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).
This kind of high-speed steel is used in custom and high-end knives and it's one of the best and most expensive knife steels currently on the market. The level of HRC that can be achieved with a proper heat treatment is 66 HRC. Maxamet [56] is marketed by its manufacturer as a middle-ground between high-speed steel and cemented carbide ...
A range of 1.75% to 2.75% nickel is still used in some shock-resisting and high-strength low-alloy steels (HSLA), such as L6, 4340, and Swedish saw steel, but it is relatively expensive. An example of its use is in the production of jackhammer bits.
Carbon tool steels: They lose their hardness at 200 °C; High speed steels: They lose their hardness at 600 °C, and are widely used in machining. Due to their ability to retain hardness at higher temperature, higher cutting speeds are possible. Cemented carbides: Harder than tool steels, but less tough. Can be used up to 900 °C.
A tungsten carbide tipped (TCT) and high-speed steel (HSS) annular cutter (also known as a "core drill" or "hole saw"). An annular cutter (also called a core drill, core cutter, broach cutter, trepanning drill, hole saw, or cup-type cutter) is a form of core drill used to create holes in metal.
Cold saws use either a solid high-speed steel (HSS) [3] or tungsten carbide-tipped, resharpenable circular saw blade. [4] They are equipped with an electric motor and often a gear reduction unit [5] to reduce the saw blade's rotational speed while maintaining constant torque. This allows the HSS saw blade to feed at a constant rate with a very ...

After other high-speed steels were produced, T1 remained one of the most commonly used commercial high-speed steels for the next century. [ 23 ] [ 24 ] The next year Crucible formed the Pittsburg Crucible Steel Company, purchasing a 423-acre (171 ha) site from Midland Steel on the Ohio River near Pittsburgh for $7.5 million to build a new plant ...
