Intangiriro
ItsindaUmuyoboro w'icyuma gikozwe mu cyuma cya ASTM A312 UNS S30815 253MAni aloyi y'icyuma kitagira umugese izwiho kurwanya cyane ubushyuhe bwinshi, ingese, ndetse n'imiterere myiza ya mekanike mu bushyuhe buri hejuru.253MAYagenewe by'umwihariko serivisi mu bikorwa bisaba ubushyuhe bwinshi, cyane cyane mu nganda zitunganya amatanura n'ubushyuhe. Irwanya cyane gupima, gukaraba, no gutwika ibintu muri rusange bituma iba ibikoresho byizewe mu bidukikije bikomeye.
Ubu bwoko bw'icyuma kitagira umugese bukoreshwa cyane mu nganda zikoresha ubushyuhe bwinshi kandi ni bwiza cyane mu gukoreshwa aho imbaraga nyinshi n'ubudahangarwa bw'amashanyarazi ari ingenzi cyane.
Amahame n'Ibisobanuro
ItsindaUmuyoboro w'icyuma gikozwe mu cyuma cya ASTM A312 UNS S30815 253MAbikorwa hakurikijwe ibipimo ngenderwaho bikurikira:
- ASTM A312: Ibipimo bisanzwe ku miyoboro y'icyuma kitagira umushongi, ivanze, kandi ikonje cyane ikoreshwa mu byuma bitagira umushongi
- UNS S30815: Sisitemu y’imibare ihuriweho ku bikoresho igaragaza ko ibi ari urwego rw’icyuma kitagira umugozi gifite aloyi nyinshi.
- EN 10088-2: Amahame ngenderwaho y’Uburayi ku byuma bitagira umugese, akubiyemo ibisabwa ku miterere y’ibi bikoresho, imiterere yabyo, n’igeragezwa ryabyo.
Ibikoresho bya shimi(% ukurikije uburemere)
Imiterere y'ibinyabutabire bya253MA (UNS S30815)yagenewe gutanga ubushobozi bwo kurwanya ogisijeni neza no gukomera ku bushyuhe bwinshi. Imiterere isanzwe ni iyi ikurikira:
| Igice | Imiterere (%) |
| Chromium (Cr) | 20.00 - 23.00% |
| Nickel (Ni) | 24.00 - 26.00% |
| Silikoni (Si) | 1.50 - 2.50% |
| Manganese (Mn) | 1.00 - 2.00% |
| Karuboni (C) | ≤ 0.08% |
| Fosifore (P) | ≤ 0.045% |
| Sulfure (S) | ≤ 0.030% |
| Azote (N) | 0.10 - 0.30% |
| Icyuma (Fe) | Kuringaniza |
Imiterere y'ibikoresho: Ibiranga by'ingenzi
253MA(UNS S30815) ihuza imbaraga nziza cyane mu bushyuhe bwinshi n'ubudahangarwa bwa ogisijeni. Ibi bituma iba nziza cyane mu bikorwa ahantu hakomeye cyane, nko mu itanura no mu byuma bihindura ubushyuhe. Ibi bikoresho bifite chromium na nikeli nyinshi, bitanga ubudahangarwa bwiza mu bushyuhe bugera kuri 1150°C (2100°F).

- Igipimo cya Poisson: 0.30
- Ubudahangarwa bwiza cyane ku bushyuhe bwinshi, gupima, no gukaraba ibintu mu buryo bwa carburizing.
- Igumana imbaraga kandi ikagira ubushyuhe burenze 1000°C (1832°F).
- Ubudahangarwa bukomeye ku bidukikije birimo aside na alkaline.
- Irwanya kwangirika kw'ingufu bitewe na sulfur na chloride.
- Ishobora kwihanganira ibidukikije bikaze, bigatuma iba nziza cyane mu gutunganya imiti no mu nganda zikoresha ubushyuhe bwinshi.

Uburyo bwo gukora: Ubukorikori bwo gukora neza
Inganda zaImiyoboro y'icyuma kitagira umugese ya 253MAikurikiza uburyo bugezweho bwo gukora kugira ngo igire ireme kandi irambe:
- Gukora imiyoboro idafite umushongi: Bikorwa binyuze mu gusohora, gutobora no kurekura imiyoboro kugira ngo hakorwe imiyoboro idafite umugozi ifite ubugari bw'urukuta bumwe.
- Uburyo bwo gukora mu buryo bukonje: Uburyo bwo gukurura cyangwa gukurura ibintu mu buryo bukonje bukoreshwa kugira ngo hagerwe ku bipimo nyabyo no ku buso bugororotse.
- Uburyo bwo kuvura ubushyuhe: Imiyoboro ishyushya ku bushyuhe bwihariye kugira ngo yongere imiterere yayo ya mekanike n'imikorere yayo mu bushyuhe bwinshi.
- Guteka no gushyuha: Imiyoboro irasharishwa kugira ngo ikureho ibyuma bya skele na oxide hanyuma ikarangizwa kugira ngo ikomeze kwangirika.
Gupima no kugenzura: Kugenzura ubuziranenge
Womic Steel ikurikiza amabwiriza akomeye yo gupima kugira ngo irebe ko ifite ubuziranenge bwo hejuru kuriImiyoboro y'icyuma kitagira umugese ya 253MA:
- Isesengura ry'imiterere y'ibinyabutabire: Yemejwe hakoreshejwe tekiniki za spectroscopic kugira ngo yemeze ko ifu ihuye n'ibice byagenwe.
- Isuzuma rya Mekanike: Gupima imbaraga, ubukana, n'ingaruka kugira ngo harebwe imikorere y'ibikoresho ku bushyuhe butandukanye.
- Isuzuma rya Hydrostatic: Imiyoboro irageragezwa kugira ngo irebe ko iramba kugira ngo idasohoka.
- Isuzuma ritangiza (NDT): Harimo isuzuma rya ultrasound, eddy current, n'isuzuma rya dye penetrant kugira ngo harebwe inenge iyo ari yo yose imbere cyangwa hejuru.
- Igenzura ry'ibigaragara n'ibipimo: Buri muyoboro ugenzurwa n'amaso kugira ngo harebwe uko ubuso bumeze, kandi imiterere yawo igenzurwa hakurikijwe ibipimo.
