Intsimbi engatyiwayo ibhiyozelwa ngokuxhathisa kwayo ekumdleni, ukuqina, kunye nobuhle obunomtsalane. Nangona kunjalo, akuwona onke amabakala ensimbi engenasici anika inqanaba elifanayo lokukhusela kwi-rust. Omnye wemibuzo edla ngokubuzwa phakathi kweenjineli, abayili bezakhiwo, kunye nabavelisi yile:Ngaba 400 series steel stainless umhlwa?
Impendulo emfutshane yile:ewe, 400 series steel stainless can rusa, ngakumbi phantsi kweemeko ezithile zokusingqongileyo. Nangona isanikeza ukuxhathisa okungcono kwe-corrosion kune-carbon steel, ukusebenza kwayo kuxhomekeke kwibakala elithile, ukwakheka kunye nokusingqongileyo kwenkonzo. Kweli nqaku, siza kuntywila kwiukuxhathisa umhlwa of 400 series steel stainless, phonononga izinto eziphembelela ukusebenza kwayo, kwaye inike isikhokelo malunga nendawo kunye nendlela yokuyisebenzisa ngokufanelekileyo.
Njengomthengisi othembekileyo weemveliso zentsimbi engenasici,sakysteelIlapha ukuze ikuncede uqonde indlela yokwenza ukhetho olunolwazi xa ukhetha ibakala elifanelekileyo leprojekthi yakho.
1. Ukuqonda 400 Series Stainless Steel
I 400 series steels stainless lusaphoferritic kunye martensiticingxubevange yentsimbi. Ngokungafaniyo ne-austenitic 300 series (njenge-304 kunye ne-316), uluhlu lwe-400 ngokubanziiqulethe i-nickel encinci okanye ayikho, echaphazela kakhulu ukuxhathisa umhlwa.
Amanqaku aqhelekileyo angama-400 aquka:
-
409: Isetyenziswa kwiinkqubo zokukhupha iimoto
-
410: Ibakala le-martensitic lenjongo ngokubanzi
-
420: Yaziwa ngobulukhuni obuphezulu kunye nezicelo zokusika
-
430: Ukuhombisa kunye ne-corrosion-resistant kusetyenziso lwangaphakathi
-
440: Ikhabhoni ephezulu, ibakala elilukhuni elisetyenziselwa iiblade kunye nezixhobo
La mabanga aqulatheI-11% ukuya kwi-18% yechromium, eyenza umaleko weoxide we-passive onceda ukuxhathisa umhlwa. Nangona kunjalo, ngaphandle kwempembelelo yokukhusela ye-nickel (njengoko kubonwe kwi-series ye-300), olu luhlu luyiuzinzile kancinciphantsi kweemeko ezinobundlobongela.
2. Kutheni 400 Series Stainless Steel Rust?
Izinto ezininzi zinefuthe kwiutyekelo lokurusaye 400 series steel stainless:
a) Umxholo weNikeli ephantsi
I-nickel iphucula amandlauzinzo lomaleko wechromium oxide esenziwayoekhusela intsimbi engatyiwayo ekudlekeni. Ukungabikho kwe-nickel kumabakala angama-400 ochungechunge kubenzaiyakwazi ukumelana ne-corrosionxa kuthelekiswa 300 series.
b) Ungcoliseko loMphezulu
Ukuba iboniswe kwi:
-
I-chloride ion (umzekelo, emanzini anetyuwa okanye ityuwa ye-deicing)
-
Ungcoliseko lwemizi-mveliso
-
Ukucocwa okungafanelekanga okanye iintsalela zokwenziwa
umaleko okhuselayo wechromium oxide unokuphazamiseka, ubangeleukubola komngxuma or amabala omhlwa.
c) Isondlo esilambathayo okanye ukuVezwa
Kwiindawo zangaphandle ezinomswakama ophezulu, imvula ye-asidi, okanye isitshizi setyuwa, iintsimbi ezingakhuselekanga ze-400 zentsimbi zisengozini yokubola. Ngaphandle konyango olululo lomphezulu, amabala kunye nomhlwa kunokwenzeka ngokuhamba kwexesha.
3. Umahluko phakathi kweBanga leFerritic neMartensitic
Uluhlu lwe-400 lubandakanya zombinii-ferritickwayemartensiticiintsimbi ezingenasici, kwaye ziziphatha ngendlela eyahlukileyo ngokwemiqathango yokumelana nomhlwa.
Ferritic (umz., 409, 430)
-
Imagnethi
-
Ukumelana nomhlwa okuphakathi
-
Ilungele ngaphakathi okanye imeko-bume enomhlwa kancinci
-
Ubume obungcono kunye ne-weldability
Martensitic (umz., 410, 420, 440)
-
Ilukhuni ngonyango lobushushu
-
Umxholo wekhabhoni ophezulu
-
Amandla aphezulu kunye nokumelana nokugqoka
-
Ukumelana ne-corrosion encinci kune-ferritic ngaphandle kokuba idlulisiwe okanye igqunywe
Ukuqonda ukuba loluphi udidi olusezantsi olusebenzisayo kubalulekile ukuqikelela ukusebenza komhlwa.
4. Izicelo ze-Real-World kunye noLindelo lwazo lwe-Corrosion
Iukhetho 400 series gradekufuneka ihambelane neukuvezwa kokusingqongileyo kwesicelo:
-
409 Intsimbi engatyiwa: Isetyenziswa rhoqo kwi-exhausts zemoto. Iyakwazi ukugqwala ngokuhamba kwexesha kodwa inika ukuxhathisa okwamkelekileyo kokumhlwa kwindawo ezinobushushu obuphezulu.
-
410 intsimbi engatyiwa: Isetyenziswe kwi-cutlery, i-valve, i-fasteners. Ithambekele ekudlekeni ngaphandle kokudlula kumphezulu.
-
430 iNtsimbi eNgatyiwayo: Idumile kwizixhobo zasekhitshini, iisinki, kunye neepaneli zokuhombisa. Ukumelana nokuthotywa kakuhle kwangaphakathi, kodwa kunokugqwala ukuba isetyenziswe ngaphandle.
-
440 Intsimbi engatyiwa: Ukuqina okuphezulu kweencakuba kunye nezixhobo zotyando, kodwa kulula ukugqobhoza kwindawo efumileyo ukuba ayigqitywanga kakuhle.
At sakysteel, sicebisa abathengi ngeyona bakala ifanelekileyo ye-400 yochungechunge ngokuxhomekeke ekuvezweni kwabo kokusingqongileyo kunye nokulindela ukubola.
5. Ukuthelekisa 400 Series kunye 300 Series Stainless Steel
| Ipropati | 300 Series (umz., 304, 316) | 400 Series (umz., 410, 430) |
|---|---|---|
| Umxholo weNickel | 8–10% | Ubuncinci ukuya nakwenye |
| Ukunyangwa kokuMhlwa | Phezulu | Phakathi ukuya phantsi |
| Imagnethi | Ngokuqhelekileyo ayinamagnetic | Imagnethi |
| Ukuba lukhuni | Ayinakuqiniswa | Iyaqina (martensitic) |
| Iindleko | Phezulu | Ngasezantsi |
Urhwebo-off yokonga iindleko kunye 400 series naukunciphisa ukuxhathisa umhlwa. Kubangaphakathi, iindawo ezomileyo, inokwanela. Kodwa ngenxaiimeko zaselwandle, zekhemikhali, okanye ezimanzi, Uchungechunge lwe-300 lufanelekile ngakumbi.
6. Ukuthintela umhlwa kwi-400 Series ye-Stainless Steel
Ngelixa uthotho lwe-400 yentsimbi engatyiwayo inokugqwala, kukho ezininziamanyathelo okuthintelaukomeleza ukuxhathisa kwayo kukutya:
a) Ukugqitywa komphezulu
Ukucwenga, ukunyanzeliswa, okanye ukugquma (njengokugquma umgubo okanye i-electroplating) kunokunciphisa kakhulu umngcipheko wokugqwala.
b) Ukucoca kunye noLondolozo
Ukucoca rhoqo ukususa ukungcola okufana netyuwa, ubumdaka, kunye nezingcolisi zamashishini kunceda ukugcina umphezulu.
c) Ugcino olululo
Gcina imathiriyeli kwindawo eyomileyo, egqunyiweyo ukunciphisa ukufuma kunye nokuvela kokufuma phambi kokusetyenziswa.
d) Ukusetyenziswa kweeNqaku zoKhuseleko
Iingubo ze-epoxy okanye i-polyurethane zinokukhusela umphezulu wentsimbi kwindawo ezonakalisayo.
sakysteelibonelela ngeenkonzo ezongeziweyo zexabiso ezifana nokugulisa kunye nokwaleka ukwandisa ubomi bakho 400 uthotho iimveliso zentsimbi.
7. Ngaba kufuneka Uphephe 400 Series Steel?
Akunjalo. Nangona kunjaloukuxhathisa umhlwa okuphantsi, 400 series steel stainless ibonelela ngeenzuzo ezininzi:
-
Iindleko eziphantsingaphezu 300 series
-
Ukumelana nokunxiba kakuhlekunye nobunzima (amanqaku e-martensitic)
-
Imagnethikwizicelo ezithile zoshishino
-
Ukumelana nomhlwa okwaneleyokwindawo engaphakathi, eyomileyo, okanye enomhlwa kancinci
Ukukhetha ibakala elililo kuxhomekeke kulwakhouhlahlo lwabiwo-mali, ukusetyenziswa, kunye neemeko zokuvezwa.
