Labarai - "Dukkan-rounder" a cikin Carbon Karfe Plate

Carbon karfe farantin yana daya daga cikin mafi asali nau'i na karfe kayan. Ya dogara ne akan baƙin ƙarfe, tare da abun ciki na carbon tsakanin 0.0218% -2.11% (ma'auni na masana'antu), kuma ya ƙunshi babu ko ƙananan adadin abubuwan haɗin gwiwa. Dangane da abun ciki na carbon, ana iya raba shi zuwa:
Low carbon karfe(C≤0.25%): kyakkyawan tauri, mai sauƙin sarrafawa, Q235 yana cikin wannan rukuni;
Matsakaicin carbon karfe(0.25%)
High carbon karfe(C> 0.6%): tsananin taurin gaske da gaggauwa.

Q235 carbon karfe: definition da core sigogi (GB/T 700-2006 misali)
