AISI D2 1.2379 Qalabka Birta ah
Sharaxaad Gaaban:
D2 waa bir aad u tayo sare leh oo chromium badan leh oo loo yaqaan iska caabinta xirashada iyo adkeysiga wanaagsan. Badanaa waxaa loo isticmaalaa codsiyada sida nadiifinta makiinada, sameynta makiinada, iyo qalabka jarista.
1.2379 Qalabka Birta ah ee Birta ah:
Birta D2, oo laga heli karo qaabab wareegsan iyo kuwa saxan, ayaa ku habboon soo saarista qaabab shaqo qabow oo leh qaybo ballaaran, qaabab adag, iyo shuruudo adag oo loogu talagalay iska caabbinta saameynta iyo iska caabbinta xirashada. Sidoo kale loo yaqaan birta DIN 1.2379 iyo JIS SKD11, waxay ku dhacdaa qaybta birta caaryada shaqada qabow ee kaarboon sare leh, oo chromium sare leh. Birtan waxay ku raaxaysanaysaa isticmaal ballaaran oo adduunka oo dhan ah sababtoo ah adkaanshaheeda gaarka ah iyo iska caabbinta cajiibka ah ee oksaydhka heerkulka sare leh. Ka dib marka la damiyo oo la nadiifiyo, birta D2 waxay muujisaa sifooyin aad u fiican oo ka hortagga daxalka, isbeddel yarna wuxuu dhacaa inta lagu jiro hababka daaweynta kulaylka.
