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.
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 ...
While the foregoing were primarily the materials that a machinist would be cutting, the cutters that the machinist uses must be harder and tougher than the materials to be cut. The materials in the cutters a machinist uses are most commonly high-speed steel, tungsten carbide, ceramics, Borazon, and diamond. [3]

Types of beds include inverted "V" beds, flat beds, and combination "V" and flat beds. "V" and combination beds are used for precision and light duty work, while flat beds are used for heavy duty work. [citation needed] When a lathe is installed, the first step is to level it, which refers to making sure the bed is not twisted or bowed. There ...
Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.
Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material. [ 1 ] [ 2 ] Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the FSW tool.
The basic process, the Thomas-Gilchrist process, remained in use longer, especially in Continental Europe, where iron ores were of high phosphorus content [35] and the open-hearth process was not able to remove all phosphorus; almost all inexpensive construction steel in Germany was produced with this method in the 1950s and 1960s.
