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).
CPM REX T15(HSS) [55] is super high-speed steel made by the CPM process. It is a tungsten type high speed containing high vanadium for excellent abrasion resistance, and cobalt for good red hardness, and is used for cutting difficult-to-machine materials where high frictional heating is encountered.

Steel of about 0.8% C gets as hard as steel with more carbon, but the free iron carbide particles in 1% or 1.25% carbon steel make it hold an edge better. However, the fine edge probably rusts off faster than it wears off, if it is used to cut acidic or salty materials.

The Llinars Bridge this bridge is the first steel structure in the high-speed railway (HSR) joining Barcelona and the French Border. The 1,883-foot-long (574 m) Llinars HSR bridge comprises two parts: a 1,008-foot-long (307 m) composite steel–concrete structure crossing Autopista AP-7, and a continuous prestressed concrete bridge crossing the Mogent River with a maximum span of 157 feet (48 m).
High-speed rail (HSR) is a type of rail transport network utilizing trains that run significantly faster than those of traditional rail, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above 250 km/h (155 mph) or upgraded lines ...
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.
Mushet steel was primarily used in machine tools due to its ability to retain its hardness at high temperatures. In 1894, Frederick Winslow Taylor conducted machining comparison tests between Mushet steel and high carbon tool steel. He found that it could cut 41 to 47% faster on hard tire steel forgings and approximately 90% faster on mild steels.
