Incamake y'icyuma kitagira umugese
Icyuma kitagira umwanda: Ubwoko bw'icyuma kizwiho kurwanya ingese no kudacika ingese, kirimo nibura 10.5% bya chromium na karuboni ntarengwa 1.2%.
Ibyuma bitanduye ni ibikoresho bikoreshwa cyane mu nganda zitandukanye, bizwiho kurwanya ingese no gukoresha ibintu byinshi. Mu byiciro byinshi by'ibyuma bitanduye, 304, 304H, 304L, na 316 ni byo bikunze gukoreshwa cyane, nk'uko bivugwa mu gipimo cya ASTM A240/A240M kuri "Icyuma kitanduye cya Chromium na Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and General Applications."
Izi ngeri enye ziri mu cyiciro kimwe cy'icyuma. Zishobora gushyirwa mu byiciro bya austenitic stainless steels hashingiwe ku miterere yazo ndetse no mu byiciro 300 bya chromium-nickel stainless steels hashingiwe ku miterere yazo. Itandukaniro ry'ibanze riri mu miterere yazo ya shimi, kurwanya ingese, kurwanya ubushyuhe, n'aho zikoreshwa.
Icyuma gikozwe muri Austenitic Stainless Steel: Mbere na mbere igizwe n'imiterere ya kristu y'ikibe iri hagati mu maso (γ phase), idakoresha ingufu za rukuruzi, kandi ikomeje gukoreshwa cyane binyuze mu gukora ibintu bikonje (bishobora gutera imbaraga za rukuruzi). (GB/T 20878)
Ibigize imiti n'igereranya ry'imikorere (Hashingiwe ku mahame ya ASTM)
304 Icyuma Kidafunze:
- Ibikubiye mu nkuru: Irimo kromiyumu iri hagati ya 17.5-19.5% na nikeli iri hagati ya 8-10.5%, hamwe n'agace gato ka karuboni (munsi ya 0.07%).
- Imiterere ya mekanike: Igaragaza imbaraga nziza zo gukurura (515 MPa) no kurekura (hafi 40% cyangwa irenga).
Ibyuma bita 304L by'icyuma kitagira umugese:
- Ibikubiye mu nkuru: Bisa na 304 ariko bifite ingano ya karuboni yagabanutse (munsi ya 0.03%).
- Imiterere ya mekanike: Bitewe n'uko karuboni irimo karuboni nkeya, imbaraga zo gukurura ziri munsi gato ya 304 (485 MPa), hamwe n'uburebure bumwe. Ingano nke ya karuboni yongera imikorere yayo yo gusudira.
Icyuma kitagira umwanda cya 304H:
- Ibikubiye mu nkuru: Ingano ya karuboni isanzwe iri hagati ya 0.04% na 0.1%, hamwe na manganese yagabanutse (kugeza kuri 0.8%) na silikoni yiyongera (kugeza kuri 1.0-2.0%). Ingano ya kromu na nikeli isa na 304.
- Imiterere ya mekanike: Ingufu zo gukurura (515 MPa) no kurekura ni kimwe na 304. Ifite imbaraga n'ubukomezi bwiza mu bushyuhe bwinshi, bigatuma ikwiriye ahantu hashyuha cyane.
316 Icyuma Kidafunze:
- Ibikubiye mu nkuru: Irimo 16-18% ya chromium, 10-14% ya nikeli, na 2-3% ya molybdenum, ifite ingano ya karuboni iri munsi ya 0.08%.
- Imiterere ya mekanike: Ingufu zo gukurura (515 MPa) no kurekura (birenze 40%). Ifite ubudahangarwa bwo kwangirika cyane.
Ukurikije igereranya ryavuzwe haruguru, biragaragara ko izo ngeri enye zifite imiterere isa cyane ya mekanike. Itandukaniro riri mu miterere yazo, ibyo bigatuma habaho itandukaniro mu kurwanya ingese no kurwanya ubushyuhe.
Kugereranya Ubudahangarwa bw'Icyuma Kidashonga n'Ubushyuhe
Ubudahangarwa bw'inkongi:
- 316 Icyuma Kidafunze: Bitewe n'uko molybdenum ihari, ifite ubushobozi bwo kurwanya ingese kurusha 304 series, cyane cyane iyo irwanya ingese ya chloride.
- Ibyuma bita 304L by'icyuma kitagira umugese: Kubera ko ifite karubone nkeya, inafite ubushobozi bwo kurwanya ingese, ikwiriye ahantu hashobora kwangirika. Irwanya ingese iri hasi gato kuri 316 ariko ihendutse cyane.
Ubudahangarwa bw'ubushyuhe:
- 316 Icyuma Kidafunze: Igizwe na chromium-nickel-molybdenum nyinshi itanga ubushobozi bwo kurwanya ubushyuhe kurusha icyuma kidashonga cya 304, cyane cyane ko molybdenum yongera ubushobozi bwo kurwanya ogisijeni.
- Icyuma kitagira umwanda cya 304H: Bitewe n'uko ifite karuboni nyinshi, manganese nke, na silikoni nyinshi, kandi igaragaza ubushyuhe bwiza iyo ubushyuhe buri hejuru.
Imirima yo gukoresha ibyuma bitagira umuze
304 Icyuma Kidafunze: Ni urwego rw'ibanze ruhendutse kandi rukoreshwa mu buryo butandukanye, rukoreshwa cyane mu bwubatsi, mu nganda no mu gutunganya ibiribwa.
Ibyuma bita 304L by'icyuma kitagira umugese: Verisiyo ya 304 ikoresha karubone nkeya, ikwiriye gukoreshwa mu buhanga mu by'ubutabire n'ubwato, ifite uburyo bwo kuyitunganya busa na 304 ariko ikwiriye cyane ahantu hasaba kurwanya ingese nyinshi no kwihuta mu biciro.
Icyuma kitagira umwanda cya 304H: Ikoreshwa mu byuma bishyushya cyane n'ibishyushya byo mu byuma binini, imiyoboro y'umwuka, ibikoresho bihindura ubushyuhe mu nganda zikora peteroli, n'ibindi bikoresho bisaba kurwanya ingese neza no gukora neza mu bushyuhe bwinshi.
316 Icyuma Kidafunze: Ikoreshwa cyane mu nganda zikora imyanda n'impapuro, inganda zikomeye, ibikoresho byo gutunganya no kubika imiti, ibikoresho byo gutunganya imyanda, ibikoresho by'ubuvuzi n'imiti, peteroli na gaze byo mu nyanja, ibidukikije byo mu mazi, n'ibikoresho byo guteka byo mu rwego rwo hejuru.
