Chitsulo chosapanga dzimbiri 304,304L,304H

Chiyambi cha malonda
Chitsulo chosapanga dzimbiri 304 ndi chitsulo chosapanga dzimbiri 304L amadziwikanso kuti 1.4301 ndi 1.4307 motsatana. 304 ndiye chitsulo chosapanga dzimbiri chosunthika komanso chogwiritsidwa ntchito kwambiri. Nthawi zina imatchulidwabe ndi dzina lake lakale 18/8 lomwe limachokera ku 304 kukhala 18% chromium ndi 8% nickel. 304 chitsulo chosapanga dzimbiri ndi kalasi ya austenitic yomwe imatha kukokedwa mozama kwambiri. Katunduyu wapangitsa kuti 304 ikhale giredi yayikulu yomwe imagwiritsidwa ntchito ngati masinki ndi ma saucepan.

304L ndiye mtundu wocheperako wa 304. Amagwiritsidwa ntchito pazinthu zoyezera kwambiri kuti athe kutenthetsa bwino.

304H, mtundu wapamwamba kwambiri wa carbon, umapezekanso kuti ugwiritsidwe ntchito kutentha kwambiri.
