440C chitsulo chosapanga dzimbiri chosalalaNdi chinthu chapamwamba kwambiri chachitsulo chosapanga dzimbiri chodziwika bwino chifukwa cha kuphatikiza kwake kwapadera kokana kuwonongeka ndi kukana dzimbiri. Ndi cha banja la chitsulo chosapanga dzimbiri cha martensitic ndipo chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha ntchito yake yabwino kwambiri.

Nazi mfundo zofunika kwambiri zoyambira 440C stainless steel flat bar:
1. Kapangidwe kake: 440C chitsulo chosapanga dzimbiri chopanda utoto chimapangidwa makamaka ndi chromium (16-18%), kaboni (0.95-1.20%), ndi zinthu zina zochepa monga manganese, silicon, ndi molybdenum.
2. Kukana Kuvala: Chitsulo chosapanga dzimbiri cha 440C cholimba chimadziwika chifukwa cha kukana kuvala bwino, zomwe zimapangitsa kuti chigwiritsidwe ntchito pazinthu zodula, zida zodulira, mabearing, ndi zinthu zina zosavala.
3. Kukana Kudzimbidwa: Ngakhale kuti ndi chitsulo chosapanga dzimbiri chokhala ndi mpweya wambiri, 440C imakana bwino dzimbiri.
4. Kulimba ndi Mphamvu: Chitsulo chosapanga dzimbiri cha 440C chili ndi kuuma kwabwino komanso mphamvu zambiri, zomwe zimapangitsa kuti chikhale cholimba komanso chikhale chokhalitsa nthawi yayitali.
