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% nabyo 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 guhangana n’amazi yo mu nyanja, 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, uburyo bwo gukora buragoye. Mubisanzwe, abantu barashobora kwishingikiriza gusa
inzira gakondo yo gukora ibi byuma 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 desulfurizasi 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:
Ibicuruzwa birambuye:
Ibicuruzwa bifitanye isano:
Dufite ibikoresho bigezweho. Ibicuruzwa byacu byoherezwa muri Amerika, Ubwongereza nibindi, bikishimira izina ryabakiriya muburyo bwuburayi kuri 1.75 Umuyoboro w’icyuma - 254SMO UNS S31254 1.4547 umuyoboro udafite ingese - Huaxin, Ibicuruzwa bizatanga ku isi yose, nkibi nka: Espagne, Uburayi, Ositaraliya, Niba hari ibicuruzwa byujuje ibyifuzo byawe, ibuka kutumva neza. Turizera ko ikibazo cyawe cyangwa ibisabwa byose bizahita byitabwaho, ibicuruzwa byujuje ubuziranenge, ibiciro byoroheje hamwe n’ibicuruzwa bihendutse. Twakire byimazeyo inshuti kwisi yose guhamagara cyangwa kuza gusura, kugirango tuganire kubufatanye ejo hazaza heza!
