"Tungsten-based high-speed tool steel" is a tool material used for high-quality cutting tools that are insufficient even with alloy steel. It is widely used as cutting tools and is an important material with extensive applications, including lathes, drills, milling cutters, hobs, broaches, dies, and other tools. The representative type of W (tungsten) steel is "SKH2," which is the basic form known as "18-4-1" (18% W - 4% Cr - 1% V). 【Features】 ■ Primarily composed of W, it excels in hardness and wear resistance. ■ Those containing Co can perform high-speed heavy cutting. *For more details, please refer to the PDF document or feel free to contact us.

The "Molybdenum-based high-speed tool steel" is a tool material that has a low price for steel and a small specific gravity. It has advantages such as high toughness and suitability for interrupted cutting, making it widely adopted in high-speed tool networks. Compared to W (tungsten), it exhibits sufficient effectiveness with about half the weight percentage of the additive due to its atomic weight relationship. 【Features】 ■ Although it has lower high-temperature hardness compared to W-based materials, it is cheaper. ■ It has a low hardening temperature and good thermal conductivity, making heat treatment easy. ■ It has high toughness. *For more details, please refer to the PDF document or feel free to contact us.

The "Cutting Alloy Tool Steel" is a tool material suitable for lathe tools, cold drawn dies, circular saws, and band saws, based on a carbon matrix containing 0.75 to 1.50% C (carbon). It has a relatively high carbon content, and chromium (Cr) and tungsten (W) are added, although nickel (Ni) and vanadium (V) may also be included. This enhances hardness, wear resistance, and cutting performance. [Features] - Base of carbon matrix containing 0.75 to 1.50% C (carbon) - Cr improves hardenability - Ni enhances toughness as it does not form carbides *For more details, please refer to the PDF document or feel free to contact us.

The "Cold Work Tool Steel" is a material used for tools that require wear resistance, such as gauges, press molds, and screw-cutting dies. Typical examples include the so-called die steels like SKD1, SKD11, SKD12, and SKD2, which are high-carbon chromium alloys. They primarily enhance wear resistance by dispersing a large amount of chromium carbide. Due to the high chromium content, they have significant self-hardening properties and can be adequately hardened through air cooling. 【Features】 ■ Minimal deformation and aging deterioration after heat treatment ■ Used for applications requiring wear resistance *For more details, please refer to the PDF document or feel free to contact us.
