High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high- carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness).

Cobalt steel is a type of high-speed alloy steel used primarily for cutting tools. Introduced to manufacturers in 1900, high-speed steel, containing a mixture of tungsten, chromium, and trace amounts of carbon, enabled manufacturers to double or even triple their production.

Oct 28, 2023 · CoS steel is a high carbon cobalt special stainless steel produced by the Japanese Takefu steel company. It is referred to as Cobalt special steel due to the high amount of Cobalt in its alloy composition.

M42 is a molybdenum series high-speed steel alloy with an additional 8 or 10 percent cobalt. It is widely used in metal manufacturing industries because of its superior red hardness as compared to more conventional high-speed steels.

Also known as cobalt steel, this M42 tool steel maintains its hardness in high-speed cutting applications that generate intense heat. Use it to make tools for cutting extremely hard materials. For technical drawings and 3-D models, click on a part number.

High speed steel alloys with cobalt are more modern alloys than molybdenum alloys. These improved alloys (especially M42) add to the characteristics that users love about HSS and simply make them better.

Cobalt is used in many different alloy applications including wear-resistant alloys, superalloys, powder metallurgy, and hard metal. Cobalt gives these alloys increased resistance to wear, corrosion, and heat, proving them with a longer service life and enhancing reliability.
