carbon (C): carbon content in steel increases, the yield point and the tensile strength increased, but reduced ductility and impact resistance, when the carbon content exceeds 0.23%, weldability deteriorates, and therefore for welding Low alloy structural steel, carbon content of not more than 0.20%. But it also reduces the amount of high-carbon steel resistant to atmospheric corrosion, high carbon steel in the open-air yard would easily corroded; in addition, carbon can be increased sensitivity to cold brittleness and aging steel.
