Intsimbi ekhethekileyo, oko kukuthi, intsimbi ekhethekileyo, lolona hlobo lubalulekileyo lwentsimbi esetyenziswa kumashishini amaninzi oqoqosho lwesizwe, njengoomatshini, iimoto, imboni yomkhosi, iikhemikhali, izixhobo zasekhaya, iinqanawa, ezothutho, oololiwe kunye namashishini asakhulayo.Intsimbi ekhethekileyo iyisimboli esibalulekileyo sokulinganisa ukuba ilizwe linokuba yindlu yamandla yentsimbi.
Insimbi yenjongo ekhethekileyo ibhekisela kwamanye amacandelo asebenza phantsi kweemeko ezikhethekileyo kwaye aneemfuno ezikhethekileyo zetsimbi, ezifana nomzimba, iikhemikhali, oomatshini kunye nezinye iimpawu.
Iintsimbi zokusebenza ezikhethekileyo nazo zisemgangathweni okhethekileyo we-alloy steels.Ezi ntsimbi zibhekisa kwiintsimbi ezine-electromagnetic, optical, acoustic, thermal and electrochemical action kunye nemisebenzi.Ngokuqhelekileyo zisetyenziswa yintsimbi engatyiwa, intsimbi enganyangeki kubushushu, intsimbi yombane yesilicon, intsimbi esulungekileyo ye-elektroniki kunye neengxube ezichanekileyo ezahlukeneyo (i-alloys ezithambileyo zemagnethi, ezifana nemagnethi, ialloys elastiki, i-alloys eyandisiweyo, i-thermal double alloys, i-alloys yokumelana, izixhobo zebhetri eziphambili, njl. .)..
Intsimbi engatyiwayo ibizwa ngokuba yi-chromium kunye ne-nickel yokumelana nokugqwala kwayo.I-Chromium inozinzo oluphezulu lweekhemikhali kwaye inokwenza ifilimu eshinyeneyo kwaye ilukhuni yokucoca kwi-oxidizing medium;Ukongeza, xa umxholo we-chromium udlula i-11.7%, amandla e-electrode e-alloy anokwandiswa kakhulu, ngaloo ndlela athintele ngokufanelekileyo i-oxidation eyongezelelweyo ye-alloy.I-Nickel ikwangumququzeleli.Ukongezwa kwe-nickel kwintsimbi ye-chromium kunokuphucula ukuxhathisa kwe-corrosion ye-alloy kumajelo angenayo i-oxidizing.Xa umxholo we-chromium kunye ne-nickel uhlala, i-carbon content content kwintsimbi, bhetele ukuxhathisa ukubola.
Ukuxhatshazwa kwe-corrosion yensimbi engenasici nayo ihambelana nokufana kwesakhiwo se-matrix.Xa isisombululo esiqinileyo se-alloy senziwe, izinga lokubola kwentsimbi kwi-electrolyte lingancitshiswa ngokufanelekileyo.
I-Austenitic steel stainless yi-chromium-nickel series steel stainless steel kunye nesakhiwo esisodwa se-austenitic.Inokumelana ne-corrosion, ukuqina kobushushu obuphantsi, ukusetyenzwa koxinzelelo kunye ne-welding processability, non-magnetic, kwaye isetyenziswa ngokubanzi njengentsimbi yobushushu obuphantsi kunye nobushushu obuphantsi bentsimbi esebenza kumajelo eendaba ezonakalisayo.Intsimbi engeyiyo-magnetic;insimbi engenasici ye-ferritic iqulethe i-chromium, ehamba nenguqu yesigaba ngexesha lokufudumeza kunye nokupholisa, kwaye yinto esetyenziswa ngokuqhelekileyo i-wear-resistant material kwi-nitric acid kunye ne-nitrogen fertilizer industry;intsimbi ye-martensitic inomxholo ophezulu wekhabhoni kunye nokuqina okulungileyo.Isakhiwo se-martensitic sifunyenwe.Le ntsimbi inokuqina okulungileyo kunye nomxholo wekhabhoni ephantsi, kwaye ingasetyenziselwa ukwenza iindawo ezichasene nempembelelo ezisebenza kwimidiya ephazamisayo;ikhabhoni ephezulu isetyenziselwa ukwenza iziphethu, iibheringi, iiblade zotyando, njl.;inesigaba sesibini esixutywe isakhiwo se-austenite kunye ne-ferrite.Intsimbi engenasici ye-matrix yintsimbi ephindwe kabini, enezibonelelo zamandla aphezulu, ukuqina okuhle, kunye nokuchasana nokubola kwe-intergranular.Phakathi kwazo, i-00Cr18Ni5Mo3Si2 insimbi isetyenziselwa kakhulu ukuveliswa kobushushu kunye ne-condensers ekucoceni ioli, isichumisi, iphepha, i-petroleum, iikhemikhali kunye namanye amashishini, kwaye i-0Cr26Ni5Mo2 isetyenziselwa ukuveliswa kwezixhobo zokubola kwamanzi olwandle;I-molybdenum, i-niobium, i-lead, ithusi kunye nezinye izinto kwisigaba esinzima sibenza emva kokucinywa kunye nokuguga unyango, lunamandla aphezulu kunye nokuqina, kwaye lusetyenziselwa ukuvelisa imithombo, i-washers, i-bellows, njl.
Intsimbi yombane, ekwabizwa ngokuba yi-silicon steel, yi-iron-silicon binary alloy enomxholo wekhabhoni ongaphantsi kwe-0.05%.Ineempawu zokulahleka kwentsimbi encinci, amandla amancinci okunyanzeliswa, amandla ombane aphezulu kunye nokuqina kokufakelwa kwamagnetic, kwaye yenye yezinto ezisetyenziswa ngokuqhelekileyo ezithambileyo zamagnetic (kwixesha elifutshane okanye ukuphindaphindwa kwemagneti).Izinto eziphambili ezichaphazela ukusebenza kwentsimbi yombane ziyimichiza kunye nesakhiwo.I-silicon inempembelelo enkulu kwiipropati zemagnethi zentsimbi yombane.Xa i-3.0% Si yongezwa kwintsimbi ecocekileyo, ukunyanzeliswa kwamagnetic kwanda ngamaxesha angama-1.6-2, ilahleko ye-hysteresis iyancitshiswa ngama-40%, i-resistivity yanda ngamaxesha angama-4 (anganciphisa ilahleko yangoku eddy), kunye nenani elipheleleyo. ilahleko yentsimbi iyancitshiswa.Iphindwe kabini, kodwa ubulukhuni kunye namandla nawo anyuka ngokuphawulekayo.Ngokuqhelekileyo umxholo we-silicon awudluli kwi-4.5%, ngaphandle koko kunzima kakhulu kwaye kunzima ukusetyenzwa.Ubukho bokungcola okuyingozi (N, C, S, O, njl.) kuya kubangela ukuphazamiseka kwe-lattice yentsimbi, ukwandisa uxinzelelo, kunye nokuthintela inkqubo yemagnetization, ngoko umxholo wokungcola kufuneka ulawulwe ngokungqongqo.
Intsimbi yeSilicon isetyenziswa ikakhulu kumashishini ombane anjengeemoto, iinguqu, izixhobo zombane, kunye nezixhobo zombane.Uninzi lufakwe kwi-0.3, 0.35, 0.5 sheets, kubandakanywa ukuqengqeleka okushushu kunye nokubanda.kubanda kuqengqeleka
