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.
The development of high-strength stainless steel grades, such as "lean duplex" grades, has led to increasing use in structural applications. [6] [7] Thanks to its low reflectivity, stainless steel is used as a roofing material for airports, which prevents pilots from being dazzled.
The American Institute of Steel Construction , Inc. publishes the Steel Construction Manual (Steel construction manual, or SCM), which is currently in its 16th edition. Structural engineers use this manual in analyzing, and designing various steel structures. Some of the chapters of the book are as follows.
Typically national mapping grids have significant distortion and are often not suitable for precise engineering design and construction. For major infrastructure projects specifically designed low distortion engineering grids can be used, an example being the Transport for London London Survey Grid , or tailored snake projections which can be ...
The American Institute of Steel Construction (AISC) is a not-for-profit technical institute and trade association for the use of structural steel in the construction industry of the United States. AISC publishes the Steel Construction Manual, an authoritative volume on steel building structure design that is referenced in all U.S. building codes.
Type 308—used as the filler metal when welding 304. Type 309—better temperature resistance than 304, also sometimes used as filler metal when welding dissimilar steels, along with inconel. Type 310 310S— is a highly alloyed austenitic stainless steel used for high temperature application. The high chromium and nickel content give the ...
The tube-frame design required 40 percent less structural steel than conventional building designs. [97] The buildings used high-strength, load-bearing perimeter steel columns which acted as Vierendeel trusses. [98] [93] Although the columns themselves were lightweight, they were spaced closely together, forming a strong, rigid wall structure.
They are used in cars, trucks, cranes, bridges, roller coasters and other structures that are designed to handle large amounts of stress or need a good strength-to-weight ratio. [2] HSLA steel cross-sections and structures are usually 20 to 30% lighter than a carbon steel with the same strength. [3] [4]
