According to the IIW recommended formula, the carbon equivalent of AISI 1018 steel is 0.35%. To calculate this value, follow these steps:
Collect data on the maximum allowed composition of alloying elements in AISI 1018 steel: C: 0.20%, Mn: 0.90%, P: 0.04%, S: 0.05%.
Use the values in the IIW formula for carbon equivalent:
CE = C + Mn/6 + (Cu + Ni)/15 + (Cr + Mo + V)/5 = 0.20 + 0.90/6 + 0 = 0.35
