Bayani: A312 na'urar lantarki ce ta bakin ƙarfe ta Cr23Ni13Mo2 mai rufin calcium na titanium. Ana iya amfani da shi don AC da DC tare da kyakkyawan aikin aiki. Yana da juriya ga tsatsa, tsagewa, da iskar shaka fiye da A302 saboda ƙarfe da aka ajiye yana ɗauke da molybdenum.
Aikace-aikace: Ana amfani da shi don walda irin wannan akwati na bakin karfe mai jure tsatsa daga sinadarin sulfuric acid (ammonia sulfide), kuma ana iya amfani da shi don walda rufin bakin karfe, farantin karfe mai rufi da ƙarfe daban-daban.
Sinadarin sinadarai na ƙarfen walda(%):

Sanarwa:
- Dole ne a gasa wutar lantarki na tsawon awa 1 a kusan 150℃ kafin a fara aikin walda;
- Saboda zurfin shigar ciki ba shi da zurfi yayin walda ta AC, ya kamata a yi amfani da wutar lantarki ta DC gwargwadon iyawa don samun zurfin shigar ciki. Kuma kada wutar ta yi girma sosai don guje wa jajayen sandar walda.
