alumiiniteräksen
Alumiiniteräs, often referred to as aluminum-killed steel, is a type of steel that has undergone a specific deoxidation process during its production. This process involves adding aluminum to the molten steel before casting. Aluminum acts as a strong deoxidizer, reacting with dissolved oxygen to form aluminum oxide (Al2O3). This oxide then floats to the surface of the molten steel as slag, effectively removing oxygen from the metal.
The primary benefit of this aluminum addition is the control it exerts over the steel's final microstructure,
This refined structure contributes to improved ductility, toughness, and surface finish of the steel. Alumiiniteräs is
