Karbonverktøystål

Karbonverktøystål is a type of steel alloy primarily composed of iron and carbon, with the carbon content typically ranging from 0.6% to 1.7%. This high carbon content is the defining characteristic that distinguishes it from other steel types and grants it superior hardness and wear resistance when properly heat-treated. Other alloying elements are usually present in small quantities, such as manganese, silicon, chromium, vanadium, and tungsten, which can further enhance properties like toughness, hardenability, and resistance to softening at elevated temperatures.

The primary application for karbonverktøystål is in the manufacturing of tools that require exceptional hardness and the ability to maintain a sharp edge under demanding conditions. This includes a wide array of cutting tools like drills, taps, dies, knives, and chisels. It is also used for forming tools, punching tools, and components subjected to significant wear. The specific composition and heat treatment process are crucial in determining the final properties of the tool, balancing hardness with a degree of toughness to prevent brittleness. While offering excellent performance for many applications, karbonverktøystål can be susceptible to rust due to its lower chromium content compared to stainless steels, requiring protective coatings or careful maintenance.
