440a 440b 440C Mendulo:

Zokhala ndi mpweya ndi kuuma kwa 440a-440b-440c zimachulukitsa bwino kuchokera ku ABC (A-0.75%, B-0.2%). The 440c ndi chitsulo chosapanga dzimbiri kwambiri chokhala ndi ma 56-58 rc. Zitsulo zitatuzi zimakhala ndi dzimbiri zabwino, 440A ndiye yabwino kwambiri, ndipo 440c ndiyotsika kwambiri. The 440c ndiofala kwambiri. Kuphatikizika kwa mankhwala kwa chitsulo chosapanga dzimbiri kumadziwika ndi kuwonjezera kwa zinthu monga Molybdenum, kung'ambika, ndi niobium, ndi 10% -27% -27%. Popeza minyewa ndi cubic yopangidwa ndi thupi, mphamvu imatsikira kwambiri kutentha kwambiri. Pansi pa 600 ° C, mphamvu yayikulu ndi yapamwamba kwambiri pakati pa mitundu yonse ya chitsulo chosapanga dzimbiri, ndipo mphamvu zogulira zimakhalanso zapamwamba. 440a ali ndi katundu wabwino kwambiri komanso kuumitsa ndi kuuma kwake. Imakhala ndi mphamvu yayitali kuposa 440b chitsulo ndi 440c chitsulo. 440b imagwiritsidwa ntchito podula zida, zoyezera zida, ziwonetsero ndi mavuvu. Ili ndi kuuma kwakukulu kuposa 440a chitsulo komanso kulimba kwambiri kuposa 440c chitsulo. The 440c ili ndi kuuma kwakukulu kwa chitsulo chonse chopanda chosapuma ndi kutentha ndipo kumagwiritsidwa ntchito kwadzidzidzi. 440F ndi kalasi yachitsulo yomwe imakulitsa zosavuta zodulira 440c chitsulo cha matalala.
