Chitsulo chosapanga dzimbiri 254SMO-F44
Mayina Ofanana Amalonda: 254Mo, F44, UNS 31254 , W.Nr 1.4547
Aloyi F44(254Mo)ndi kuchuluka kwa molybdenum, chromium ndi nayitrogeni, chitsulo ichi chimakhala ndi kukana kwabwino kwambiri pakubowola ndi kuwononga dzimbiri.Copper imathandizira kukana dzimbiri mwa ena mwa asidi.Kuphatikiza apo, chifukwa cha kuchuluka kwake kwa faifi tambala, chromium ndi molybdenum, kotero kuti 254SMO ikhale ndi kupsinjika kwamphamvu kwamphamvu yowononga dzimbiri.

Chifukwa chiyani 254SMo (F44) ?
•Kugwiritsidwa ntchito kosiyanasiyana kosiyanasiyana kwawonetsa kuti ngakhale kutentha kwa iin, 254SMO m'madzi a m'nyanja kumakhalanso kugonjetsedwa ndi kuwonongeka kwa ntchito ya dzimbiri, mitundu yochepa chabe yazitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito.
•254SMO monga pepala loyera lofunikira popanga yankho la acidic ndi yankho la halide oxidative dzimbiri kukana ndi kukana dzimbiri lingayerekezedwe ndi zolimba kwambiri m'munsi mwa aloyi ya faifi tambala ndi titaniyamu.
•254SMO chifukwa cha kuchuluka kwa nayitrogeni, kotero mphamvu yake yamakina kuposa mitundu ina yazitsulo zosapanga dzimbiri za austenitic ndizokwera.Kuphatikiza apo, 254SMO imakhalanso yolimba kwambiri komanso imakhudza mphamvu komanso kutsekemera kwabwino.
•254SMO yokhala ndi molybdenum yochuluka imatha kupangitsa kuti ikhale yochuluka kwambiri ya okosijeni mu annealing, yomwe pambuyo poyeretsa asidi ndi pamwamba kuposa zitsulo zosapanga dzimbiri ndizofala kwambiri kuposa pamwamba.Komabe, sizinakhudze kwambiri kukana kwa dzimbiri kwa chitsulo ichi.
254SMo (F44) Munda wofunsira:
254SMO ndi zinthu zambiri zomwe zingagwiritsidwe ntchito m'mafakitale ambiri:
1. Mafuta, zida za petrochemical, zida zamafuta amafuta, monga mvuto.
2. Zida zothira zamkati ndi mapepala, monga kuphika zamkati, kuthirira, kutsuka zosefera zomwe zimagwiritsidwa ntchito mu mbiya ndi ma cylinder pressure rollers, ndi zina zotero.
3. Zida zamagetsi zamagetsi zamagetsi, kugwiritsa ntchito zigawo zazikuluzikulu: nsanja yoyatsira, chitoliro ndi mbale yoyimitsa, gawo lamkati, makina opopera.
4. Njira yopangira madzi a m'nyanja kapena m'nyanja, monga makina opangira magetsi ogwiritsira ntchito madzi a m'nyanja kuziziritsa Condenser yokhala ndi mipanda yopyapyala, kuchotsa mchere wa zida zopangira madzi a m'nyanja, zitha kugwiritsidwa ntchito ngakhale madzi sangayende pa chipangizocho.
5. Makampani ochotsa mchere, monga zida zochotsera mchere kapena zochotsera mchere.
6. Kutentha kwa kutentha, makamaka m'malo ogwirira ntchito a chloride ion.
