandla. Ithebula 1 libala uchungechunge lwe-AISI200 lwezinsimbi ezingenasici ze-manganese eziqukethe i-austenitic. Ngakho izifundo zakuqala ezingu-201, 202, 204, 205, 206 zihambisana nochungechunge lwe-Cr-Ni 301, 302, 304, 305, 316. Okulandelayo, 211 yathuthukiswa ukuze isebenzise amamaki ensimbi ane-carbon nitrogen, Mn, kanye ne-Cu-added steel ukusebenza okubandayo. I-201L, 201LN, njll. iyintuthuko ye-201 ukuxazulula inkinga yokugqwala kwengcindezi ye-intergranular.
I-high-nitrogen CrMnN austenitic steel stainless steel inamandla amakhulu, ukuqina, ukumelana nokugqoka okuphezulu, okungezona uzibuthe, ukumelana nokugqwala nezinye izici, futhi inezidingo eziningi embonini. Ngokuzayo, kuzoba nentuthuko enkulu kulezi zindawo ezilandelayo:
1. Insimbi ene-nitrogen ephezulu ye-CrMnNiN enamandla amakhulu, ukumelana nokugqwala okuphezulu kanye nokuqina okuhle kwezinga lokushisa eliphansi ingasetshenziselwa izindiza, i-aerospace kanye nemikhumbi enezinduku zokusebenza ezinhle kakhulu, izintambo, ama-forging, amapuleti aphakathi nendawo, namapuleti amancane okwenza iziqukathi, amapayipi, ama-valve, Amakhebuli, njll.
2. Insimbi engagqwali engagugi, imelana nokugqwala, ukuqina okuphezulu kanye ne-nitrogen ephezulu ye-CrMnN austenitic yensimbi engagqwali ingahlinzeka ngemishini engagqwali, engagugi kanye nezinto zokwakha zemishini yezimayini embonini yezimayini.
3. Insimbi engenazibuthe, enamandla amakhulu, imelana nokugqwala, i-nitrogen ephezulu ye-CrMnMoN austenitic steel stainless, engahlinzeka ngamakholomu okubhoboza angenawo uzibuthe wamasimu kawoyela, nezindandatho zonogada ezingenawo uzibuthe zamajeneretha ezitshalo zamandla. 4. Ukumelana nokugqwala okuphezulu, ukumelana nokugqwala kwe-crevice kanye ne-nitrogen ephezulu i-CrNiMnMoN Insimbi engagqwali ye-Austenitic ingahlinzeka ngezinto zokushintshanisa ukushisa kwamanzi olwandle, okokusebenza kokukhipha usawoti emanzini olwandle, kanye namadivayisi okukhipha igesi e-flue emafekthri asogwini.
