Although molybdenum-rich high-speed steels such as AISI M1 had seen some use since the 1930s, it was the material shortages and high costs caused by WWII that spurred development of less expensive alloys substituting molybdenum for tungsten. The advances in molybdenum-based high speed steel during this period put them on par with, and in ...

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).
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 ...
Modern track typically uses hot-rolled steel with a profile of an asymmetrical rounded I-beam. [16] Unlike some other uses of iron and steel, railway rails are subject to very high stresses and have to be made of very high-quality steel alloy. It took many decades to improve the quality of the materials, including the change from iron to steel.
HSSE tool steel, a type of high-speed steel (HSS) with cobalt-alloy used as a cutting tool material, see High-speed steel#Cobalt High Speed Steels (HSS) Health, safety, security and the environment, a term used in the petroleum industry or as a department of bigger firms, for the general issue see Environment, health and safety
High-carbon steel (HCS) is used for softer materials such as wood, laminated particle board, and plastics due to its flexibility. [citation needed] High-speed steel (HSS) withstands higher temperatures and can cut many types of metals. [citation needed] Bi-Metal (BIM) blades contain a combination of high-carbon steel and high-speed steel. The ...
Its use declined markedly during the second half of the 20th century, [16] but it still retains important uses in industry and construction, and in artisan crafts such as jewellery, medieval armouring and metal couture in the early 21st century. The earlier use of rivets is being superseded by improvements in welding and component fabrication ...
