Puddling, by which the molten metal is still further exposed to a blast of air and oxidising substances in a reverberatory furnace. The remainder of the carbon is thus removed, and clotty lumps or "puddle halls " of pure iron appear.

    Rust chemistry

    It is an electrochemical process which requires the presence of water, oxygen and an electrolyte. In the absence of any one of these rusting does not occur to any significant extent. In air, a relative humidity of over 50% provides the necessary amount of water and at 80% or above corrosion of bare steel is worse.

    Unlike ferrous oxides, the hydroxides do not adhere to the bulk metal. As they form and flake off from the surface, fresh iron is exposed, and the corrosion process continues until either all of the iron is consumed or all of the oxygen, water, carbon dioxide, or sulfur dioxide in the system are removed or consumed.

    Corrosion of Iron

    The corrosion of iron, better known as rusting, is an oxidationreduction process that destroys iron objects left out in open, moist air. In the United States alone, it is estimated that the cost of corrosion, in equipment maintenance, repair, and replacement, exceeds 300 billion per year.
