Ingabe i-400 Series Stainless Steel Rust?

Insimbi engagqwali idumile ngokumelana kwayo nokugqwala, ukuqina kwayo, kanye nokukhanga kwayo ngobuhle. Kodwa-ke, akuwona wonke amazinga ensimbi engagqwali anikeza izinga elifanayo lokuvikelwa ekugqwaleni. Omunye wemibuzo evame ukubuzwa phakathi konjiniyela, abakhi bezakhiwo, kanye nabakhiqizi uthi:Ingabe insimbi engagqwali yochungechunge lwe-400 iyagqwala?

Impendulo emfushane ithi:yebo, insimbi engagqwali engu-400 yochungechunge ingagqwala, ikakhulukazi ngaphansi kwezimo ezithile zemvelo. Nakuba isanikeza ukumelana nokugqwala okungcono kunensimbi yekhabhoni, ukusebenza kwayo kuncike ebangeni elithile, ukwakheka, kanye nendawo yesevisi. Kulesi sihloko, sizogxila ku-ukumelana nokugqwala kwensimbi engagqwali engu-400 yochungechunge, hlola izici ezithonya ukusebenza kwayo, bese unikeza isiqondiso sokuthi ingasetshenziswa kuphi futhi kanjani ngempumelelo.

Njengomhlinzeki othembekile wemikhiqizo yensimbi engagqwali,i-sakysteelilapha ukuzokusiza uqonde ukuthi ungenza kanjani izinqumo ezinolwazi lapho ukhetha ibanga elifanele lephrojekthi yakho.

1. Ukuqonda i-Stainless Steel yochungechunge lwe-400

Izinsimbi ezingagqwali ezingu-400 ziwumndeni wezinhloboi-ferritic kanye ne-martensiticama-alloy ensimbi engagqwali. Ngokungafani nochungechunge lwe-austenitic 300 (njengo-304 no-316), uchungechunge lwe-400 ngokuvamileiqukethe i-nickel encane noma ayikho nhlobo, okuthinta kakhulu ukumelana nokugqwala.

Amamaki avamile ochungechunge lwama-400 afaka:

• 409: Isetshenziswa ezinhlelweni zokukhipha ugesi ezimotweni

• 410: Ibanga le-martensitic elijwayelekile

• 420: Yaziwa ngokuqina okuphezulu kanye nezicelo zezitsha

• 430: Ihlobisa futhi ayigqwali ukusetshenziswa endlini

• 440: I-carbon ephezulu, izinga eliqina elisetshenziswa kuma-blades namathuluzi

La mabanga ngokuvamile aquketheI-chromium engu-11% kuya ku-18%, eyakha ungqimba lwe-oxide olungasebenzi olusiza ukumelana nokugqwala. Kodwa-ke, ngaphandle kwethonya elivikelayo le-nickel (njengoba kubonwe ochungechungeni lwe-300), lolu ngqimba luyi-ukungazinzile kahlengaphansi kwezimo ezinolaka.

2. Kungani Insimbi Engagqwali Yochungechunge Lwezingu-400 Ingagqwala?

Kunezici eziningana ezithonyaukuthambekela kokugqwalayensimbi engagqwali yochungechunge lwama-400:

a) Okuqukethwe Okuphansi Kwe-Nickel

I-Nickel ithuthukisa ikhwalithiukuzinza kwesendlalelo se-chromium oxide esingasebenziokuvikela insimbi engagqwali ekugqwaleni. Ukungabikho kwe-nickel kumagreyidi angu-400 ochungechunge kubenza babeukumelana nokugqwala okuncaneuma kuqhathaniswa nochungechunge lwama-300.

b) Ukungcoliswa Komphezulu

Uma kuvezwa ku:

• Ama-ion e-chloride (isb., avela emanzini anosawoti noma kusawoti wokuhlanza)

• Ukungcola kwezimboni

• Ukuhlanza okungalungile noma izinsalela zokwenziwa
  ungqimba lwe-chromium oxide oluvikelayo lungaphazamiseka, okubangelaukugqwala kwemigodi or izindawo zokugqwala.

c) Ukunakekelwa Okubi noma Ukuchayeka Okubi

Ezindaweni zangaphandle ezinomswakama ophezulu, imvula ene-asidi, noma i-spray kasawoti, insimbi engavikelekile yochungechunge lwe-400 isengozini enkulu yokugqwala. Ngaphandle kokwelashwa okufanele kwendawo, ukudaya nokugqwala kungenzeka ngokuhamba kwesikhathi.

3. Umehluko Phakathi Kwamagredi e-Ferritic ne-Martensitic

Uchungechunge lwe-400 luhlanganisa kokubilii-ferriticfuthii-martensiticizinsimbi ezingagqwali, futhi ziziphatha ngendlela ehlukile maqondana nokumelana nokugqwala.

I-Ferritic (isb., 409, 430)

• Uzibuthe

• Ukumelana nokugqwala okumaphakathi

• Kuhle ezindaweni zangaphakathi noma ezingcolisa kancane

• Ukwakheka okungcono kanye nokushibilika

I-Martensitic (isb., 410, 420, 440)

• Iqina ngokwelashwa ngokushisa

• Okuqukethwe okuphezulu kwekhabhoni

• Amandla aphezulu kanye nokumelana nokuguguleka

• Ayimelani nokugqwala kakhulu kune-ferritic ngaphandle kokuthi ingasebenzi noma imbozwe

Ukuqonda ukuthi yiliphi iklasi elincane olisebenzisayo kubalulekile ekulinganiseni ukusebenza kokugqwala.

4. Izicelo Zangempela kanye Nokulindela Kwazo Kokugqwala

Iukukhetha ibanga lochungechunge lwama-400kumele ivumelane neukuchayeka kwemvelo kohlelo lokusebenza:

• 409 Insimbi Engagqwali: Isetshenziswa njalo ezimotweni zokukhipha ugesi. Ingagqwala ngokuhamba kwesikhathi kodwa inikeza ukumelana nokugqwala okwamukelekayo ezindaweni ezishisa kakhulu.

• 410 Insimbi Engagqwali: Isetshenziswa ezintweni zokusika, ama-valve, izibambo. Ithambekele ekugqwaleni ngaphandle kokuphazamiseka komhlaba.

• 430 Insimbi Engagqwali: Ithandwa kakhulu ngezinto zasekhishini, ezitsheni, kanye namaphaneli okuhlobisa. Iyakwazi ukumelana nokugqwala endlini, kodwa ingagqwala uma isetshenziswa ngaphandle.

• Insimbi Engagqwali engu-440: Ukuqina okuphezulu kwama-blade nezinsimbi zokuhlinza, kodwa kulula ukuzithola ezindaweni ezimanzi uma kungaqedwanga kahle.

At i-sakysteel, seluleka amakhasimende ngebanga elifanele kakhulu le-400 series kuye ngokuthi basengozini kangakanani emvelweni kanye nokulindela ukugqwala.
