Certainly seems like it would be! The carbon content of steel is between 0.08 to 1.5 percent.

This process is called sintering (iron) and coking (coal). this was realy interesting i just thought steel was inside the earth, I always thought that steel was made by dumping iron into lava and pulling it out in a day, how old is wonderopolis it is at least 100 years old does that make you 200 , My favorite Wonder was the one about Curveballs.. Iron ore, coke and limestone are fed into the furnace from the top and gradually sink down towards the bottom, getting hotter as they descend.

Today, most steel is made using one of two processes: Blast furnaces use mainly raw materials (iron ore, limestone and coke) with some scrap steel to make steel, whereas Electric Arc Furnaces use mainly scrap steel. Steel I-beam. The Steel Manufacturing Process.

You will, however, find the element that's the primary component of steel: iron. What items do you have around the house that are made of steel?
