Low Carbon Steel General Info
The most affordable of all structural metals is low-carbon steel, usually referred to as mild steel. It is utilized extensively for a variety of purposes.
Strengths
Very low cost, superior to higher carbon steels in terms of toughness, machinability, formability, and weldability. Cold-working improves machinability and strength.
Limitations
Low strength and poor hardenability as compared to higher carbon steels.
Designation
The AISI/SAE designations for carbon steels are 10xx, 11xx, 12xx, and 15xx. Low carbon steels have carbon contents as indicated by the last two numbers, which can reach 30. The EN designations 1.03zz and 1.04zz apply to low carbon steels.
Common uses
Numerous applications, including the reinforcement of concrete, building sections, roofing sheets, vehicle body panels, and cans.
