Leikkuuterästä

Leikkuuterästä, often translated as cutting steel or tool steel, refers to a group of carbon tool steels known for their exceptional hardness and wear resistance. These steels are specifically designed to withstand the stresses and temperatures involved in cutting and shaping other materials. The high carbon content, typically ranging from 0.6% to 2.0%, is a key factor in achieving the desired hardness, as it allows for the formation of hard carbides within the steel matrix.

The properties of leikkuuterästä can be further enhanced through heat treatment processes such as hardening and tempering. Hardening involves heating the steel to a critical temperature and then rapidly cooling it, usually in a quenching medium, to create a martensitic structure. Tempering, a subsequent process, involves reheating the hardened steel to a lower temperature to reduce brittleness and improve toughness, while still maintaining a high level of hardness.

Leikkuuterästä finds widespread application in manufacturing tools that require precise and durable cutting edges. This includes items like knives, chisels, punches, dies, and various types of cutting blades used in machining and metalworking. The specific composition and heat treatment of leikkuuterästä can be tailored to optimize its performance for different cutting tasks and materials, balancing hardness, toughness, and wear resistance. Due to their specialized nature, they are a critical component in many industrial processes where efficiency and precision are paramount.
