254SMO UNS S31254 1.4547 umuyoboro udafite ingese
1. Ibisobanuro byoroshye:
254SMO nicyuma gikomeye cya austenitis.
Urwego rwa GB: 00Cr20Ni18Mo6CuN
Icyiciro mpuzamahanga: 254SMO
Icyiciro gisanzwe cyabanyamerika: UNS S31254
Icyiciro cya EU: W. - Nr 1.4547
Ibipimo byabanyamerika: ASTM A240 / ASME SA-240, ASTM A276, ASTM A182 / ASME SA-182, ASTM A312 / ASME A312
Ingano yubunini: 10 * 2mm kugeza 219 * 15mm cyangwa igenwa ukurikije icyifuzo cyabakiriya
Uburebure: 300mm kugeza 20000mm

4. 254SMO Ibisobanuro ：
a. 254SMO nicyuma cya austenitis. Bitewe na molybdenum nyinshi, ifite imbaraga nyinshi zo kurwanya ruswa
no kwangirika.
b. Ubu bwoko bwibyuma bidafite ingese byatejwe imbere kugirango bikoreshwe mubidukikije birimo igice cya kabiri nkamazi yinyanja. 254SMO nayo ifite ibyiza
Kurwanya ruswa imwe.
c. Cyane cyane muri aside irimo halide, ibyuma biruta ibyuma bisanzwe bidafite ingese. Ibirimo C ni <0.03%, nuko yitwa
ibyuma bitagira ibyuma bya austenitike (<0.01% nanone byitwa super austenitis ibyuma bidafite ibyuma). Ibyuma bidafite ingese ni ubwoko bwibyuma bidasanzwe.
d. Mbere ya byose, iratandukanye nicyuma gisanzwe kitagira ingese mubigize imiti. Yerekeza ku bwoko bw'ibyuma birebire bidafite ibyuma
irimo nikel ndende, chromium ndende na molybdenum nyinshi. Icyamamare cyane ni 254SMo irimo 6% Mo. Ubu bwoko bwibyuma
ifite ibyiza byo kurwanya ruswa.
e. Ifite uburyo bwiza bwo kurwanya ruswa (PI ≥ 40) hamwe no kurwanya ruswa ishobora kwangirika mubihe byamazi yinyanja, aeration, crevice
no gushakisha byihuse.
f. Nibikoresho bisimbuza Ni base alloy na titanium. Icya kabiri, ukurikije ubushyuhe bwo hejuru cyangwa kurwanya ruswa,
ifite ubushyuhe buhebuje bwo kurwanya ubushyuhe cyangwa kurwanya ruswa, idasimburwa ku byuma 304 bidafite ingese. Byongeye,
Kuva mubyiciro byibyuma bidafite ingese, imiterere yicyuma cyumuringa udasanzwe nicyuma gihamye cya austenitis metallographic structure.
g. Nkuko iki cyuma kidasanzwe kitagira umwanda nigikoresho kinini kivanze, inzira yacyo irakomeye. Mubisanzwe, abantu barashobora kwishingikiriza gusa
inzira gakondo yo gukora ibyuma bidasanzwe bidafite ingese, nko gusuka, guhimba, kuzunguruka, nibindi.
5. Gusaba:
1) Inyanja: inyubako zo mu nyanja z’ibidukikije byo mu nyanja, kwangiza amazi yo mu nyanja, ubuhinzi bw’amafi, guhanahana amazi mu nyanja, n'ibindi.
2) Kurengera ibidukikije: ibikoresho bya gaz desulfurisation yo kubyara amashanyarazi, gutunganya amazi mabi, nibindi.
3) Ingufu: kubyara ingufu za atome, gukoresha neza amakara, kubyara amashanyarazi, nibindi.
4) Inganda zikomoka kuri peteroli: gutunganya amavuta, ibikoresho bya shimi, nibindi.
5) Umurima wibiryo: gukora umunyu, guteka soya, nibindi.
6) Ibidukikije byinshi bya chloride ibidukikije: inganda zimpapuro, ibikoresho bitandukanye byo guhumanya.
6. Ubundi buvuzi:
1) Igipolonye
2) Ikimenyetso:
3) Gupakira:
7. Gupakira ibikoresho:
