420J1 420J2 bakin karfe tsiri
Takaitaccen Bayani:
420J1 da 420J2 bakin karfe tube iri biyu na kowa bakin karfe kayan da ke cikin martensitic bakin karfe jerin. Suna da wasu bambance-bambance a cikin sinadarai da halaye. Ga taƙaitaccen bayanin kowane:
1. 420J1 bakin karfe tsiri: 420J1 ne a low-carbon bakin karfe da high taurin da ƙarfi. Abubuwan sinadaran sa yawanci sun haɗa da kusan 0.16-0.25% carbon, kusan 1% chromium, da ƙananan adadin molybdenum. 420J1 yana ba da juriya mai kyau na lalata, aikin yankewa, da kaddarorin niƙa. An fi amfani da shi don yin wuƙaƙe, kayan aikin tiyata, sassa na inji, da wasu aikace-aikace masu jure lalacewa.
2. 420J2 bakin karfe tsiri: 420J2 ne a matsakaici-carbon bakin karfe da high taurin da sa juriya. Abubuwan sinadaran sa yawanci ya ƙunshi kusan 0.26-0.35% carbon da kusan 1% chromium. 420J2 yana da mafi girman abun ciki na carbon idan aka kwatanta da 420J1, wanda ya haifar da ƙara yawan taurin da yanke aikin. Ana amfani da shi akai-akai don kera wukake, wukake, kayan aikin tiyata, maɓuɓɓugan ruwa, da wasu sassa na inji.
