Ingabe i-400 Series Stainless Steel Rust?

Insimbi engagqwali ibungazwa ukumelana nokugqwala kwayo, ukuqina, nokukhanga kobuhle. Nokho, akuwona wonke amamaki ensimbi engenasici anikeza izinga elifanayo lokuvikela ekugqwaleni. Omunye wemibuzo evame ukubuzwa phakathi konjiniyela, abaklami bezakhiwo, kanye nabakhiqizi ngu:Ingabe 400 uchungechunge lwensimbi engagqwali ukugqwala?

Impendulo emfushane ithi:yebo, 400 uchungechunge insimbi engagqwali kungaba nokugqwala, ikakhulukazi ngaphansi kwezimo ezithile zemvelo. Nakuba isanikeza ukumelana nokugqwala okungcono kune-carbon steel, ukusebenza kwayo kuncike ebangeni elithile, ukwakheka, nendawo yesevisi. Kulesi sihloko, sizocwilisa ku-ukumelana nokugqwala kwe-400 uchungechunge lwensimbi engagqwali, hlola izici ezithonya ukusebenza kwayo, futhi unikeze umhlahlandlela wokuthi ungayisebenzisa kuphi futhi kanjani ngempumelelo.

Njengomhlinzeki othembekile wemikhiqizo yensimbi engagqwali,sakysteelilapha ukuze ikusize uqonde ukuthi ungenza kanjani ukukhetha unolwazi lapho ukhetha ibanga elifanele lephrojekthi yakho.

1. Ukuqonda 400 Series Stainless Steel

Uchungechunge lwama-stainless steels angu-400 luwumndenii-ferritic ne-martensiticama-alloys ensimbi engagqwali. Ngokungafani nochungechunge lwe-austenitic 300 (njenge-304 ne-316), uchungechunge lwama-400 ngokuvamileiqukethe i-nickel encane noma ayikho nhlobo, okuthinta kakhulu ukumelana nokugqwala.

Amamaki ochungechunge ajwayelekile angama-400 afaka:

• 409: Isetshenziswa kumasistimu wokukhipha umoya wezimoto

• 410: Ibanga le-martensitic lenhloso evamile

• 420: Kwaziwa ngobulukhuni obuphezulu kanye nezicelo zokusika

• 430: Iyahlobisa futhi imelana nokugqwala ukuze isetshenziswe endlini

• 440: Ikhabhoni ephezulu, ibanga eliqinile elisetshenziselwa izindwani namathuluzi

Lawa mabanga ngokuvamile aqukethe11% kuya ku-18% chromium, okwakha ungqimba lwe-passive oxide olusiza ukumelana nokugqwala. Kodwa-ke, ngaphandle kwethonya elivikelayo le-nickel (njengoba kuboniswe ochungechungeni lwe-300), lolu ungqimba luyiuzinzile kancanengaphansi kwezimo ezinolaka.

2. Kungani 400 Series Stainless Steel Rust?

Ziningana izici ezithonyaukugqwala ukuthambekelaof 400 uchungechunge lwensimbi engagqwali:

a) Okuqukethwe kwe-Nickel okuphansi

I-Nickel ithuthukisa ukugayaukuzinza kwesendlalelo se-chromium oxide esenziwayoevikela insimbi engagqwali ekugqwaleni. Ukungabikho kwe-nickel emabangeni angu-400 ochungechunge kuyabenzaimelana kancane nokugqwalauma kuqhathaniswa nochungechunge lwama-300.

b) Ukungcoliswa komhlaba

Uma kuvezwe ku:

• I-chloride ions (isb, emanzini anosawoti noma usawoti we-deicing)

• Izinto ezingcolisa izimboni

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

c) Isondlo Esingalungile noma Ukuvezwa

Ezindaweni ezingaphandle ezinomswakama ophezulu, imvula ene-asidi, noma isifutho sikasawoti, insimbi engavikelekile engu-400 isengozini enkulu yokugqwala. Ngaphandle kokwelashwa okufanele kwendawo, ukubola nokugqwala kungenzeka ngokuhamba kwesikhathi.

3. Umehluko Phakathi Kwebanga Le-Ferritic ne-Martensitic

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

I-Ferritic (isb, 409, 430)

• Uzibuthe

• Ukumelana nokugqwala okumaphakathi

• Ilungele indawo yangaphakathi noma enokugqwala kancane

• Ukwakheka okungcono kanye nokushisela

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

• Yenza lukhuni ukwelashwa ngokushisa

• Okuqukethwe kwekhabhoni ephezulu

• Amandla aphezulu nokumelana nokugqoka

• Imelana nokugqwala kancane kune-ferritic ngaphandle uma ingadlulisiwe noma imboziwe

Ukuqonda ukuthi yisiphi isigaba esingaphansi osisebenzisayo kubalulekile ekulinganiseni ukusebenza kokugqwala.

4. Izicelo Zomhlaba Wangempela kanye Nokulindelekile Kokugqwala Kwazo

Iukukhetha 400 series gradekufanele ihambisane ne-ukuchayeka kwemvelo kohlelo lokusebenza:

• 409 Insimbi Engagqwali: Okuvame ukusetshenziswa kuma-exhausts ezimoto. Ingagqwala ngokuhamba kwesikhathi kodwa inikeza ukumelana nokugqwala okwamukelekayo ezindaweni ezinokushisa okuphezulu.

• 410 Insimbi Engagqwali: Isetshenziswa ku-cutlery, ama-valve, ama-fasteners. Ijwayele ukugqwala ngaphandle kokudlula phezulu.

• 430 Insimbi Engagqwali: Idume ngezinto zikagesi zasekhishini, osinki, namaphaneli okuhlobisa. Ukumelana nokugqwala okuhle kwangaphakathi, kodwa kungagqwala uma kusetshenziswe ngaphandle.

• 440 Insimbi Engagqwali: Ukuqina okuphezulu kwama-blades namathuluzi okuhlinza, kodwa kulula ukungena endaweni enomswakama uma kungaqediwe kahle.

At sakysteel, seluleka amakhasimende ngebanga elifaneleka kakhulu lochungechunge lwe-400 kuye ngokuchayeka kwemvelo kanye nokulindela ukugqwala.
