Ngaba i-400 Series Stainless Steel Rust?

Intsimbi engagqwaliyo idume ngokumelana kwayo nokugqwala, ukuqina kwayo, kunye nokuthandeka kwayo. Nangona kunjalo, ayizizo zonke iintlobo zentsimbi engagqwaliyo ezibonelela ngenqanaba elifanayo lokhuseleko kumhlwa. Omnye wemibuzo ebuzwa rhoqo phakathi kweenjineli, abakhi bezakhiwo, kunye nabavelisi ngulo:Ngaba intsimbi engagqwaliyo ye-400 series iyagqwala?

Impendulo emfutshane yile:ewe, intsimbi engagqwaliyo engama-400 yothotho inokugqwala, ingakumbi phantsi kweemeko ezithile zokusingqongileyo. Nangona isabonelela ngokumelana nokugqwala okungcono kunentsimbi yekhabhoni, ukusebenza kwayo kuxhomekeke kudidi oluthile, ukwakheka, kunye nendawo yenkonzo. Kweli nqaku, siza kungena kwiukumelana nokugqwala kwentsimbi engagqwali yochungechunge lwe-400, jonga izinto ezichaphazela ukusebenza kwayo, kwaye unike isikhokelo sokuba ingasetyenziswa phi kwaye njani ngokufanelekileyo.

Njengomthengisi othembekileyo weemveliso zentsimbi engagqwaliyo,i-sakysteelilapha ukukunceda uqonde indlela yokwenza ukhetho olunolwazi xa ukhetha ibakala elifanelekileyo leprojekthi yakho.

1. Ukuqonda i-400 Series Stainless Steel

Iintsimbi ezingenasici ezingama-400 ziyinxalenye yosaphoi-ferritic kunye ne-martensiticii-alloys zentsimbi engagqwaliyo. Ngokungafaniyo nothotho lwe-austenitic 300 (njenge-304 kunye ne-316), uthotho lwe-400 ngokubanziine-nickel encinci okanye ayikho, nto leyo echaphazela kakhulu ukumelana nokugqwala.

Amanqaku aqhelekileyo ochungechunge lwama-400 aquka:

• 409: Isetyenziswa kwiinkqubo zokukhupha umoya kwiimoto

• 410: Ibanga le-martensitic elisetyenziselwa iinjongo ngokubanzi

• 420: Yaziwa ngokuqina okuphezulu kunye nokusetyenziswa kwezitya

• 430: Ilungele ukusetyenziswa ngaphakathi endlwini kwaye ayimelani nokugqwala

• 440: I-carbon ephezulu, uhlobo oluqiniswayo olusetyenziswa kwiiblade nezixhobo

Ezi klasi zihlala ziqulatheI-11% ukuya kwi-18% ye-chromium, eyenza umaleko we-oxide ongasebenziyo onceda ekumelaneni nomhlwa. Nangona kunjalo, ngaphandle kwempembelelo yokukhusela ye-nickel (njengoko kubonwe kuthotho lwe-300), lo maleko uyasebenzaukungazinzi kakuhlephantsi kweemeko ezinzima.

2. Kutheni i-400 Series Stainless Steel Rust inokuba ne-400 Series?

Ziliqela izinto ezichaphazelautyekelo lokugqwalayentsimbi engagqwaliyo yochungechunge lwe-400:

a) Umxholo ophantsi weNickel

I-Nickel iyayiphuculauzinzo lomaleko we-chromium oxide ongasebenziyoekhusela intsimbi engagqwaliyo ekuboleni. Ukungabikho kwe-nickel kwiigreyidi ezingama-400 kuyenza ibeayixhathisi kakhulu ukugqwalaxa kuthelekiswa nothotho lwama-300.

b) Ungcoliseko lomphezulu

Ukuba utyhileke ku:

• Ii-ion ze-chloride (umz., ezivela kumanzi anetyuwa okanye kwiityuwa zokucoca)

• Ungcoliseko lwemizi-mveliso

• Ukucoca okungafanelekanga okanye iintsalela zokwenza izinto
  umaleko we-chromium oxide okhuselayo unokuphazamiseka, okubangelaukugqwala kwemingxuma or amabala okugqwala.

c) Ukugcinwa Kakubi okanye Ukuvezwa Kakubi

Kwiindawo zangaphandle ezinomswakama ophezulu, imvula ene-asidi, okanye i-spray yetyuwa, intsimbi engakhuselekanga ye-400 series isengozini enkulu yokugqwala. Ngaphandle konyango olufanelekileyo lomphezulu, ukudaya kunye nokugqwala kunokwenzeka ngokuhamba kwexesha.

3. Umahluko phakathi kwamanqanaba e-Ferritic kunye ne-Martensitic

Olu luhlu lwama-400 luquka zombinii-ferritickwayei-martensiticiintsimbi ezingenasici, kwaye ziziphatha ngendlela eyahlukileyo ngokubhekiselele ekumelaneni nokugqwala.

I-Ferritic (umz., 409, 430)

• Imagnethi

• Ukumelana nokugqwala okuphakathi

• Ilungele iindawo ezingaphakathi okanye ezingcolisa kancinci

• Ukwakheka ngcono kunye nokudityaniswa

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

• Iyaqina ngonyango lobushushu

• Umxholo ophezulu wekhabhoni

• Amandla aphezulu kunye nokumelana nokuguguleka

• Ayikwazi ukumelana nokugqwala kakhulu kune-ferritic ngaphandle kokuba ayifakwanga okanye igqunywe nge-camera

Ukuqonda ukuba loluphi uhlobo lweklasi olusebenzisayo kubalulekile ekuqikeleleni ukusebenza kwe-rust.

4. Izicelo zeHlabathi lokwenyani kunye nolindelo lwazo lokugqwala

Iukhetho lwebanga lothotho lwama-400kufuneka ihambelane neukuvezwa kokusingqongileyo kwesicelo:

• 409 Intsimbi Engagqwaliyo: Isetyenziswa rhoqo kwiimoto ezikhupha umoya. Ingagqwala ngokuhamba kwexesha kodwa inika ukumelana nokugqwala okwamkelekileyo kwiindawo ezishushu kakhulu.

• 410 Intsimbi Engagqwaliyo: Isetyenziswa kwizinto zokusika, iivalvu, izibophelelo. Inokugqwala ngaphandle kokuphazamiseka komphezulu.

• Intsimbi Engagqwaliyo engama-430: Ithandwa kakhulu kwizixhobo zasekhitshini, kwiisinki, nakwiiphaneli zokuhombisa. Iyakwazi ukumelana nokugqwala ngaphakathi, kodwa isenokugqwala ukuba isetyenziswa ngaphandle.

• Intsimbi Engagqwaliyo engama-440: Ubunzima obuphezulu kwiiblade nezixhobo zotyando, kodwa kulula ukubamba imingxuma kwiindawo ezimanzi ukuba azigqitywanga kakuhle.

At i-sakysteel, sicebisa abathengi ngebanga elifanelekileyo le-400 series ngokuxhomekeke kumngcipheko wabo wokungcola kwendalo kunye nolindelo lokugqwala.
