Insimbi engagqwali impahla:

Insimbi engagqwali iwuhlobo lwempahla, inokukhanya kwesibuko esiseduze, ithinte kanzima futhi ibanda, ingeyezinto zokuhlobisa i-avant-garde, inokumelana nokugqwala okuhle kakhulu, ukubumba, ukuhambisana nokuqina nezinye izici zochungechunge, ezisetshenziswa embonini esindayo. , imboni elula, imboni yempahla yasendlini kanye nokuhlobisa izakhiwo nezinye izimboni.

Insimbi engagqwali engamelana ne-asidi ebizwa ngokuthi insimbi engagqwali, yakhiwe ngensimbi engagqwali nensimbi engazweli nge-asidi izingxenye ezimbili, ngamafuphi, ingamelana nokugqwala kwensimbi okusemoyeni okubizwa ngokuthi insimbi engagqwali, futhi ingamelana nokugqwala kwamakhemikhali okuphakathi kwensimbi okubizwa nge-acid resistant steel. ukukhuluma, okuqukethwe kwe-chromium ye-Cr kungaphezu kuka-12% wensimbi inezici zensimbi engagqwali.

Ukuhlukaniswa kwensimbi engagqwali:

Kunezindlela eziningi zokuhlukaniswa kwensimbi engagqwali, phakathi kwazo ezivame kakhulu yilezi ezilandelayo.

Ukuhlukaniswa kwesakhiwo se-metallographic:

Ingahlukaniswa ngensimbi engagqwali ye-austenitic, insimbi engagqwali ye-ferrite, insimbi engagqwali ye-martensitic, insimbi engagqwali e-duplex, imvula eyenza insimbi engagqwali ibe lukhuni.

Isigaba sokwakheka kwamakhemikhali:

Ngokuyisisekelo ingahlukaniswa ngensimbi engagqwali ye-chromium (njengochungechunge lwe-ferrite, isistimu ye-martensite) nensimbi engagqwali ye-chromium nickel (njengesistimu ye-austenite, uchungechunge olungavamile, uchungechunge oluqinile lwezulu) amasistimu amabili.

Ngokusho kohlobo lokumelana nokugqwala:

Ingahlukaniswa ngensimbi engagqwali ekwazi ukumelana nokugqwala, insimbi engagqwali engagqwali, i-intergranular corrosion resistant stainless steel, njll.

Kuhlukaniswa ngezici zokusebenza:

Ingahlukaniswa ngensimbi engagqwali yokusika yamahhala, insimbi engagqwali engeyona enozibuthe, izinga lokushisa eliphansi lensimbi engagqwali, insimbi engenasici.

Cishe kunezinhlobo eziyi-100 zensimbi engagqwali ezifakwe emazingeni ahlukahlukene emhlabeni, futhi ngenqubekela phambili yesayensi nobuchwepheshe kanye nokuthuthukiswa kwezimboni nezolimo, amamaki amasha ensimbi engagqwali nawo ayakhula. Ngebanga elaziwayo lensimbi engagqwali. , okulingana nayo i-chromium [Cr] kanye nokulingana kwe-nickel [Ni] ingabalwa ngokuvumelana nokwakheka kwamakhemikhali ayo, futhi isakhiwo esincane nezici zensimbi zingalinganiselwa cishe kusetshenziswa ishadi le-microstructure yensimbi engenasici ye-Schaeffler-Delong.

Ukuhlukaniswa kwe-matrix:

1, insimbi engagqwali ye-ferrite.I-Chromium 12% ~ 30%.Ukumelana nokugqwala kwayo, ukuqina kanye nokushisela kuyakhula ngokunyuka kokuqukethwe kwe-chromium, futhi ukumelana nokugqwala kwe-chloride yayo kungcono kunezinye izinhlobo zensimbi engagqwali.

2. Insimbi engagqwali ye-Austenitic.Iqukethe i-chromium engaphezu kuka-18%, i-nickel engaba ngu-8% kanye nenani elincane le-molybdenum, i-titanium, i-nitrogen nezinye izakhi.Ukusebenza okuhle okuphelele, ukumelana nokugqwala ezinhlobonhlobo zemidiya.

3. I-Austenite-ferrite duplex steel stainless.Inobuhle be-austenite ne-ferrite insimbi engagqwali, futhi ine-superplasticity.

Insimbi engagqwali ye-Martensitic.Amandla aphezulu, kodwa ipulasitiki empofu kanye nokushisela.
