Carbon Equivalent (CE) CE = % C + %Mn + %Ni + %Cr + %Cu + %Mo 6 15 5 13 4 Given a chemistry of : .12 carbon, .99 manganese, .0075 nickel, .20 chromium, .05 copper & .15 molybdenum Put the numbers in the formula:
CE = .12 + .99 + .0075 + .20 + .05 + .15
6 15 5 13 4
Then simplify the formula by dividing the top number by the bottom number for each of the elements:
CE = .12 + .99 + .0075 + .20 + .05 + .15 CE = .366846 or .37
Watch for changes in “+” and “-” and the decimal points
