Key steel, also known as key stock or key bar, is a precision-engineered raw material used to create machine keys that lock rotating components like gears and pulleys onto shafts. It is typically made from medium-carbon steel (such as grade 1045 or EN8) to provide a balance of high strength, durability, and excellent machinability.
