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 ...
High-speed steel, a subset of tool steels Home Subscriber Server , a mobile subscriber database, part of the IMS framework Hollow structural section , a type of metal profile
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 ...
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 The earlier use of rivets is being superseded by improvements in welding and component fabrication ...
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
A514 is primarily used as a structural steel for building construction. A517 is a closely related alloy that is used for the production of high-strength pressure vessels . This is a standard set by the standards organization ASTM International , a voluntary standards development organization that sets technical standards for materials, products ...
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 ...
Machining of metals was greatly enhanced with high-speed steel and later very hard materials such as tungsten carbide for cutting edges. [28] Fabrication using steel components was aided by the development of electric welding and stamped steel parts, both which appeared in industry in about 1890.
