Ngaba 304 Steel Steel Magnetic? Ukuphonononga iiPropati zayo zeMagnetic kunye nezicelo

Intsimbi engagqwaliyo yinto ethambileyo esetyenziswa kakhulu ekwakheni, kwiimoto, kwizixhobo zasekhitshini, nakwiimveliso zonyango. Phakathi kweendidi zayo ezininzi, intsimbi engagqwaliyo engama-304 ithandwa kakhulu ngenxa yokuqina kwayo kunye nokukwazi kwayo ukumelana nokugqwala. Nangona kunjalo, umbuzo ufika engqondweni rhoqo- Ngaba intsimbi engagqwali engama-304 inamandla kanobom? Eli phepha liza kuxoxa ngemagnetism yeentlobo ezingama-304 zentsimbi engagqwaliyo, kubandakanya ukusebenzisana kwayo nezinye iimagnethi kunye nokusetyenziswa kwayo ekwakheni iinqanawa zaselwandle. Olu hlobo lolwazi malunga neempawu zemagnethi zale nqanaba lentsimbi engagqwaliyo lunceda kakhulu ekumiseleni ukusebenza kwenqanaba. Inceda ukwenza ukhetho olufanelekileyo malunga nokwakheka kwezinto. Ngoko ke, makhe sihlolisise intsimbi engagqwali engama-304 ngokweenkcukacha size sizame ukuqonda ukuba kutheni ingeyonto inamandla kanobom.

Yintoni eyenza i-304 yeNsimbi eNgatyiwayo ingabi yiMagnetic?

Ubume be-athomu ye-304 yensimbi engenasici ichaza iimpawu zayo ezingenamagnetic. Eli nqanaba lentsimbi engenasici linomxholo ophezulu wechromium owenza umaleko weoksidi yokwenziwa kumphezulu, nto leyo inika ukuxhathisa okuhle kakhulu ekudlekeni. Kukwanjalo kumxholo we-nickel okwanceda ukuba izinto eziphathekayo zingabinamagnetic. Isakhiwo se-austenitic sensimbi, egcinwe yi-athomu ye-nickel, i-FCC, inqande ukudalwa kwemimandla yamagnetic. Ngaloo ndlela, ubukho be-manganese kunye nokungabikho kwesinyithi kubangela ukuba i-stainless steel 304 ibe yi-non-magnetic. Kuyaphawuleka ukuba apho i-304 insimbi engenasici kuthiwa ayiyo-magnetic, inokuba yimagnethi kancinane emva kokusebenza okubandayo okanye ezinye iindlela zokuvelisa. Nangona kunjalo, i-magnetism enjalo ithathwa njengobuthathaka kwaye ayinayo impembelelo ebalulekileyo kwi-non-magnetism yayo.

Ncedisa kwi-Austenitic Structure Comprehension

I-304 yentsimbi engatyiwayo inokuqinisekiswa njengengeyo-magnetic; kunjalo, inyathelo lokuqala ekusekweni ukuba ukuqonda isakhiwo yayo austenitic. Ukulungelelaniswa kwe-athomu yeli nqanaba lentsimbi luhlobo lokuba ne-cubic (FCC) ye-face-centered cubic lattice, kwaye ukwenzeka kwe-nickel kuzinzisa oku. Ubuninzi bechromium obuqulethwe kule ntsimbi ye-304 isenza i-passive oxide layer kumphezulu wayo oluncedo kakhulu ekuxhathiseni ukubola. Ukongeza, ukungabikho kwezinto zamagnetic, umzekelo, i-iron, iphinda ichaze ukuba kutheni ingabonisi iimpawu zamagnetic. Kukhankanyiwe ukuba intsimbi equlathe i-304 ibonisa idigri ye-magnetism nasemva kokuhamba kweenkqubo ezifana nokusebenza okubandayo okanye iinkqubo ezithile zokuvelisa, kodwa kunjalo, ithathwa njengentsimbi engeyiyo-magnetic, kwaye ke, iipropati ezifunwayo zihlala zilungile.

Ukubaluleka kweNickel kwi-Austenitic Stainless Steel

Iimpawu ze-Nickel zibaluleke kakhulu kwiipropati ze-austenitic stainless steel nonmagnetic. Ubukho bayo kwi-alloy bugcina i-face-centered cubic (FCC) isakhiwo selathisi, esinoxanduva lophawu lwe-nonmagnetic. Ngenxa yobukho be-nickel, umxholo ophezulu we-chromium kunye nomgangatho we-oxide owenziweyo owenziwe phezu komhlaba uqinisekisa umgangatho ophezulu kakhulu wokumelana nokubola. Ngokwesiqhelo, i-304 ihlelwa njengentsimbi engenamagnetic kodwa inokubonisa intsalela yemagnethi kwiimeko ezithile, ezinje ngexesha elibandayo lokusebenza okanye iinkqubo ezithile zokuvelisa. Nangona kunjalo, le magnetism ibuthathaka kwaye ayitshintshi kakhulu impawu ezingeyomagnetic zezinto. Iinkcukacha ezithe ngqo malunga nemigaqo yeeparamitha zobugcisa, kunye nezizathu zazo, ziyafumaneka kuncwadi olufanelekileyo kunye neenkcukacha zemathiriyeli.
