Intangiriro
TheASTM A312 Utari S30815 253Ma Umuyoboro wicyumani imikorere-yohejuru austel ibyuma bidafite ibyuma bizwi kubijyanye no kurwanya ibirenze okiside ndende, ruswa, hamwe nibintu byiza bya imashini yubupfumu bukabije.253mayateguwe byumwihariko kuri serivisi mubisabwa bisaba gushikama ubushyuhe bwinshi, cyane cyane munganda no kuvura indwara. Kurwanya indashyikirwa ku gupima, karuvatisation, hamwe na okiside rusange bituma bigira ibikoresho byizewe kubidukikije bikabije.
Iki cyiciro cyicyuma kidafite aho gikoreshwa cyane mu nganda zinganda zinganda kandi ni byiza kuri porogaramu aho imbaraga nyinshi n'indaya zo kurwanya okiside ari ingenzi.
AMABANGA N'UBUNTU
TheASTM A312 Utari S30815 253Ma Umuyoboro wicyumaikorerwa hakurikijwe amahame akurikira:
- ASTM A312: Ibisobanuro Bisanzwe kubadafite akamaro, gusudira, kandi bikonje cyane bikonje bya ausonitique ibyuma bitagira ingano
- Sin S30815: Sisitemu yubuhure yibikoresho igaragaza ibi nkumuyaga mwinshi wanduye.
- En 10088-2: Ibipimo by'Uburayi byo kubyuma bidafite ingaruka, bikubiyemo ibisabwa kuri iyi ngingo, imitungo, no kwipimisha.
Ibigize imiti(% kuburemere)
Imiti ya253MA (SNO S30815)yateguwe kugirango itange ingwate nziza kuri okiside nimbaraga zubushyuhe bwinshi. Ibihimbano bisanzwe ni ibi bikurikira:
| Element | Ibihimbano (%) |
| Chromium (cr) | 20.00 - 23.00% |
| Nikel (ni) | 24.00 - 26.00% |
| Silicon (si) | 1.50 - 2.50% |
| Manganese (MN) | 1.00 - 2.00% |
| Karubone (c) | ≤ 0.08% |
| Fosiphorus (p) | ≤ 0.045% |
| Sulfure (s) | ≤ 0.030% |
| Azote (n) | 0.10 - 0.30% |
| Icyuma (FE) | Kuringaniza |
Ibiranga Ibikoresho: Ibiranga Urufunguzo
253ma. Ibi bituma bigira intego kubisabwa mubidukikije bikabije, nkitanura no guhanahana ubushyuhe. Ibikoresho bifite ibirimo bya chromium na Nikel, bitanga imbaraga nziza kuri okiside kubushyuhe kugeza 1150 ° C (2100 ° F (2100 ° F (2100 ° F).

INZIRA YAKOMEYE: Ubukorikori bwo gushushanya
Gukora253ma imiyoboro y'ibyumaikurikira uburyo bugezweho bwo kubyara kugirango habeho ubuziranenge kandi iramba:
- Inganda zidafite imiyoboro: Byakozwe binyuze mubirori, gutobora, no kurambura inzira zo gukora imiyoboro idafite ubunini hamwe nu mwoboni wurukuta rumwe.
- Inzira ikonje: Gushushanya ubukonje cyangwa inzira zigenda zikoreshwa kugirango ugere kubipimo nyabyo nubuso bwiza.
- Kuvura ubushyuhe: Imiyoboro ihamye ubushyuhe kubushyuhe bwihariye kugirango yongere imitungo yabo nubushyuhe bwinshi.
- Gutora & pasivation: Imiyoboro iratorwa kugirango ikureho ingano na oxide film kandi ihabwa kurega kugirango igabanye ibindi.
Kwipimisha no kugenzura: Ubwishingizi bwiza
Amashanyarazi akurikira protocole ihamye kugirango irebe ireme rya253ma imiyoboro y'ibyuma:
- Isesengura ry'imiti: Yagenzuye ukoresheje tekinike yijisho kugirango wemeze ko aly yahuye nibigize.
- Kwipimisha: Amakimbirane, gukomera, no kwipimisha kugirango ugenzure imikorere yibikoresho mubushyuhe butandukanye.
- Ibizamini bya hydrostatike: Imiyoboro yipimisha kuramba kugirango habeho imikorere yuzuye.
- Ikizamini kidasenya (NDT): Harimo Ultrasonic, Eddy Ibiriho, na Irari ryipimisha kugerageza kumenya ubumwe cyangwa hejuru yimbere.
- Icyerekezo & urwego: Buri muyoboro uragenzurwa havomekira hejuru, kandi urwego rwukuri rugenzurwa kubisobanuro.
Kubindi bisobanuro cyangwa ibisobanuro byihariye, hamagara imbeba ya Wormic uyumunsi!
