Xa kufikwa kwizinto zanamhlanje ezisetyenziswa ekwakheni, ekuveliseni nasekubunjineli,yenziwe ngentsimbi eshayinayoIvelele njengenye yezona zinto zisebenziseka lula nezithembekileyo. Iqinile, ayidli mhlwa, ihlala ixesha elide, kwaye inobuhle obuhle kakhulu. Nangona kunjalo, omnye wemibuzo eqhelekileyo ebuzwa ziinjineli kunye nabathengi ngulo:"Ingaba intsimbi engagqwaliyo inemagnethi?"
Impendulo ayilula nje ngokuthi “ewe” okanye “hayi.”iipropati zemagnethi zentsimbi engagqwalixhomekeke kuyoukwakheka kweekhemikhali, isakhiwo sekristale, kunye nendlela yokucubungulaEli nqaku livela kwiI-SAKYSTELichaza isayensi engasemva kwemagnetism kwiintsimbi ezingasebenziyo, indlela amanqanaba ahlukeneyo aziphatha ngayo kwiindawo zemagnethi, kunye nesizathu sokuba ukuqonda ezi mpawu kubalulekile kwizicelo zakho.
1. Intshayelelo kwiNtsimbi engagqwaliyo
Yenziwe ngentsimbi eshayinayolusapho lwee-alloys ezisekelwe kwisinyithi eziqulethe ubuncinaneI-10.5% ye-chromium, eyenza iumaleko we-oxide ongasebenziyophezu komhlaba. Olu maleko lukhusela umhlwa kunye nokugqwala, nto leyo eyenza intsimbi engagqwaliyo ifaneleke kwiindawo ezinobungozi.
Ngaphandle kwe-chromium, ezinye izinto ezidibanisa i-alloy ezifana ne-chromiumi-nickel, i-molybdenum, i-manganese, i-nitrogen, kunye ne-titaniumzongezwa ukuphucula iipropati ezifana nokukwazi ukwakheka, amandla, kunye nokumelana nobushushu okanye iikhemikhali.
Nangona kunjalo, ezi zinto zifanayo zokudibanisa - ngakumbii-nickel kunye ne-chromium— ikwachaphazelaukuziphatha kwemagnethiyentsimbi.
2. Yintoni echaza iiMpawu zeMagnetic zeStainless Steel?
Iipropati yemagnethiyesinyithi imiselwa ikakhulu yiisakhiwo sekristale— ulungiselelo lweeathom ngaphakathi kwezinto. Kwiintsimbi ezinganyangekiyo, kukhoiintsapho ezintathu eziphambili zezakhiwo ezincinci, nganye ineempawu ezicacileyo zemagnethi:
| Uhlobo | Ulwakhiwo lwekristale | Ukuziphatha kweMagnetic | Amabanga aqhelekileyo |
|---|---|---|---|
| I-Ferritic | I-Cubic Ephakathi Komzimba (BCC) | Imagnethi | 409, 430 |
| I-Martensitic | I-Tetragonal Ephakathi Komzimba (BCT) | Imagnethi | 410, 420, 440C |
| I-Austenitic | I-Cubic Ephakathi Kobuso (FCC) | Ayinamagnethi | 304, 316, 310, 321 |
3. Indima yoLwakhiwo lwekristale
a) Iintsimbi ezingasebenziyo zeFerritic
Iintsimbi ezingenasici zeFerritic zineityhubhikhi egxile emzimbeni (BCC)isakhiwo sekristale esifana nesinyithi esicocekileyo, nto leyo ebenzainamandla kakhulu enomtsalaneZiqulathe i-chromium (10.5–18%) kodwa i-nickel incinci kakhulu okanye ayikho kwaphela. Ukungabikho kwe-nickel kuthetha ukuba isakhiwo sihlala siqinile kuzo zonke iiqondo zobushushu, ngaloo ndlela sigcina i-magnetism.
Imizekelo eqhelekileyo ibandakanya:
-
I-AISI 409– Isetyenziswa kwiinkqubo zokukhupha umoya kwiimoto
-
I-AISI 430– Ixhaphakile kwizixhobo zasekhitshini nakwizinto zokwakha ezisetyenziswa kakhulu
Iintsimbi zeFerritic ziyakwazi ukumelana nokugqwala kakuhle kwayei-ferromagnetic, oko kuthetha ukuba banokutsaleleka kakhulu kwiimagnethi.
b) Iintsimbi ezingasebenziyo zeMartensitic
Iintsimbi zeMartensitic nazoimagnethi, kunyei-tetragonal egxile emzimbeni (BCT)ulwakhiwo. La manqanaba adla ngokuba phezulu kwikhabhoni kwaye aphakathi kwi-chromium.unyango lobushushu kunye nokucima, isakhiwo siguquka sibe yi-martensite, eqinileyo nenemagnethi.
Amanqanaba aqhelekileyo e-martensitic aquka:
-
I-AISI 410– Intsimbi engagqwaliyo esetyenziselwa iinjongo ngokubanzi
-
I-AISI 420– Isetyenziselwa izixhobo zokusika kunye nezixhobo zotyando
-
I-AISI 440C– Eyaziwa ngokuba lukhuni kakhulu kwaye ingagugi
Ezi ntsimbi ziyadityaniswaamandla aphezulu, ubulukhuni, kunye nemagnetism, nangona zinokumelana nokugqwala okuphantsi kuneentlobo ze-austenitic.
c) Iintsimbi Ezingenasici zaseAustenitic
Iintsimbi ze-Austenitic, ezisetyenziswa kakhulu kwihlabathi liphela, zineityhubhiki ejonge ubuso (FCC)isakhiwo esiokungekho magnethikwimeko efakwe i-anneal. Ukongezwa kwei-nickel kunye ne-nitrogenizinzisa isigaba se-austenitic, isusa iipropati zemagnethi.
Imizekelo ibandakanya:
-
I-AISI 304 (EN 1.4301)– Eyona ntsimbi ixhaphakileyo engenasici
-
I-AISI 316 (EN 1.4401)– Yaziwa ngokumelana nokugqwala okuphezulu kwiindawo zaselwandle
-
I-AISI 310/321– Amanqanaba obushushu obuphezulu
Nangona ezi ntsimbi zihlala zingenamagnethi, zinokubaimagnethi encinci emva kokusebenza okubandayo(umz., ukugoba, ukuqengqeleka, okanye ukwenza). Oku kungenxaukuguqulwa okuncinci kwe-austenite ibe yi-martensitephantsi koxinzelelo.
4. Kutheni Ezinye Iintsimbi Ezingagqwaliyo ZineMagnetic Kanti Ezinye Zingenazo?
Umahluko ukho kwiulungiselelo lweathomu kunye nokujikeleza kwe-electronyesinyithi. Uzibuthe luvela kwiii-elektroni ezingadibaniyokwisakhiwo seathom esihambelana phantsi kwentsimi yemagnethi.
-

-
Iintsimbi ezingenasici zase-AusteniticNangona kunjalo, zinee-electron ezidibeneyo kwisakhiwo se-FCC esidityaniswe ngokuqinileyo, ezingashiyi zijikelezo zasimahla ukuze zilungelelaniswe — yiyo loo nto, azinamagnethi.
Ngamagama alula:
Ukuba intsimbi engagqwaliyo ine-nickel encinci okanye ayinayo, kusenokwenzeka ukuba ibe ne-magnetic. Ukuba ine-nickel, idla ngokuba yi-non-magnetic.
5. Udidi lweMagnetic lweeNsimbi ezingatyiwayo
Iintsimbi ezingenasici zingahlulwa zibe ngamaqela amathathu ngokusekelwe kwimpendulo yazo kwi-magnetic field:

b) Unyango lobushushu
Ukuqhoboshela kunye nokucima kunokutshintsha isakhiwo ukusuka kwi-austenitic ukuya kwi-martensitic, ngaloo ndlela kutshintsha indlela esebenza ngayo i-magnetic. Umzekelo, i-304 stainless steel inokuba yi-magnetic kancinci emva kokwakheka kobandayo kodwa inokulahlekelwa yile magnetism emva kokuqhoboshela.
c) Ukusebenza Ngobushushu
Ukuguqulwa koomatshini, okufana nokugoba, ukolula, okanye ukuqengqeleka, kunokubangelautshintsho lwesigaba se-martensitickwiintsimbi ze-austenitic, nto leyo edala amandla ombane abuthathaka.
d) Ukungcola kunye noxinzelelo olushiyekileyo
Uxinzelelo olushiyekileyo, uxinzelelo, kunye nokufakwa kwezinto ngaphakathi kunokutshintsha indlela ikristale ejikelezileyo ngayo, nto leyo echaphazela kancinci impendulo yemagnethi.

Kukhethwa amanqanaba e-Ferritic kunye ne-martensitic ngenxaiinkqubo zokukhupha umoya, izinto zokuhombisa, kunye nezinto zokubopha, apho imagnetism ingachaphazeli ukusebenza.
9. Ngaba iStainless Steel Ingaphulukana okanye Ifumane iMagneticism?
Ewe. Itini yentsimbi engatyiwayozuza amandla ombanexa kubanda kusebenza kwayeyilahlexa inyangwa ngobushushu.
-
Ukufumana iMagneticism:Ngexesha leenkqubo zokwenza izinto ezifanaumzobo onzulu, ukujikeleza, okanye ukuqengqeleka, ii-austenitic grades zinokuguquka kancinci zibe yi-martensite, zibe yimagnethi ebuthathaka.
-
Ukulahlekelwa yiMagneti:Ukutsalwa kwe-Annealing kumaqondo obushushu aphezulu (malunga ne-1050°C) kulandele ukupholisa okucothayo kubuyisela i-isakhiwo se-austenitic esingengomagnetic.
At I-SAKYSTEL, iinkqubo zonyango lobushushu ezichanekileyo zisetyenziselwa ukufezekisaiipropati zemagnethi ezihambelanayongokweemfuno zomthengi.
10. Iimfuneko zokuVuleka kweMagnetic kunye neMizi-mveliso
Iukuvuleka kwemagnethi (μ)intsimbi engagqwaliyo ilinganisa ukuba kulula kangakanani ukuba ikwazi ukuba nemagnethi. Ibonakaliswa xa ithelekiswa nendawo ekhululekileyo (μ₀).
-
Amanqanaba eFerritic kunye neMartensitic:μ ≈ 100–1000 (inamandla kakhulu emagnethi)
-
Amabanga e-Austenitic (afakwe i-annealed):μ ≈ 1.0–1.05 (ngokusisiseko ayisebenzi ngemagnethi)
Amashishini afana nei-aerospace, ukhuselo, kunye nemifanekiso yezonyangoidla ngokuchaza imida yokungena kwamanzi — ngesiqhelo i-μ ≤ 1.02 — ukuqinisekisa ukusebenza okungenamagnethi.
I-SAKYSTELinikezela ngeemveliso zentsimbi engagqwaliyo ezihlangabezanaiimfuneko zokungena kwamanzi kancinci, iqinisekiswe ngokuhlolwa okuneenkcukacha kunye nesatifikethi.
