420J1 420J2 bakin karfe tsiri
Takaitaccen Bayani:
Zare-zanen ƙarfe na 420J1 da 420J2 nau'ikan kayan ƙarfe ne guda biyu da aka saba amfani da su a cikin jerin ƙarfen bakin ƙarfe na martensitic. Suna da wasu bambance-bambance a cikin abubuwan da ke cikin sinadarai da halaye. Ga taƙaitaccen bayani game da kowannensu:
1. Zaren bakin karfe na 420J1: 420J1 ƙarfe ne mai ƙarancin carbon mai ƙarfi da ƙarfi. Sinadarin sa yawanci ya ƙunshi kusan kashi 0.16-0.25% na carbon, kusan kashi 1% na chromium, da ƙananan adadin molybdenum. 420J1 yana ba da juriyar tsatsa, aikin yankewa, da kuma kaddarorin niƙa. Ana amfani da shi sosai don yin wuƙaƙe, kayan aikin tiyata, sassan injina, da wasu aikace-aikacen da ba sa jure lalacewa.
2. Zaren bakin karfe na 420J2: 420J2 ƙarfe ne mai matsakaicin carbon mai ƙarfi da juriyar lalacewa. Sinadarin sa yawanci yana ɗauke da kusan kashi 0.26-0.35% na carbon da kuma kusan kashi 1% na chromium. 420J2 yana da yawan sinadarin carbon idan aka kwatanta da 420J1, wanda ke haifar da ƙaruwar tauri da aikin yankewa. Ana amfani da shi akai-akai don kera wuƙaƙe, ruwan wukake, kayan aikin tiyata, maɓuɓɓugan ruwa, da wasu sassan injina.
