An intermediate product producer that purchases materials and processes them specifically for a particular project.


The reduction of iron ore to iron pellets that can be loaded into an electric arc furnace with an equal amount of scrap. This process allows producers to bypass the coke oven-blast furnace route to produce hot metal from iron ore.


A condition leading to the eventual fracture of a material due to constant or repeated stresses that exert less pressure than the tensile strength of the material.


The body-centred cubic crystalline phase of iron-based alloys.


Magnetic steels that have a low carbon content and contain chromium as the main alloying element, usually between 13% and 17%. It is the second most widely used steel. Ferretic steels are generally used in automotive trim and exhaust systems, hot water tanks, and interior architectural trim.


Metal products such as ferrochrome, ferromanganese, and ferrosilicon that are commonly used as raw materials to aid various stages in steel making. Certain stages could be deoxidisation, desulphurisation, and strength adding.


A common raw material in stainless steel production. This alloy consists of iron and up to 72% chromium.


Any metal that is primarily composed of iron.


The final condition of the surface after the last phase of production.

Finishing Facilities

These facilities process semi-finished steel into ready-made forms that can be used by others. Some facilities are rolling mills, pickle lines, tandem mills, annealing facilities, and temper mills.

Flat-Rolled Steel

Category of steel that includes shapes such as sheet, strip, and tin plate.


An iron cleaning agent that consists of limestone and lime. These products react with impurities in the metallic pool and float to the top of the liquid iron.


Metal with a maximum width of.005 inches.


Forming a hot or cold metal into a fixed shape by hammering, upsetting, pressing, or rolling.


An accumulation of marine organism deposits on a submerged metal surface. Fouling also refers to the accumulation of normally inorganic deposits on heat exchanger tubing.

Fretting Corrosion

Deterioration at the interface of two contacting surfaces under load which is accelerated by their relative motion.
