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.
It is a martensitic stainless high-speed steel that combines the tempering, hot hardness, and hardness retention characteristics of M50 high-speed steels, with the corrosion and oxidation resistance of Type 440C stainless.

4340 steel is an ultra-high strength steel ... The mechanical properties of 4340 are highly dependent on the heat treatment. 4340 can commonly have yield strengths of ...
Manganese steel Manganese steel has medium length sparks that fork twice before ending. [5] High-speed steel High-speed steel has a faint red spark that sparks at the tip. [5] 300-series stainless steel These sparks are not so dense as the carbon steel sparks, do not fork, and are orange to straw in color. [2] 310-series stainless steel
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 ...
It has been observed that processing parameters such as laser scanning speed, power and the scanning space can have significant effects on the mechanical properties of 300 maraging steel such as tensile strength, microhardness, and impact toughness. Along with the processing parameters, the type of heat treatment subjected to LPBF steels also ...
They are expected to be thermally and chemically more stable than diamond, and harder than c-BN, and would therefore be excellent materials for high speed cutting and polishing of ferrous alloys. These characteristic properties are attributed to the diamond-like structure combined with the sp3 σ-bonds among carbon and the heteroatoms.
