1. sifooyinka jirka
Guryaha jireed ee 202 iyo 300 ee birta ah ee u dhiganta ee ku jira xaaladda daaweynta xalka, sifooyinka jireed ee 200 ee taxanaha iyo 300 ee taxanaha ayaa ku dhow isku mid. Si kastaba ha noqotee, isbeddelka ku-meel-gaarnimada ka dib shaqada qabowgu waa ka duwan tahay. Sababo la xiriira heerka kala duwan ee martensite mutagenic inta lagu guda jiro shaqada qabow, kororka permeability waa ka yar yahay 200 taxane iyo 300 taxane.
2. Dabeecadda makaanikada
201 iyo 202 way ka duwan yihiin 200 oo qalab oo taxane ah. Sida 301 iyo 302, dhamaantood waa bir bir ah oo aan lahayn austenitic oo leh astaamo adag oo shaqo. Birahani waxay leeyihiin qaloocyada adag ee shaqada. 201 iyo 301 iyo 202 iyo 302 waxay leeyihiin sifooyin adag oo isku mid ah. 201,301 Adkeynaanshaha shaqada ayaa ka weyn. Qadarka martensite ee la soo saaray waa ka duwan yahay fasal kasta. 202,304 martensite waxay soo saartaa wax aad u yar, iyo adkaanta shaqada inta badan waxay ku xiran tahay qallooca. Biraha ka hooseeya 204 iyo 204L, ku dhawaad dhammaan adkeynta shaqada waxay kuxirantahay qallooc. Guryaha farsamada iyo ka-hortagga walxaha taxanaha ee CrMnN ayaa lagu muujiyey Shaxda 5. Qalafsanaanta birtan ee ku jirta xaaladda daaweynta xalku waxay ku saabsan tahay HV250, iyo xoogga ka dib qallafsanaanta qabowga ayaa ka sarreeya, Hv-gu wuxuu gaari karaa 500, laakiin ka-hortagga ayaa weli ka hooseeya 1.005 gobolkan.
Codsiga:
202 tuubooyin bir ah oo aan lahayn ayaa iska leh 200 oo taxane ah. Horumarkii hore wuxuu bedelay 18-8 chromium-nickel austenitic birta aan lahayn manganese iyo nitrogen halkii nikkel. 18-8 nooca Cr-Ni ahama birta 301, 302, 304 (oo ay ku jiraan 321) ayaa ka dhigan in ka badan 50% wadarta wax soo saarka birta ah. Heerarkan birta ah waxay leeyihiin sifooyin dhammaystiran oo heersare ah sida iska caabbinta daxalka, guryaha makaanikada, guryaha heerkulka sare iyo hoose, sifooyinka habka, iyo sifooyinka qurxinta. Waxaa si weyn loogu isticmaalaa meelo kala duwan laga bilaabo madaniga ilaa militariga iyo qurxinta dhismaha madaniga ah. Qalabka guriga, qalabka jikada iyo maacuunta, gaadiidka, ilaalinta deegaanka, dhismaha dawladda hoose; duulista ciidamada, hawada sare, warshadaha nukliyeerka, maraakiibta; beeraha warshadaha ee kiimikada, bacriminta, batroolka, dhar, daabacaadda, warqad, tamarta. Shaxda 1 waxa ay taxaysaa taxanaha AISI200 ee manganese-ka caadiga ah ee ka kooban birta aan lahayn austenitic. Markaa daraasadihii hore ee 201, 202, 204, 205, 206 waxay u dhigantaa taxanaha Cr-Ni 301, 302, 304, 305, 316. Marka xigta, 211 ayaa loo sameeyay si loo isticmaalo darajooyinka birta ee yar-yar, Mn, iyo Cu-ku daray shaqada qabow. 201L, 201LN, iwm waa hagaajinta 201 si loo xalliyo dhibaatada daxalka cadaadiska intergranular.
Naytrojiin sare CrMnN austenitic birta aan lahayn waxay leedahay xoog sare, adag, caabbinta xirashada sare, non-magnetic, caabbinta daxalka iyo sifooyin kale, waxayna leedahay baahiyo kala duwan oo dhanka warshadaha ah. Mustaqbalka, waxaa jiri doona horumar ballaaran oo dhinacyada soo socda:
1. Birta CrMnNiN ee nitrogen-ka sare leh oo leh xoog sare, caabbinta daxalka sare iyo heerkulka hooseeya ee wanaagsan ayaa loo isticmaali karaa diyaaradaha, hawada hawada iyo maraakiibta leh ulaha waxqabadka wanaagsan, fiilooyinka, foornada, taarikada dhexdhexaadka ah, iyo taarikada khafiifka ah si ay u sameeyaan weelal, tuubooyinka, valves, Xargaha, iwm.
2. Xidho u adkaysta, daxalka u adkaysta, adag-adkeysiga sare iyo nitrogen-sare CrMnN austenitic steel steel waxay ku siin kartaa daxalka u adkaysta, qalabka farsamada iyo qalabka qalabka macdanta ee warshadaha macdanta.
3. Non-magnetic, xoogga sare, daxalka u adkaysta, nitrogen-sare CrMnMoN austenitic birta, kaas oo ku siin kara collars aan-magnetic ee beeraha saliidda, iyo kuwa aan magnetic ilaaliyaha siddo ee koronto dhaliyaasha warshadda. 4. Iska caabbinta daxalka sare, caabbinta daxalka iyo nitrogen sare CrNiMnMoN Austenitic birta aan lahayn waxay ku siin kartaa agab beddelayaasha kulaylka biyaha badda, qalabka nadiifinta biyaha badda, iyo aaladaha desulfurization gaaska qiiqa ee warshadaha xeebaha.
