Hephaestus

Since you are told that you are removing common steel making impurities, perhaps you can identify some in your answers.

Every answer has N, P, and S in it.

You are given the difference in the standard weight between the finished product and the raw material. The raw material still includes the weight of the impurities you had to remove.

Since you are given the difference in the standard weight between the finished product and the raw material, you need to add the weight removed to the given weight to find the weight of the 2-3 elements that need to be alloyed in.

You need to find 2-3 elements whose weights sum to the NPS weights plus the given added weight and insert those elements into the remaining letters to make a new word. Make sure to use the standard (abridged) weight.

Notice that the answers you got so far are each 1 letter shorter than the title of the puzzles. You can use that to deduce how many elements may be added into each one.

The elemental symbol for Iron appears in each of the feeder titles.

The length of the puzzle titles are each 1 letter longer than the resulting word after alloying in your 2-3 metals. Since Fe shows up in each title, if you consider it as a single element rather than two letters, it gives a location in each feeder answer.

There are a few sets of numbers in this puzzle. Why not try organizing by a set of numbers and see if that works.

You should order smallest to largest using the total weight of the added alloys.

You will need to repeat the process that you have completed for each of the feeders

Just like for each of the feeders, you need to remove any N, P, or S in your current answer and add in 2-3 elements. The elements you add in have to have a sum weight equal to that of the removed elements plus 237.986.
