The chemistry of steelmaking. The big picture.

Making iron by removing oxygen from the ore is the first step in the manufacture of steel. Reduction and oxidation Removing oxygen chemically from a substance is called reduction. The industrial production of iron involves reducing iron (III) oxide in a Blast Furnace. Most of the iron (III) oxide is reduced using carbon monoxide gas.

Forging Wikipedia

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die.Forging is often classified according to the temperature at which it is performed cold forging (a type of cold working), warm forging, or hot forging (a type of hot working).For the latter two, the metal is heated, usually

Calculating Reduction on Rings Ask Jim Forging

The grain size reduces upon annealing if the final forging temperatures are proper for the alloy. For example, overheating can occur at only 2,200F for a low-alloy steel if there is little or no reduction. For austenitic stainless, final grain size is controlled almost entirely by the final forging reduction.
