CARBON EQUIVALENT NUMBER (Carbon Steels)

The carbon equivalent number for carbon steel indicates the weldability of the steel, in particular, the carbon equivalent is an indicator of the requirement for preheat to achieve ideal weld properties. Carbon equivalent numbers less than 0.40 should not require preheat. This calculation is for carbon steels only. The calculation of Carbon Equivalent numbers for low alloy steels is presented here.
