kolstål

Kolstål is a type of steel characterized by its high carbon content, typically ranging from 0.6% to 1.25% by weight. This high carbon concentration significantly influences its properties, making it harder and stronger than low-carbon steels. However, this also makes it more brittle. Kolstål is known for its ability to hold a sharp edge, making it a popular choice for tools such as knives, chisels, and saws. It also finds application in springs and other components where high tensile strength and wear resistance are required. A key characteristic of kolstål is its response to heat treatment. It can be hardened through quenching and tempering processes, allowing for a wide range of mechanical properties to be achieved depending on the specific heat treatment applied. Untreated, kolstål is susceptible to rust and corrosion due to its iron and carbon composition. Therefore, many kolstål items require protective coatings or regular maintenance to prevent degradation. Its ease of sharpening and its robust nature, when properly cared for, have ensured its continued relevance in various industries and crafts.
