koldstål

Koldstål is a term used in Scandinavian languages, notably Swedish and Norwegian, to describe a type of steel characterized by its low carbon content, typically below 0.02%. This designation distinguishes it from other steel types where carbon content is a more significant alloying element. The term "koldstål" literally translates to "cold steel" in English, which might allude to its properties or processing at lower temperatures compared to steels that undergo significant heat treatment.

The properties of koldstål are largely influenced by its extremely low carbon content. This results in a material that is very soft, highly ductile, and possesses excellent weldability. It is not typically used for applications requiring high strength or hardness, as these properties are primarily derived from carbon in steel. Instead, koldstål finds utility in specific manufacturing processes where its malleability and ease of fabrication are advantageous.

Common applications for koldstål include the production of thin sheet metal for consumer goods, certain types of wire, and components that require extensive forming or deep drawing. Its ability to be shaped without fracturing is a key attribute. In some contexts, koldstål might also refer to steel that has been processed or finished at low temperatures, although the primary definition relates to its chemical composition. The precise metallurgical definition and its common uses can vary slightly depending on regional industrial practices and historical context.
