Kylmätyöstöteräs

Kylmätyöstöteräs, often translated as cold work steel, refers to a category of tool steels designed for applications involving high wear, abrasion, and deformation at or near room temperature. These steels are characterized by their high hardness, excellent wear resistance, and good toughness, making them suitable for shaping and cutting other materials without significant heat generation.

The primary alloying elements in kylmätyöstöteräs typically include carbon, chromium, tungsten, molybdenum, and vanadium. Carbon contributes to hardness, while the other elements form hard carbides, which are crucial for wear resistance. Chromium enhances hardenability and corrosion resistance. The specific composition varies depending on the intended application and desired properties.

Kylmätyöstöteräs is heat-treated to achieve its optimal properties. This usually involves hardening by heating to a specific temperature and then quenching in oil or air, followed by tempering. Tempering reduces internal stresses and increases toughness while retaining high hardness.

Common applications for kylmätyöstöteräs include the manufacturing of dies, punches, cutting tools, stamping tools, drawing dies, and molds. Its ability to withstand significant stress and abrasion without deforming or losing its sharp edge is essential in these demanding environments. Different grades of kylmätyöstöteräs are available, each offering a unique balance of hardness, toughness, and wear resistance to suit specific industrial needs.
