The production of steel necessitates iron-based raw materials like iron ore or scrap metal, along with alloying elements to impart specific properties. Coal and limestone also play essential roles in ore-based steel production.

Iron ore

Iron ore is chemically bonded with oxygen and sulfur in compounds, extracted from oxides such as magnetite and hematite. The processing yields dressed ore or pellets for steel production.

Swedish steel production predominantly relies on pellets derived from magnetite ore, offering energy efficiency and high iron content. Scrap steel remains integral to steel production processes.

Scrap metal

Scrap metal is categorized into internal, engineering workshop, and scrap collection types for use in steel production. Charcoal and coke serve as reducing agents during iron production.

Limestone

Limestone acts as a slag former in the iron and steelmaking process. This slag, an active component in metallurgical processes, binds unwanted substances in steel, allowing for control of its composition and enhanced properties.
Further details on slag can be found in the Processes section.

Limestone is a crucial component in iron and steelmaking processes.

Alloying elements

Steel, an iron-based alloy, contains trace amounts of carbon, silicon, and manganese. During production, alloying elements like chromium, nickel, molybdenum, and vanadium are introduced to enhance properties such as corrosion resistance, hardness, wear resistance, and toughness. Ongoing research efforts in Sweden and globally aim to optimize the selection of alloys for specific steel applications.

High-alloy steels, exemplified by stainless steel, feature increased levels of alloying elements. Stainless steel typically comprises 18-20% chromium and 8-10% nickel, referred to as “18/8 steel,” commonly utilized in items like cutlery, pans, and sinks.

When producing crude steel from metal scrap, preference is given to scrap containing the necessary alloying elements. The molten steel is monitored during production, with appropriate alloying elements added to maintain the desired composition.

Diverse metals and ferrous alloys, known as alloying elements, play a critical role in imparting specific properties to steel.
