254SMo Material Properties
254SMO ndi chitsulo chosapanga dzimbiri cha austenitic.Chifukwa cha kuchuluka kwake kwa molybdenum, imakhala ndi mphamvu yolimbana ndi kupindika komanso kuwonongeka kwa ming'alu.Gulu lazitsulo zosapanga dzimbiri linapangidwa ndikupangidwa kuti ligwiritsidwe ntchito m'malo okhala ndi halide monga madzi a m'nyanja.254SMO imakhalanso ndi kukana kwabwino kwa dzimbiri yunifolomu.Makamaka mu ma asidi okhala ndi halide, chitsulocho chimaposa chitsulo chosapanga dzimbiri wamba.C yake ili ndi<0.03%, kotero amatchedwa pure austenitic zosapanga dzimbiri (<0.01% imatchedwanso super austenitic chitsulo chosapanga dzimbiri).Chitsulo chosapanga dzimbiri chapamwamba ndi mtundu wachitsulo chapadera chosapanga dzimbiri.Choyamba, ndi chosiyana ndi chitsulo chosapanga dzimbiri wamba pakupanga mankhwala.Amatanthawuza chitsulo chosapanga dzimbiri chopanda chitsulo chokhala ndi faifi wokwera, chromium wokwera ndi molybdenum wokwera.Pakati pawo, imodzi yotchuka kwambiri ndi 254SMo yomwe ili ndi 6% Mo. Chitsulo chamtunduwu chimakhala ndi kukana kwabwino kwa dzimbiri, ndipo chimakhala ndi kukana kwabwino kwa pitting corrosion (PI≥40) ndipo Chimakhala ndi kupanikizika kwabwino kwa dzimbiri ndipo ndi m'malo mwa Ni- ma aloyi opangidwa ndi titaniyamu.Kachiwiri, potengera kutentha kwambiri kapena kukana kwa dzimbiri, imakhala ndi kukana kutentha kwambiri kapena kukana kwa dzimbiri, komwe sikungalowe m'malo mwa zitsulo zosapanga dzimbiri 304.Kuonjezera apo, kuchokera kumagulu azitsulo zosapanga dzimbiri, mawonekedwe a metallographic a chitsulo chosapanga dzimbiri ndi chokhazikika cha austenite metallographic.
Popeza chitsulo chosapanga dzimbiri chapadera ichi ndi chinthu chopangidwa ndi alloy apamwamba, kupanga kupanga kumakhala kovuta kwambiri.Nthawi zambiri, anthu amangodalira njira zachikhalidwe kuti apange chitsulo chosapanga dzimbiri chapadera, monga kulowetsedwa, kupangira, kugudubuza ndi zina zotero.
254SMo Material Application Area
1. Nyanja: zomanga zam'madzi m'malo am'madzi, kutulutsa madzi am'nyanja, ulimi wamadzi am'nyanja, kusinthanitsa kutentha kwamadzi am'nyanja, ndi zina zambiri.
2. Munda wachitetezo cha chilengedwe: chipangizo cha flue gas desulfurization chopangira mphamvu zotentha, kuthira madzi oyipa, etc.
3. Mphamvu yamagetsi: kupanga mphamvu za nyukiliya, kugwiritsa ntchito malasha mokwanira, kutulutsa mphamvu zamafunde am'nyanja, ndi zina zambiri.
4. Munda wa Petrochemical: kuyenga mafuta, zida zamagetsi ndi mankhwala, ndi zina.
5. Munda wa chakudya: kupanga mchere, kuphika msuzi wa soya, ndi zina zotero.
6. High-concentration chloride ion chilengedwe: makampani opanga mapepala, zipangizo zosiyanasiyana zoyeretsera
