Fe

1. Introduce – It has better ductility than aluminum, but its strength increases when mixed with a small amount of carbon – It accounts for more than 90% of global metal production * Types of Fe 1) Pure Iron √ Carbon content less than 0.035% 2) Mild steel √ Iron with a lower carbon content than steel √ Carbon content 0.05–0.25% 3) Hardenable Steel √ Iron with a small amount of carbon added to increase the hardness of pure iron (1) Carbon Steel: An alloy of Fe and C containing small amounts of Si, Mn, P, S, etc. (2) Alloy Steel: An alloy of Fe and C containing V, Mo, Co, etc. (3) St...
