Incamake ya Duplex idafite ibyuma

Super Duplex idafite ibyuma itandukanijwe nitsinda risanzwe duplex ku buryo bwayo byateje imbere ibintu bya kashe. Nibikoresho bifatika cyane hamwe nibikorwa byo hejuru byibintu byo kurwanya ruswa nka chromium (Cr) na molybdenum (mo). Icyiciro cyambere cya Super Duplex Groel Stain, S32750, igizwe na 28.0% ya chromium, 3,5% molybdenum, na nikel ya 8.0% (ni). Ibi bice bitanga kurwanya bidasanzwe abashinzwe rubyaro, harimo aside, chloride, nibisubizo bya caustic.

Mubisanzwe, super duplex idafite ibyuma bidasubirwaho ku nyungu zashyizweho za duplex amanota hamwe no kuzamura imiti yongerewe imiti. Ibi bituma habaho amanota meza yo guhimba ibice byingenzi murwego rwa peterolochemical, nko guhanahana ubushyuhe, boiart, nibikoresho byo guhatirwa.

Ibyiciro bya duplex idafite ibyuma

Ubwoko bwambere ni ubwoko bwa alloy buke, hamwe nicyiciro gihagarariwe cya S32304 (23CR-4NI-0.1n). Ibyuma ntabwo birimo Molybdenum, kandi agaciro ka mbere ni 24-25. Irashobora gukoreshwa aho gukoreshwa muri Aisi304 cyangwa 316 muguhangayikishwa no kurwanya ruswa.

Ubwoko bwa kabiri bufite ubwoko bwo hagati, ikirango gihagarariye ntabwo kiri s31803 (22cr-3Mi-3MO-Agaciro kayo kari hagati ya Ai 156L na 6% Icyuma kitagira ingano.

Ubwoko bwa gatatu bwubwoko bwa alloy, muri rusange burimo 25% cr, Molybdenum na azote, ndetse nabyo birimo kandi umuringa na tungsten. Icyiciro gisanzwe UNSS32550 (25CR-3Ni-3Mo-2CU-2CI-0.2N), Agaciro kambere ni 38-39, kandi irwanya ruswa ni 30 cr duplex idafite ibyuma.

l Ubwoko bwa kane ni super duplex idafite ibyuma, birimo molybdenum ya morebdenum na azote. Icyiciro gisanzwe ntabwo kiri munsi ya S32750 (25CR-7Ni-3.7Mo-0.3N), ndetse nazo zirimo nongsten n'umuringa. Agaciro kambere karenze 40, kashobora gukoreshwa mubice bikaze. Ifite ihohoterwa rishingiye ku nyakaro n'imitungo yuzuye, ishobora kugereranywa na super austentique ibyuma.

Inyungu za Duplex idafite ibyuma

Nkuko byavuzwe haruguru, duplex mubisanzwe ikora neza kuruta ubwoko bwicyuma iboneka mubukonje bwayo. Nibyiza, guhuza ibiranga ibyiza biva mubintu bya austeteite na Ferrite bitanga igisubizo cyiza muri rusange kubibazo byinshi byumusaruro.

l Kurwanya imiterere - ingaruka za Molybdenum, Chromium, na azote kumavuta yo kurwanya ruprosion ya duplex Alloys ni nyinshi. Ibikoresho byinshi bya duplex birashobora guhuza no kurenga ku kurwanya ruswa mu manota azwi cyane harimo 304 na 316. Bagirira akamaro cyane inzitisi no gukubita ruswa.

l Stress CORROSIKIN CROSRSION - SSC iza nkigisubizo cyibintu byinshi byikirere - ubushyuhe nubushuhe bizaba aribyo bigaragara cyane. Imihangayiko minini yongeraho gusa nikibazo. Amanota asanzwe aSustenic yongeye kwibasirwa cyane no guhangayikishwa na kanseri - duplex ibyuma bidafite ingaruka ntabwo.

l Gutongana - duplex irakomeye kuruta amababi ya Ferritic - ndetse no ku bushyuhe bwo hasi mugihe bidahuye nibikorwa byimikorere ya ASITETIIT muriyi ngingo.

L Imbaraga - Duplex Alloys irashobora kuba hakomeye inshuro 2 kurenza inzego za ausenitike ninkunga. Imbaraga zo hejuru zisobanura ko ibyuma gikomeje kuba hamwe nubunini bwingenzi cyane cyane mugugabanya urwego rwibiremere.
