How Stainless Steel Products are Produced in 9 Steps ...

Passivation is a non-electrolytic finishing process that makes stainless steel more rust-resistant. The passivation process typically uses nitric or citric acid to remove free iron from the surface. This results in an inert, protective oxide layer that is less likely to chemically react with air and cause corrosion.

Manufacture of Steel - Steel Manufacturing Process and Steps

The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.
