2. High-speed steel - Wikipedia

   en.wikipedia.org/wiki/High-speed_steel

   Wrought iron. 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.

3. High-speed rail - Wikipedia

   en.wikipedia.org/wiki/High-speed_rail

   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 ...

   en.wikipedia.org/wiki/High-speed_rail_in_China

   The high-speed rail (HSR) network in the People's Republic of China (PRC) is the world's longest and most extensively used – with a total length of 46,000 kilometres (29,000 mi) in the middle of 2024. [1][2][3] The HSR network encompasses newly built rail lines with a design speed of 200–380 km/h (120–240 mph). [4]

6. Maraging steel - Wikipedia

   en.wikipedia.org/wiki/Maraging_steel

   Maraging steels (a portmanteau of "martensitic" and "aging") are steels that are known for possessing superior strength and toughness without losing ductility. Aging refers to the extended heat-treatment process. These steels are a special class of very-low- carbon ultra-high-strength steels that derive their strength not from carbon, but from ...
