1012 and S12C are wrought low-carbon (carbon = 0.10–0.15 percent) non-alloy steels that are used in the as rolled, annealed, normalized, or cold worked condition. These steels are characterized by low strength, high ductility, excellent cold formability, and excellent weldability. Within the carbon range of these steel grades, strength and hardness will increase with increase in carbon content and with cold work. Such increases in strength are at the sacrifice of ductility or the ability to withstand cold deformation.
