440C zosapanga dzimbiri lathyathyathya balandi chitsulo chosapanga dzimbiri chapamwamba chomwe chimadziwika ndi kuphatikiza kwapadera kwa kukana kuvala komanso kukana dzimbiri. Ndi ya banja la zitsulo zosapanga dzimbiri la martensitic ndipo imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chakuchita bwino kwambiri.

Nawa mfundo zazikuluzikulu zoyambira zitsulo zosapanga dzimbiri 440C:
1. Mapangidwe: 440C zitsulo zosapanga dzimbiri lathyathyathya zimapangidwa makamaka ndi chromium (16-18%), carbon (0.95-1.20%), ndi zinthu zina zazing'ono monga manganese, silicon, ndi molybdenum.
2. Wear Resistance: 440C zitsulo zosapanga dzimbiri lathyathyathya ndi lodziwika bwino chifukwa cha kukana kwamphamvu kwa mavalidwe, ndikupangitsa kuti likhale loyenera kugwiritsa ntchito zida zonyezimira, zida zodulira, ma bere, ndi zida zosavala.
3. Kukaniza kwa Corrosion: Ngakhale kuti ndi chitsulo chosapanga dzimbiri cha carbon, 440C imasonyeza kukana bwino kwa dzimbiri.
4. Kulimba ndi Mphamvu: 440C chitsulo chosapanga dzimbiri lathyathyathya ili ndi kuuma kwakukulu ndi mphamvu zambiri, kupereka kukhalitsa ndi moyo wautali pamagwiritsidwe ntchito ovuta.
