409 430 439 441 443 mbale yachitsulo chosapanga dzimbiri
Kufotokozera za kupanga:
400 mndandanda wazitsulo zosapanga dzimbiri ndi aloyi yachitsulo, carbon ndi chromium. Chifukwa mulibe nickel,
ndi chitsulo chosapanga dzimbiri chopulumutsa nickel, chomwe chimatchedwanso chitsulo chosapanga dzimbiri. 400 mndandanda zitsulo zosapanga dzimbiri zili bwino
maginito chifukwa cha martensitic kapangidwe ndi chitsulo.
400 mndandanda zosapanga dzimbiri ali kukana amphamvu kutentha makutidwe ndi okosijeni, ndi thupi ndi makina
katundu alinso bwino poyerekeza ndi carbon steel. Zambiri zazitsulo zosapanga dzimbiri 400 zimatha kutenthedwa.

Ntchito:
1. 409 chitsulo chosapanga dzimbiri : 409L ili ndi kukana kutentha kwakukulu, imatha kupeza injini yachangu komanso
dongosolo utsi, ndi kuchepetsa makulidwe a dongosolo utsi, amene angathe kuchepetsa mpweya utsi.
409L ili ndi mtengo wotsika, kusinthasintha kwabwino, zokolola zambiri komanso kusintha kosavuta. Ndi mankhwala atsopano okonda zachilengedwe.
2. 430 zitsulo zosapanga dzimbiri: Zokongoletsa nyumba, zigawo zoyatsira mafuta, zida zapakhomo, zida zapanyumba.
430F ndi kalasi yachitsulo yokhala ndi zida zodulira zaulere zomwe zimawonjezedwa ku zitsulo 430, zomwe zimagwiritsidwa ntchito kwambiri popangira ma lathes, mabawuti ndi mtedza.
3. 439 zitsulo zosapanga dzimbiri: Elevator, mapanelo okongoletsera ma escalator; mapanelo okongoletsa zomangamanga, monga zokongoletsa zomangira,
mapaipi omanga; Zigawo zamagalimoto zotulutsa mpweya; makina ochapira bafa lamkati
4. 441 chitsulo chosapanga dzimbiri: Nthawi zambiri, chitoliro chakutsogolo, CONVERTER, ndi zina zotero.
5. 443 Stainless steel: Stainless steel 443 ndi mtundu wa chitsulo chosapanga dzimbiri. Nthawi zambiri amagwiritsidwa ntchito kusintha 304.
Kukana kwake kwa dzimbiri ndi kukonza kwake ndikocheperako kuposa 304, koma mtengo wake ndi wotsika. Amagwiritsidwa ntchito kwambiri mu
zida zamagetsi, ziwiya, zida zakukhitchini, zikepe, uvuni ndi zina.
