Incamake y'ibyuma
Ibyuma: Ubwoko bwibyuma bizwiho kurwanya ruswa hamwe nibintu bidafite ingese, birimo byibura chromium 10.5% na karuboni ntarengwa ya 1.2%.
Ibyuma bitagira umwanda ni ibikoresho bikoreshwa cyane mu nganda zinyuranye, bizwiho kurwanya ruswa no guhuza byinshi. Mu byiciro byinshi by'ibyuma bitagira umwanda, 304, 304H, 304L, na 316 ni byo bikunze kugaragara, nk'uko bigaragara mu gipimo cya ASTM A240 / A240M kuri “Chromium na Chromium-Nickel Icyuma kitagira ibyuma, urupapuro, na Strip for Vessels Vessels and General Gusaba. ”
Ibi byiciro bine biri mubyiciro bimwe byibyuma. Bashobora gushyirwa mubyuma nka austenitis ibyuma bidafite ibyuma ukurikije imiterere yabyo kandi nkibice 300 bya chromium-nikel ibyuma bitagira umwanda ukurikije ibihimbano byabo. Itandukaniro ryibanze muri bo riri mubigize imiti, kurwanya ruswa, kurwanya ubushyuhe, hamwe nimirima ikoreshwa.
Icyuma cya Austenitike: Byibanze bigizwe nububiko bushingiye kububiko bwa kirisiti (γ icyiciro), butari magnetique, kandi bigashimangirwa cyane cyane no gukora ubukonje (bushobora gutera magnetisme). (GB / T 20878)
Ibigize imiti no kugereranya imikorere (Bishingiye ku bipimo bya ASTM)
304 Icyuma:
- Ibice nyamukuru: Harimo chromium hafi 17.5-19.5% na nikel 8-10.5%, hamwe na karubone nkeya (munsi ya 0.07%).
- Ibikoresho bya mashini: Yerekana imbaraga nziza (515 MPa) no kuramba (hafi 40% cyangwa irenga).
304L Icyuma:
- Ibice nyamukuru: Bisa na 304 ariko hamwe na karubone yagabanutse (munsi ya 0.03%).
- Ibikoresho bya mashini: Bitewe na karubone yo hasi, imbaraga zingana ziri munsi ya 304 (485 MPa), hamwe no kuramba. Ibiri munsi ya karubone byongera imikorere yo gusudira.
304H Icyuma:
- Ibice nyamukuru: Ibirimo karubone mubisanzwe biva kuri 0.04% kugeza 0.1%, hamwe na manganese yagabanutse (kumanuka kugeza 0.8%) hamwe na silikoni yiyongera (kugeza 1.0-2.0%). Chromium hamwe na nikel birasa na 304.
- Ibikoresho bya mashini: Imbaraga zingana (515 MPa) no kurambura ni kimwe na 304. Ifite imbaraga nubukomezi mubushyuhe bwinshi, bigatuma ibera ahantu hafite ubushyuhe bwinshi.
316 Icyuma:
- Ibice nyamukuru: Harimo chromium 16-18%, nikel 10-14%, na molybdenum 2-3%, hamwe na karubone iri munsi ya 0.08%.
- Ibikoresho bya mashini: Imbaraga zingana (515 MPa) no kuramba (kurenza 40%). Ifite imbaraga zo kurwanya ruswa.
Uhereye kubigereranya hejuru, biragaragara ko amanota ane afite imiterere yubukanishi. Itandukaniro riri mubigize, biganisha ku guhinduka muburyo bwo kurwanya ruswa no kurwanya ubushyuhe.
Kugereranya Kurwanya Kurwanya Kurwanya no Kugereranya Ubushyuhe
Kurwanya ruswa:
- 316 Icyuma: Bitewe na molybdenum, ifite imbaraga zo kurwanya ruswa kuruta 304, cyane cyane kurwanya chloride.
- 304L Icyuma: Hamwe na karubone nkeya, ifite kandi imbaraga zo kurwanya ruswa, ibereye ibidukikije byangirika. Kurwanya kwangirika kwayo kurutwa gato na 316 ariko birahenze cyane.
Kurwanya Ubushyuhe:
- 316 Icyuma: Ububiko bwa chromium-nikel-molybdenum butanga ubushyuhe bwiza kuruta 304 ibyuma bitagira umwanda, cyane cyane na molybdenum yongerera imbaraga okiside.
- 304H Icyuma: Bitewe na karubone nyinshi, manganese nkeya, hamwe na silikoni nyinshi, irerekana kandi ubushyuhe bwiza mubushyuhe bwinshi.
Ibyuma Byuma Byakoreshejwe
304 Icyuma: Igiciro cyibanze kandi gihindagurika, gikoreshwa cyane mubwubatsi, gukora, no gutunganya ibiryo.
304L Icyuma: Carbone yo hasi ya 304, ikwiranye nubuhanga bwa chimique na marine, hamwe nuburyo busa bwo gutunganya kugeza 304 ariko bikwiranye nibidukikije bisaba kurwanya ruswa cyane no kumva neza ibiciro.
304H Icyuma: Ikoreshwa muri superheater hamwe nubushyuhe bwa bombo nini, imiyoboro ya parike, guhinduranya ubushyuhe munganda za peteroli, nibindi bikorwa bisaba kurwanya ruswa neza nubushyuhe bwo hejuru.
316 Icyuma.
