Njengesixhobo esiqhelekileyo sokuphatha izixhobo zokupheka ze-SS, intsimbi engagqwali ye-ferritic yebanga lama-430 ilawula uluhlu oluphakathi.isixhobo sokuphekaukwenziwa kwexabiso elilinganayo kunye nokusebenza ngokomzimba. Iingenelo zayo eziphambili ziquka ukumelana okuhle nobushushu obuphezulu ukugcina ubushushu bokupheka bexesha elifutshane ukuya kuthi ga kwi-450℃, ukuphepha ngempumelelo ukuguqulwa kobushushu ngexesha lokusetyenziswa kwesitovu. Ngaphandle kokwakheka kwe-nickel ebizayo, i-430 inciphisa izinto ezikrwada zibiza kakhulu xa kuthelekiswa nentsimbi engagqwali ye-304 kwaye inesimo esihle soomatshini sokuthwala ngesandla. Umxholo we-chromium yendalo wenza ifilimu engasebenziyo yokulwa nomhlwa ukuthintela ukugqwala kwekhitshi okufumileyo imihla ngemihla, ihambelana neemfuno ezisisiseko zokumelana nomhlwa kwiziphatho zeembiza.
Nangona kunjalo, iingxaki ezikhoyo zithintela ukusetyenziswa kwayo okuphezulu. Ulwakhiwo lwayo lwe-ferritic luzisa amandla ombane acacileyo kunye nokumelana nokugqwala okungaphantsi kokumelana nentsalela yesobho enetyuwa nexesha elide; ukuntywila ixesha elide kubangela amabala omhlwa asekuhlaleni ngokulula. Ukuguquguquka okungalunganga kobushushu obuphezulu kukhokelela kwiingozi zokuqhekeka phantsi koxinzelelo olugqithisileyo lokunyathela.
Ukugqitywa komphezulu okuthandwayo kwesiciko sesiphatho sezixhobo zokupheka ze-SSukupolisha umgca weenwelekwayeUkugqitywa kwesipili se-8Knge-lamination yefilimu ekhuselayo. Ukuhamba kwemveliso eqhelekileyo kuqulathe ukusika okungenanto, ukunyathela ngokuchanekileyo, ukususa imiphetho, ukubumba ngobushushu obuphezulu, ukupolisha umphezulu kunye nokusonga ifilimu ekhuselayo. Ubunzima bokuvelisa obuphambili bugxile ekuqineni kokupolisha okufanayo: iziphatho zezixhobo zokupheka ezincinci zidla ngokugoba ngexesha lokusila, ngelixa ukugqitywa kwesipili kufuna ukugoba okuncinci kwamanqanaba amaninzi ukuze kususwe imikrwelo emincinci, okunciphisa kakhulu isivuno semveliso egqityiweyo. Ulawulo oluqinileyo lobushushu lukwabalulekile ukuthintela ukuguquguquka koxinzelelo lobushushu kwiziphatho ezenziweyo.
Ukugxila kwiIsiphatho sezixhobo zokupheka ze-SSukuveliswa ngobuninzi, i-AISI 430 ferritic stainless steel izisa imiqobo emininzi yokucubungula kuyo yonke imveliso.
Okokuqala, ukuguquguquka okungekuhle kobushushu begumbi kubangela ukuqhekeka ngokulula ngexesha lokunyathela nokugoba. Ulwakhiwo lwekristale ye-ferritic ye-430's alunazo i-nickel yokuqina; iziphene ezibhityileyo zesiphatho zihlala zahlukana kwiikona ezigobileyo phantsi kokwakheka okubandayo, okunyusa izinga lokuqhekeka ngokubonakalayo. Ukufakelwa kwangaphambili kongeza iindleko ezongezelelweyo zemveliso ukuphucula i-plasticity.
Okwesibini, ukugqitywa komphezulu okulinganayo kunzima kwiindlela zokunyanga iinwele okanye izipili. Ubulukhuni bomphezulu obungalinganiyo bezinto ezisetyenzisiweyo bukhokelela ekukhanyeni okungaguqukiyo. Izibambo ezinodonga oluncinci ziyaguquguquka phantsi koxinzelelo lokusila, nto leyo eyenza kube nzima ukufikelela kwimilo efanayo yesipili okanye neenwele kwiibhetshi ezinkulu.
Okwesithathu, ukuthembeka kokuwelda ngezixhobo zokupheka kusanzima. Ukwahlulwahlulwa okuphezulu kwe-chromium kwiindawo zokuwelda kubangela ukuncipha kwe-chromium, nto leyo ebangela ukunganyangeki kokugqwala kunye nokugqwala okulula kumalungu emva kokusetyenziswa ixesha elide ekhitshini. Ubushushu obugqithisileyo bokuwelda bukwatshintsha izibambo ezigqityiweyo.
Ngaphandle koko, ukumelana nokugqwala okungazinzanga phantsi kweendawo zasekhitshini ezifumileyo nezineasidi kusisiphene esifihlakeleyo esihlala sihleli. Ifilimu yendalo engasebenziyo kwi-430 iyaqhekeka kwintsalela yokutya enetyuwa, ifuna iinkqubo zokukhusela umphezulu ukuze ihlangabezane nemigangatho yokulwa nokugqwala kwizixhobo zokupheka.
