Phosphorus and sulfur occur normally in the furnace charge in higher concentrations than are generally permitted in steel and must be removed. Unfortunately the conditions favorable for removing phosphorus are the opposite of those promoting the removal of sulfur. Therefore once these materials are pushed into the slag phase they may revert ...

The only difference between 1018 and 1117 is in sulfur and manganese. The added sulfur in 1117 delivers 33% more tool travel per minute. The lead in 10L18 improves the tool travel by only 27%, despite being almost 3× as much lead as the added sulfur in the 1117. (Lead is 0.35 maximum in 10L18 and sulfur is 0.13 maximum in 1117.)
