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 following properties are required for cutting tool materials: [1] hardness, hot hardness and pressure resistance; bending strength and toughness; inner bonding strength; wear resistance. oxidation resistance; small propensity for diffusion and adhesion; abrasion resistance; edge strength; There is no material that shows all of these ...

High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel. HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather specific mechanical properties.
Category 1 : steel specified by purpose of use and mechanical properties [ edit ] Basic grade designations for category 1 steels consist of a single letter (designating application) then a number signifying the mechanical property (often yield strength) dictated in the standard for that application designation.
ASTM A354 is an ASTM International standard that defines chemical and mechanical properties for alloy steel bolts, screws, studs, and other externally threaded fasteners.It is officially titled: Standard Specification for Quenched and Tempered Alloy Steel Bolts, Studs, and Other Externally Threaded Fasteners.
CPM REX 121, [47] is a new high vanadium cobalt bearing tool steel designed to offer a combination of the highest wear resistance, attainable hardness, and red hardness available in a high-speed steel. [48] CPM REX 20 (HS) [49] is a cobalt-free super high-speed steel made by the CPM process.
A514 is a particular type of high strength steel, which is quenched and tempered alloy steel, with a yield strength of 100,000 psi (100 ksi or approximately 700 MPa). The ArcelorMittal trademarked name is T-1. [1] A514 is primarily used as a structural steel for building construction.
