Iintsimbi ezingenasici ze-Super austenitic ziye zavela njengenye yezona zinto ziphambili nezithembekileyo kwicandelo le-metallurgy. Ezi ntsimbi zibizwa ngokuba zii-alloys, ezidume ngokumelana kwazo nokugqwala okugqwesileyo, amandla aphezulu, kunye nokukwazi ukumelana nobushushu obugqithisileyo, ziye zaba yimfuneko kumashishini afana nokucubungula iikhemikhali, i-aerospace, kunye nokusetyenziswa kolwandle. Uphuhliso lwentsimbi engenasici ye-super austenitic luhambo olunomdla lokuvelisa izinto ezintsha kunye nokuqhubela phambili kwesayensi. Kweli nqaku, siza kuhlola imbali, iipropati, ukusetyenziswa, kunye nekamva leentsimbi ezingenasici ze-super austenitic, ngelixa sikwagxininisa indlelaINTSIMBI E-SAKYiyaqhubeka nokubonelela ngezixhobo ezikumgangatho ophezulu zokusetyenziswa kwemizi-mveliso okufunekayo.
Yintoni iSuper Austenitic Stainless Steel?
Intsimbi engagqwaliyo ye-Super austenitic luhlobo oluphezulu lwentsimbi engagqwaliyo ye-austenitic. Olu didi lwentsimbi lwahlulwe kukumelana kwayo nokugqwala okuphezulu, ingakumbi kwiindawo ezine-asidi eninzi okanye i-chloride eninzi. Iintsimbi ezingagqwaliyo ze-Austenitic zihlala zibonakaliswa yisakhiwo sazo sekristale ye-cubic (FCC) esisebusweni, esinika ukuqina kunye nokuguquguquka okuhle kakhulu kumaqondo obushushu aphantsi.
Iintsimbi ezingenasici ze-Super austenitic zinomxholo ophezulu we-alloy, zihlala zinenani elikhulu le-nickel, i-molybdenum, kunye ne-nitrogen, ukubonelela ngokumelana okukhulu nokugqwala, ukuqhekeka koxinzelelo, kunye ne-oxidation yobushushu obuphezulu. Ezi zinto ziphuculiweyo zenza iintsimbi ezingenasici ze-super austenitic zifaneleke ngokukodwa kwizicelo ezifuna ukusebenza okugqwesileyo phantsi kweemeko ezinzima.
Uphuhliso Lokuqala Lwentsimbi Engagqwaliyo Yase-Austenitic
Intsimbi engagqwaliyo yase-Austenitic yaqala ukuphuhliswa ekuqaleni kwenkulungwane yama-20, nto leyo eyaphawula impumelelo enkulu kwicandelo lesayensi yezinto. Iintsimbi ezingagqwaliyo zase-Austenitic zokuqala, ezifana ne-304 kunye ne-316 grades, zenzelwe ukudibanisa ukumelana nokugqwala kwentsimbi engagqwali kunye nokuqina kunye nokuguquguquka kwentsimbi yekhabhoni.

Izinto ezibalulekileyo ekuphuhlisweni kweSuper Austenitic Stainless Steel
Ii-1950s: Izinto Ezintsha Zasekuqaleni kunye Novavanyo
Ibali le-super austenitic stainless steel laqala ngeminyaka yoo-1950 xa izazinzulu kunye neenjineli zaqala ukuzama ii-alloys ezinokumelana ngcono nokugqwala kwemingxuma kunye nokuqhekeka, ingakumbi kwishishini lokucubungula iikhemikhali. Imizamo yokuqala yayigxile ekwandiseni umxholo we-chromium ukuphucula ukumelana nokugqwala, kodwa oku kukodwa kwakunganelanga ukuhlangabezana neemeko ezinzima zeendawo ezinobundlongondlongo, ezifana nezo zifunyanwa emanzini olwandle kunye neekhemikhali ze-asidi.
Enye yeempumelelo zokuqala ekuphuhlisweni kwentsimbi engagqwaliyo ye-super austenitic yeza nokongezwa kwamanqanaba aphezulu e-nickel kunye ne-molybdenum, nto leyo eyanyusa kakhulu ukumelana kwezinto kwi-corrosion ebangelwa yi-chloride. Ezi klasi zokuqala ze-super austenitic, ezidla ngokubizwa ngokuba “ziintsimbi ezingagqwaliyo ze-high-nickel,” zimele inyathelo elikhulu phambili kwizinto ezingagqwaliyo.
Iminyaka yoo-1960: Indima yeMolybdenum kunye neNitrogen
Ngeminyaka yoo-1960, abaphandi babesele beyibonile ukubaluleka kwe-molybdenum kunye ne-nitrogen ekwandiseni ukumelana nokugqwala kweentsimbi ezingenanto. I-Molybdenum yabonakala iphumelela kakhulu ekuthinteleni ukugqwala kwemigodi, oluluhlobo oluqhelekileyo lokugqwala okwenzeka kwiindawo ezityebileyo nge-chloride, njengamanzi olwandle kunye neekhemikhali zoshishino. Kwelinye icala, i-nitrogen yafunyanwa iphucula amandla kunye nokuqina kwe-alloy, okwenza ukuba imelane ngakumbi nokuqhekeka kokugqwala.
Iintsimbi ezingenasici ze-Super austenitic ezine-molybdenum (ngesiqhelo ziphakathi kwe-4-7%) kunye ne-nitrogen zasasazeka kakhulu ngeli xesha. Ezi zinto zaqala ukuthandwa kakhulu kumashishini afana nemveliso yeoyile negesi elwandle, apho izinto zaziphantsi koxinzelelo olukhulu kunye neendawo ezirhabaxa.
Ii-1970s: Uphuhliso lweeGrade zokuQala zeSuper-Austenitic
Kwiminyaka yoo-1970, kwaqaliswa amanqanaba okuqala orhwebo e-super austenitic stainless steel. La manqanaba ayequka amanqanaba afana ne-904L, eyayine-25% ye-nickel kunye ne-4.5% ye-molybdenum, kwaye ayenzelwe ukumelana nokugqwala kwemingxuma kunye nokuqhekeka kwemingxuma. La manqanaba akwabonakalise ukumelana okuhle kakhulu ne-sulfuric acid kunye nezinye iikhemikhali ezirhabaxa, nto leyo eyazenza zafaneleka ukusetyenziswa kumashishini okucubungula iikhemikhali kunye namayeza.
Uphuhliso lwezi ntsimbi luphawule ukuqala kokusetyenziswa ngokubanzi kwentsimbi engagqwali ye-super austenitic kwizicelo zokusebenza okuphezulu. Amandla entsimbi yokumelana namaqondo obushushu aphezulu kunye neendawo ezirhabaxa ayenze yaba yinto ekhethwayo kumashishini afana neenqwelo-moya kunye nokuveliswa kwamandla.

Kwiminyaka yoo-1980, uphuhliso lweentsimbi ezingenasici ze-super austenitic lwaqhubeka luhambela phambili, luqhutywa kukuqhubela phambili kubuchwepheshe bokuvelisa kunye nokwakheka kwe-alloy. Ukuqaliswa kobuchule obuphambili bokunyibilikisa kunye nokukhupha kwavumela ukuveliswa kwee-alloys ezifanayo nezikumgangatho ophezulu, nto leyo eyakhokelela ekuphuculweni kweempawu zoomatshini kunye nokusebenza ngcono ngokubanzi kwiindawo ezifuna amandla.
Ngeli xesha, izinto ezenziwe nge-alloy zeentsimbi ezingenasici ze-super austenitic zaphuculwa ngakumbi, ngamanqanaba aphezulu e-nickel kunye ne-molybdenum, kunye nokungeniswa kwezinye izinto ezifana ne-copper kunye ne-tungsten. Ezi zongezo ziphucule ukumelana nokugqwala, ngakumbi kwiindawo apho intsimbi yayichatshazelwa yi-ions ye-chloride, kwaye zabonelela ngokumelana okuphuculweyo kokuqhekeka kokugqwala kunye nokugqwala kwe-crevice.
Iminyaka yoo-1990 nangaphaya: Ukuqhubekeka nokuHlaziywa kunye nokuSebenza
Ngeminyaka yoo-1990, iintsimbi ezingenasici ezisetyenziswa kakhulu kwi-super austenitic zazisele zibaluleke kakhulu kumashishini amaninzi. Abaphandi kunye neenjineli baqhubeka nokuphucula umxube we-alloy ukuze bahlangabezane neemfuno ezikhulayo zamashishini afana neoyile negesi engaphandle kolwandle, amandla enyukliya, kunye nokucutshungulwa kweekhemikhali.
Iindidi ezintsha, ezifana ne-254SMO, equlethe i-6% ye-molybdenum, zaphuhliswa ukuze zibonelele ngokumelana nokugqwala kunye nokuhlaselwa okuqhelekileyo kwiindawo ze-chloride. Ezi zinto zazisetyenziswa kakhulu kwizityalo zokususa ityuwa emanzini olwandle, kunye nokucubungula iikhemikhali kunye nokusetyenziswa kwe-petrochemical.
Uphando oluqhubekayo kunye nophuhliso lweentsimbi ezingenasici ze-super austenitic kukhokelele ekusetyenzisweni kwazo kwiindawo ezikhethekileyo ngakumbi, kubandakanya i-aerospace, ukuveliswa kwamandla, kunye nezixhobo zoshishino ezisebenza kakuhle. Iintsimbi ezingenasici ze-super austenitic zanamhlanje zinokufumaneka kwiindlela ezahlukeneyo zokumisela, ukusuka kwiityhubhu ezidityanisiweyo kunye neepayipi ukuya kwizinto ezintsonkothileyo zesakhiwo, ngenxa yokudityaniswa kwazo kakuhle, ukwakheka, kunye nokumelana nokugqwala.
