Perforated carbon steel has no specified minimum quantity of any alloying element and
contains only an incidental amount of any element other than
carbon, silicon, manganese, copper, sulphur and phosphorus.
It is the most corrosive and least expensive of the commonly
Carbon steel is either referred to as Hot Rolled, steel that underwent a rolling thickness reduction step while
hot, or Cold Rolled, where the steel is cold reduced to the specified thickness. Cold
rolling elongates the grains of the steel in the direction of
rolling, making the steel hard and brittle. Annealing in a reducing
atmosphere recrystallizes the grains, giving the perforated sheet
steel the ductility needed for its intended use.
Hot Rolled Pickled and Oiled Hot rolled coil or sheet steel that has been descaled of oxide film by
either a chemical method, mechanical method, or a combination of
both and oiled for corrosion protection.
