This adds up to less than 1% of the other ingredients is what?

The content of microstructure and phase composition of Fe-C alloy containing 0.02%,0.2%,0.6%,1.2%,3% and 5% carbon at room temperature

A reward of 5 points is too little! Each carbon content needs to be calculated 2 times,12 times in total. There is too much content. You can calculate it by yourself through the lever law. There is no time for you to calculate here. The following only says 0.02% of these kinds of microstructures and phase compositions: microstructures and phase compositions are ferrite + tertiary cementite.
