Kodi 316L Stainless Steel Ili ndi Nickel?

Chitsulo chosapanga dzimbiri cha 316L ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri komanso zosunthika m'mafakitale zomwe zimafunikira kukana kwa dzimbiri, kulimba, komanso ukhondo. Monga kusiyana kwa mpweya wochepa wa 316 zitsulo zosapanga dzimbiri, 316L imayamikiridwa kwambiri muzogwiritsira ntchito kuyambira pakupanga mankhwala ndi malo apanyanja mpaka kupanga zakudya ndi zipangizo zamankhwala. Funso lomwe limafunsidwa ndi mainjiniya, opanga, komanso ogula osamala zachilengedwe ndi:Kodi 316L chitsulo chosapanga dzimbiri chili ndi faifi tambala?

Yankho ndiloinde- 316L chitsulo chosapanga dzimbiriimakhala ndi nickelmonga chimodzi mwa zinthu zake zoyamba za alloying. M'malo mwake, nickel ndiwothandizira kwambiri pazinthu zambiri zofunika za 316L. M'nkhaniyi, tikambirana zanickel zili mkati316L chitsulo chosapanga dzimbiri, gawo lake pamapangidwe a aloyi, ndi chifukwa chake izi zimafunikira pakugwira ntchito, kukana dzimbiri, kuyanjana kwachilengedwe, ndi mtengo.

Monga ogulitsa zitsulo zosapanga dzimbiri,sakysteelyadzipereka kupereka mayankho azinthu zowonekera bwino komanso kuzindikira kwaukadaulo. Tiyeni tiwone bwino za 316L chitsulo chosapanga dzimbiri komanso gawo la nickel pakuchita kwake.

1. Chemical Composition of 316L Stainless Steel

316L chitsulo chosapanga dzimbiri ndi gawo labanja la austeniticzazitsulo zosapanga dzimbiri, zomwe zimatanthauzidwa ndi mawonekedwe awo amtundu wa cubic (FCC) wokhazikika ndinickel.

Zomwe zimapangidwa ndi mankhwala a 316L ndi:

  • Chromium (Cr)16.0 - 18.0%

  • Nickel (Ndi): 10.0 - 14.0%

  • Molybdenum (Mo)2.0 - 3.0%

  • Mpweya (C)≤ 0.03%

  • Manganese (Mn)≤ 2.0%

  • Silicon (Si)≤ 1.0%

  • Chitsulo (Fe): Kusamala

Thenickel zili 316L nthawi zambiri zimakhala pakati pa 10 ndi 14 peresenti, kutengera kapangidwe kake ndi miyezo yomwe ikutsatiridwa (ASTM, EN, JIS, etc.).

2. Chifukwa Chiyani Nickel Amawonjezedwa ku 316L Stainless Steel?

Nickel amasewera angapomaudindo ofunikiramumayendedwe amankhwala ndi makina a 316L:

a) Kukhazikika kwa Austenitic Structure

Nickel imathandizira kukhazikikaaustenitic gawoyachitsulo chosapanga dzimbiri, chomwe chimapangitsa kuti chiwoneke bwino, chokhazikika komanso cholimba. Zitsulo zosapanga dzimbiri za Austenitic ngati 316L zimakhalabe zopanda maginito ndipo zimakhalabe ndi mphamvu ngakhale kutentha kwa cryogenic.

b) Kulimbana ndi Corrosion Resistance

Nickel, kuphatikiza chromium ndi molybdenum, imayenda bwino kwambirikukana dzimbiri, makamaka m'malo okhala ndi chloride monga:

  • Madzi a m'nyanja

  • Matanki amankhwala

  • Zida zopangira chakudya

  • Zida zopangira opaleshoni ndi mano

c) Kupititsa patsogolo Weldability

Nickel amathandizirakuchepetsa chiwopsezo cha kuswekam'malo olumikizirana, kulola 316L kuti igwiritsidwe ntchito mozama muzinthu zowotcherera ndi mapaipi opanda chithandizo cha kutentha pambuyo pa weld.

d) Mphamvu zamakina ndi Ductility

Nickel imawonjezera mphamvuzokolola ndi kulimba mphamvualoyi popanda kusokoneza kusinthasintha kwake, kupanga 316L kukhala yabwino kwa zotengera zokakamiza, machubu osinthika, ndi zigawo zina zonyamula katundu.

3. Kusiyana Pakati pa 304 ndi 316L mu Migwirizano ya Nickel Content

Wina omwe amagwiritsidwa ntchito kwambiri ndi chitsulo chosapanga dzimbiri304, yomwe ilinso ndi faifi tambala koma mulibe molybdenum. Kusiyana kwakukulu ndi:

Katundu 304 Chitsulo chosapanga dzimbiri 316L Chitsulo chosapanga dzimbiri
Zinthu za Nickel 8 - 10.5% 10 - 14%
Molybdenum Palibe 2 - 3%
Kukaniza kwa Corrosion Zabwino Zokwanira, makamaka mu ma chloride

Chifukwa chakekuchuluka kwa nickel ndi molybdenum, 316L imapereka kukana kwa dzimbiri kowonjezereka poyerekeza ndi 304.

4. Ndi 316L Stainless Steel Magnetic?

316L chitsulo chosapanga dzimbiri ndiwopanda maginitom'malo mwake, chifukwa cha mawonekedwe ake austenitic okhazikika ndi faifi tambala. Izi zimapangitsa kuti zikhale zoyenera:

  • Zida zamankhwala zogwirizana ndi MRI

  • Electronics nyumba

  • Mapulogalamu omwe kusokoneza maginito kuyenera kupewedwa

Komabe, kugwira ntchito kozizira kapena kuwotcherera kungayambitse maginito pang'ono chifukwa cha kusintha kwa martensitic, koma zoyambira zimakhalabe zopanda maginito.

5. Ntchito za 316L Stainless Steel

Chifukwa cha kukhalapo kwa faifi tambala ndi zinthu zina zophatikizika, 316L imachita bwino mu:

  • Zida zam'madzi: zitsulo zopangira ma propeller, zopangira maboti, ndi anangula

  • Chemical processing: akasinja, mapaipi, mavavu owonetsedwa ndi zinthu zaukali

  • Zida zamankhwala: implants, zida zopangira opaleshoni, zida za orthodontic

  • Chakudya ndi zakumwa: akasinja okonza, malamba onyamula katundu, makina oyeretsera malo

  • Mafuta ndi gasi: nsanja za m'mphepete mwa nyanja, makina a mapaipi

  • Zomangamanga: njanji za m'mphepete mwa nyanja, makoma a nsalu

At sakysteel, timapereka 316L zitsulo zosapanga dzimbiri m'njira zosiyanasiyana - kuphatikizapo mbale, pepala, chitoliro, chubu, ndodo, ndi zopangira - zonse zovomerezeka kuti zigwirizane ndi miyezo yapadziko lonse monga ASTM A240, A312, ndi EN 1.4404.

6. Kodi Nickel Ndi Nkhawa Yaumoyo mu 316L Stainless Steel?

Kwa ogwiritsa ntchito ambiri ndi mapulogalamu,nickel mu 316L chitsulo chosapanga dzimbiri sichowopsa paumoyo. Aloyiyo ndi yokhazikika, ndipo faifiyo imamangidwa mkati mwazitsulo zachitsulo, kutanthauza kuti sizitsika pansi pazigwiritsidwe ntchito bwino.

M'malo mwake, 316L imagwiritsidwa ntchito kwambiri mu:

  • Ma implants opangira opaleshoni

  • Zida zamano

  • Hypodermic singano

Zakebiocompatibilitykomanso kukana dzimbiri kumapangitsa kuti ikhale imodzi mwazinthu zotetezeka kwambiri kukhudzana ndi anthu. Komabe, anthu omwe ali ndi vuto lalikulu la nickel angafunikebe kusamala akavala zodzikongoletsera zachitsulo chosapanga dzimbiri kapena implants zachipatala.

7. Zotsatira za Mtengo wa Nickel mu 316L

Nickel ndi chinthu chokwera mtengo kwambiri cha alloying, ndipo mtengo wake wamsika ukhoza kusinthasintha potengera zomwe dziko likufuna komanso kupezeka. Zotsatira zake:

  • 316L chitsulo chosapanga dzimbiri nthawi zambiriokwera mtengokuposa 304 kapena masukulu a ferritic

  • Mtengo wokwera umachepetsedwa ndintchito zapamwamba, makamaka m'malo ovuta

At sakysteel, timapereka mitengo yampikisano pazipangizo za 316L potengera maubale olimba a unyolo komanso kuchuluka kwa kupanga.

8. Momwe Mungatsimikizire Zinthu za Nickel mu 316L

Kutsimikizira kupezeka kwa nickel mu 316L chitsulo chosapanga dzimbiri, njira zoyesera zakuthupi zikuphatikiza:

  • X-ray fluorescence (XRF): Zofulumira komanso zosawononga

  • Optical Emission Spectroscopy (OES): Kusanthula kwatsatanetsatane kwapangidwe

  • Ziphaso Zoyeserera za Mill (MTCs): Zoperekedwa ndi aliyensesakysteelkutumiza kutsimikizira kutsatiridwa ndi zofunikira za mankhwala

Nthawi zonse pemphani satifiketi yowunikira ngati zinthu za nickel zenizeni ndizofunikira pakugwiritsa ntchito kwanu.

Mapeto

Choncho,Kodi 316L chitsulo chosapanga dzimbiri chili ndi faifi tambala?Mwamtheradi. Pamenepo,faifi tambala ndizofunikira pamapangidwe ake ndi magwiridwe ake. Ndi 10-14% ya faifi tambala, 316L imapereka kukana kwa dzimbiri, mphamvu, ndi mawonekedwe - kupangitsa kuti ikhale yabwino kwa mafakitale monga apanyanja, azachipatala, mankhwala, ndi kukonza zakudya.

Ngakhale faifi amathandizira pamtengo wazinthu, zimatsimikiziranso kudalirika kwanthawi yayitali komanso kuchita bwino kwambiri m'malo ankhanza. Ngati ntchito yanu ikufuna aloyi yogwira ntchito kwambiri yokhala ndi zotsatira zotsimikizika, 316L ndi chisankho chabwino kwambiri.
