AISI 4140 SCM440 DIN 42CrMo4 1.7225 Xaraashka Wareegga Birta ah ee Daawaha
Faahfaahinta Alaabta
AISI 4140 waxaa lagu qeexaa sida bir daawaha hoose oo leh 1% Cr-Mo sida xoojinta walxaha alloy. Marka la barbar dhigo AISI 4130, waxay leedahay kaarboon sare oo dheellitiran oo xoog leh, adkaansho, xoqan iyo iska caabin saameyn leh iyo awoodaha daaweynta kulaylka, laakiin AISI 4140 waxaa guud ahaan lagu bixiyaa xaalad demmin iyo qallafsanaan adag 28-32HRC.
4140 waxa uu leeyahay xoog sare, karti adag, adayg, iyo qallafsanaan inta lagu jiro deminta.Waxay leedahay xoog gurguurta oo sarreeya iyo xoog adkaysi heerkul sare.Waxaa loo isticmaalaa wax soo saarka foornada oo u baahan xoog sare iyo qaybo ka weyn oo la demiyo iyo kuwa dabci ah oo ka badan 4135 birta, sida qalabka waaweyn ee jiid jiidashada, qalabka gudbinta xoojisa, faashashka danbe, ulo isku xidha iyo clips guga oo aad u raran.
