A takaice bayanin:
420J1 da 420J2 Bakin Karfe Tube sune nau'ikan kayan karfe guda biyu waɗanda suke na Martensitic Bakin Karfe Sakin Karfe. Suna da wasu bambance-bambance a cikin tsarin sunadarai da halaye. Ga taƙaice taƙaitaccen bayyanar kowane:
1. 420J1 Sirbir: 420J1 shine low-carbon bakin karfe da ƙarfi da ƙarfi. Abubuwan da ke tattare da sunadarai yawanci sun haɗa da kusan carbon 0.16-0.25% carbon, kusan 1% chromium, da ƙananan adadin molybdenum. 420J1 yana ba da kyawawan juriya na lalata, suna yin aiki, da kaddarorin nagar. Ana amfani dashi don yin wukake, kayan masarufi, sassan injin, da wasu aikace-aikacen da suka sanyawa.
2. 420J2 Sirress StrIp: 420J2 shine matsakaici-carbon bakin karfe tare da babban ƙarfi da kuma sa juriya. Abubuwan da ke tattare da su sunadarai yawanci sun ƙunshi kusan 0.26-0.35% Carbon kuma kusan 1% Chromium. 420J2 yana da abun ciki mafi girma mafi girma idan aka kwatanta da 420J1, wanda ya haifar da ƙara ƙarfi da yankan aiki. Ana amfani da shi akai-akai don sanyayen masana'antu, ruwan bashin, kayan kida, maɓuɓɓugan ruwa, da wasu sassan inji.
