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 property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.
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 ...
The correct tool to start a traditionally drilled hole (a hole drilled by a high-speed steel (HSS) twist drill bit) is a spotting drill bit (or a spot drill bit, as they are referenced in the U.S.). The included angle of the spotting drill bit should be the same as, or greater than, the conventional drill bit so that the drill bit will then ...

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).
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.

A common type of micro-alloyed steel is improved-formability HSLA. It has a yield strength up to 80,000 psi (550 MPa) but costs only 24% more than A36 steel (36,000 psi (250 MPa)). One of the disadvantages of this steel is that it is 30 to 40% less ductile.
