AISI D2 1.2379 Qalabka Birta
Sharaxaad Gaaban:
D2 waa kaarboon-sare, qalab chromium-sare ah oo loo yaqaan caabbinta xidhashada wanaagsan iyo adkaanta wanaagsan. Inta badan waxaa loo adeegsadaa codsiyada ay ka midka yihiin dhinta faaruqinta, samaynta dhinta, iyo qalabka goynta.
1.2379 Qalabka Birta Birta:
Birta D2, oo laga heli karo foomamka bar wareega iyo saxanka, waxay ku habboon tahay soo saarista caaryada shaqada qabow ee leh qaybo badan oo isgoys ah, qaabab adag, iyo shuruudo dalbanaya iska caabbinta saamaynta iyo xidhashada caabbinta. Sidoo kale loo yaqaan DIN 1.2379 iyo JIS SKD11 birta, waxay ku dhacdaa qaybta kaarboon-sare, qaboojiyaha qaboojiyaha sare ee birta. Birtaani waxay ku raaxaysataa isticmaalka baahsan ee caalamka oo dhan sababtoo ah qallafsanaantiisa gaarka ah iyo caabbinta cajiibka ah ee heerkulka sare ee oxidation.Ka dib deminta iyo nadiifinta, birta D2 waxay soo bandhigtaa sifooyin ka hortag ah oo aad u fiican, iyo curyaaminta ugu yar waxay dhacdaa inta lagu jiro hababka daaweynta kulaylka.
