4. 254SMO Kufotokozera:
a. 254SMO ndi chitsulo chosapanga dzimbiri cha austenitic. Chifukwa cha kuchuluka kwake kwa molybdenum, imakhala ndi mphamvu yolimbana ndi dzimbiri
ndi dzimbiri mng'alu.
b. Chitsulo chosapanga dzimbiri chamtunduwu chimapangidwa kuti chigwiritsidwe ntchito m'malo okhala ndi ma halides monga madzi am'nyanja. 254SMO ilinso ndi zabwino
kukana dzimbiri yunifolomu.
c. Makamaka mu asidi okhala ndi halide, chitsulocho ndi chapamwamba kuposa chitsulo chosapanga dzimbiri wamba. Zomwe zili mu C ndi <0.03%, motero zimatchedwa
chitsulo chosapanga dzimbiri cha austenitic (<0.01% chimatchedwanso chitsulo chosapanga dzimbiri cha austenitic). Chitsulo chosapanga dzimbiri chapamwamba ndi mtundu wachitsulo chosapanga dzimbiri chapadera.
d. Choyamba, ndi chosiyana ndi chitsulo chosapanga dzimbiri wamba pakupanga mankhwala. Amatanthauza mtundu wa chitsulo chosapanga dzimbiri cha aloyi
okhala ndi faifi tambala, chromium yokwera ndi molybdenum yokwera. Yodziwika kwambiri ndi 254SMo yomwe ili ndi 6% Mo. Mtundu uwu wachitsulo
ali ndi mphamvu yabwino kwambiri yolimbana ndi dzimbiri.
e. Ili ndi kukana kwabwino kwa dzimbiri (PI ≥ 40) komanso kukana kupsinjika kwa dzimbiri pansi pamikhalidwe yamadzi am'nyanja, mpweya, mikwingwirima.
ndi kukwapula kwachangu.
f. Ndilo m'malo mwa Ni base alloy ndi titaniyamu alloy. Kachiwiri, potengera kutentha kwambiri kapena kukana dzimbiri,
ili ndi mphamvu zabwino kwambiri zosatentha kwambiri kapena kuti dzimbiri, zomwe sizingalowe m'malo ndi zitsulo zosapanga dzimbiri 304. Kuphatikiza apo,
kuchokera ku gulu la zitsulo zosapanga dzimbiri, mapangidwe azitsulo zachitsulo chosapanga dzimbiri ndi chokhazikika chachitsulo chosapanga dzimbiri.
g. Monga chitsulo chosapanga dzimbiri chapadera ichi ndi aloyi wapamwamba kwambiri, kupanga kwake kumakhala kovuta kwambiri. Nthawi zambiri, anthu amangodalira
njira zopangira zopanga zitsulo zosapanga dzimbiri zapaderazi, monga kuthira, kufota, kukugudubuza, ndi zina zotero.
5. Kugwiritsa ntchito:
1) Nyanja: malo am'madzi am'madzi am'madzi, kutulutsa madzi am'nyanja, kutulutsa madzi am'nyanja, kusinthanitsa kutentha kwamadzi am'nyanja, etc.
2) Chitetezo cha chilengedwe: chipangizo cha flue gasi desulfurization chopangira mphamvu zotentha, kuthira madzi oyipa, etc.
3) Mphamvu: kutulutsa mphamvu ya atomiki, kugwiritsa ntchito bwino malasha, kutulutsa mphamvu zamafunde, ndi zina zambiri.
4) Makampani a petrochemical: kuyenga mafuta, zida zamankhwala, etc.
5) Munda wa chakudya: kupanga mchere, kuphika msuzi wa soya, etc.
6) Malo okwera kwambiri a chloride: makampani opanga mapepala, zida zosiyanasiyana zoyeretsera.
6. Chithandizo china:
1) Chipolishi
2) Chizindikiro:
3) Kupaka:
