Ngaba iStainless Steel inokunyangwa ngobushushu?

Intsimbi engatyiwa yenye yezona zinto zisetyenziswa kakhulu ehlabathini, eyaziwa ngokuxhathisa ukubola, ukomelela, kunye nenkangeleko ecocekileyo. Kodwa umbuzo oqhelekileyo odla ngokubuzwa kuzo zombini iiseyile zeshishini kunye nobunjineli yile:Ingaba intsimbi engatyiwayo inokunyangwa bubushushu?Impendulo ngu-ewe-kodwa kuxhomekeke kuhlobo lwensimbi engenasici kunye neziphumo ezifunwayo.

Kweli nqaku, siphonononga ukuba zeziphi iintsimbi ezingenasici ezinokunyangwa ubushushu, iindlela ezahlukeneyo zonyango lobushushu, kunye nendlela oku kuchaphazela ngayo ukusebenza kwizicelo zehlabathi zangempela.

Ukuqonda Iintlobo zeStainless Steel

Ukuqonda amathuba onyango lobushushu, kubalulekile ukwazi ezona ndidi ziphambili zentsimbi engenasici:

1. Intsimbi yeAustenitic engatyiwa(umz., 304, 316)
   La ngawona mabanga aqhelekileyo, aziwa ngokugqwesa ukuxhathisa umhlwa kodwaayinako ukuqina ngonyango lobushushu. Zinokuqiniswa kuphela ngokusebenza okubandayo.

2. Intsimbi yentsimbi yeMartensitic(umz., 410, 420, 440C)
   La mabangainokunyangwa ubushushuukufezekisa ubunzima obuphezulu kunye namandla, afana ne-carbon steels.

3. Intsimbi yentsimbi yeFerritic(umz., 430)
   Iintlobo zeFerritic zinobunzima obulinganiselweyo kunyeayinako ukuqina kakhulu ngonyango lobushushu. Zihlala zisetyenziswa kwi-auto trim kunye nezixhobo zombane.

4. Duplex Steel engatyiwa(umz., 2205, S31803)
   Ezi ntsimbi zine-microstructure edibeneyo ye-austenite kunye ne-ferrite. Ngoxa bonainokungena isisombululo, baziayilungelanga ukuqinangeendlela zonyango ubushushu bemveli.

5. Imvula Ukwenza lukhuni intsimbi engatyiwayo(umz., 17-4PH / 630)
   Ezi zinokuphathwa ubushushu ukuya kumanqanaba amandla aphezulu kakhulu kwaye ziqhele ukusetyenziswa kwi-aerospace kunye nezicelo zesakhiwo ezinomthwalo ophezulu.

At sakysteel, sinikezela zonke iindidi ezinkulu zensimbi engenasici, kubandakanywa i-martensitic ephathwa ukushisa kunye nemvula enzima amabakala kunye nesiqinisekiso esipheleleyo sezinto eziphathekayo kunye nokulandeleka.

Iindlela zoNyango loBubushushu kwiNtsimbi eNgatyiwayo

Inkqubo yokushisa ukushisa kwensimbi engenasici ibandakanya ukufudumeza okulawulwayo kunye nokupholisa imijikelezo yokuguqula i-microstructure kunye neempawu zomatshini. Apha ngezantsi zezona nkqubo zixhaphakileyo zonyango lobushushu ezisetyenziswa kwiintsimbi ezahlukeneyo ezingenastainless:

1. Ukucoca

Injongo:Ikhulula uxinzelelo lwangaphakathi, ithambisa intsimbi, kwaye iphucula i-ductility.
Amabanga afanelekileyo:I-Austenitic, i-ferritic, i-duplex iintsimbi ezingenasici.

I-Anealing ibandakanya ukufudumeza intsimbi kwiqondo lokushisa kwe-1900-2100 ° F (1040-1150 ° C) kwaye emva koko ipholise ngokukhawuleza, ngokuqhelekileyo emanzini okanye emoyeni. Oku kubuyisela ukuxhathisa kwe-corrosion kwaye kwenza izinto zibe lula ukwenza okanye umatshini.

2. Ukuqina

Injongo:Yandisa amandla kunye nokumelana nokunxiba.
Amabanga afanelekileyo:Iintsimbi zeMartensitic ezingenasici.

Ukuqina kufuna ukufudumeza izinto kwiqondo lokushisa eliphezulu (malunga ne-1000-1100 ° C), kulandelwa ukucima ngokukhawuleza kwioli okanye emoyeni. Oku kukhokelela kwisakhiwo esiqinileyo kodwa esine-brittle, esihlala silandelwa kukufudumala ukulungisa ukuqina kunye nokuqina.

3. Ukufudumeza

Injongo:Yehlisa ubuqhophololo emva kokuqina.
Amabanga afanelekileyo:Iintsimbi zeMartensitic ezingenasici.

Emva kokuqina, ukufudumala kwenziwa ngokufudumeza intsimbi kwiqondo lokushisa eliphantsi (150-370 ° C), elinciphisa ukuqina kancinci kodwa liphucula ukuqina kunye nokusetyenziswa.

4. Ukuqina kwemvula (Ukuguga)

Injongo:Ukufumana amandla aphezulu kunye nokuchasana kokugqwala okulungileyo.
Amabanga afanelekileyo:Iintsimbi ze-PH ezingenasici (umzekelo, i-17-4PH).

Le nkqubo ibandakanya unyango lwesisombululo olulandelwa kukuguga kumaqondo aphantsi (480-620 ° C). Ivumela iinxalenye ukuba zifikelele kumanqanaba amandla aphezulu kakhulu kunye nokuphazamiseka okuncinci.

Kutheni Ubushushu buNyanga intsimbi engatyiwayo?

Kukho izizathu ezininzi zokuba kutheni abavelisi kunye neenjineli zikhethe unyango lobushushu kwintsimbi engenasici:

• Ukwandiswa Ukuqinaizixhobo zokusika, iincakuba, kunye namalungu angagugiyo

• Amandla Aphuculweyokumacandelo ezakhiwo kwi-aerospace kunye ne-automotive

• Ukuphelisa Uxinzeleloemva kwe-welding okanye ukusebenza okubandayo

• Ukuphuculwa kweMicrostructureukubuyisela ukuxhathisa ukubola kunye nokuphucula ukumila

Ukushisa ukunyanga ibakala elifanelekileyo lensimbi engenasici kuvumela ukuguquguquka ngakumbi kuyilo kunye nesicelo ngaphandle kokuncama ukhuseleko lwe-corrosion.

Imicelimngeni yoBubushushu bokuNyanga iNtsimbi eNgatyiwayo

Ngelixa kuluncedo, unyango lobushushu lwentsimbi engenastainless kufuneka ilawulwe ngononophelo:

• Ukutshisa ngokugqithisileyokunokukhokelela ekukhuleni kweenkozo kunye nokuncipha kokuqina

• Imvula yeCarbideinokunciphisa ukuxhathisa ukubola kwiintsimbi ze-austenitic ukuba ayipholiswanga kakuhle

• Ukugqwethwa kunye nokulwakungenzeka ukuba ukupholisa akufani

• Umphezulu oxidation kunye nokukalainokufuna ukuchongwa okanye ukunyangwa emva konyango

Yiyo loo nto kubalulekile ukusebenza kunye nababoneleli ngezinto eziphathekayo kunye neengcali zonyango lobushushu. Ngesakysteel, sinikezela ngezinto zombini eziluhlaza kunye nenkxaso yobugcisa ukuqinisekisa ukusetyenzwa kakuhle.

Izicelo eziFuna iNtsimbi eNyanga ngobushushu

Iintsimbi eziphathwa ngobushushu zisetyenziswa kakhulu apha:

• Iibhleyidi ze-injini kunye namacandelo e-injini

• Izixhobo zotyando kunye nokufakelwa kwezonyango

• Iibheringi kunye neeshafts

• Iivalvu, iimpompo, kunye nezixhobo zoxinzelelo

• Iifasteners eziphezulu kunye nemithombo

Nokuba ufuna ukuxhathisa umhlwa, ukomelela, okanye ukuxhathisa ukunxitywa, ukukhetha ibakala elifanelekileyo lentsimbi ephathwayo ngobushushu ngundoqo ekusebenzeni okuhlala ixesha elide.

Ukuqukumbela

Ewe, intsimbi engenasiciunakobaphathwe ubushushu-kuxhomekeke kwibakala kunye nesiphumo oyifunayo. Ngelixa amabakala e-austenitic kunye ne-ferritic awaqiniswanga ngonyango lobushushu, iintlobo zokuqina kwe-martensitic kunye nemvula zinokunyangwa ubushushu ukufezekisa amandla aphezulu kunye nobunzima.

Xa ukhetha intsimbi engatyiwayo kwisicelo sakho, kubalulekile ukuba ungaqwalaseli kuphela ukuxhathisa umhlwa kodwa nokuba unyango lobushushu luyafuneka na ekusebenzeni.

sakysteelinikeza ukhetho olubanzi lwamabakala ensimbi engenasici, kubandakanywa iinketho zokunyangwa kobushushu, kwaye inikezela ngesikhokelo seengcali zokukunceda ukhethe esona sisombululo silungileyo kwiprojekthi yakho. Qhagamshelana nathi ukuze ufunde ngakumbi malunga nobuchule bethu bezinto eziphathekayo kunye nenkxaso.
