M42 is a molybdenum-series high-speed steel alloy with an additional 8% cobalt. [14] It is widely used in metal manufacturing industries because of its superior red-hardness as compared to more conventional high-speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time ...
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

Maraging blades are superior for foil and épée because crack propagation in maraging steel is 10 times slower than in carbon steel, resulting in less frequent breaking of the blade and fewer injuries. [i] [19] Stainless maraging steel is used in bicycle frames (e.g. Reynolds 953 introduced in 2013) [20] and golf club heads. [21]
A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. [1] Key characteristics of a superalloy include mechanical strength , thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance.
Hexaferrum and epsilon iron (ε-Fe) are synonyms for the hexagonal close-packed (HCP) phase of iron that is stable only at extremely high pressure. A 1964 study at the University of Rochester mixed 99.8% pure α-iron powder with sodium chloride , and pressed a 0.5-mm diameter pellet between the flat faces of two diamond anvils.
The coefficient of thermal expansion of cemented tungsten carbide is found to vary with the amount of cobalt used as a metal binder. For 5.9% cobalt samples, a coefficient of 4.4 μm/m·K was measured, whereas 13% cobalt samples have a coefficient of around 5.0 μm/m·K.
Can be used up to 900 °C. There are many sort of cemented carbides like ones made of tungsten carbide and cobalt or cermets. Cutting ceramic: They are even harder than cemented carbides but have lower toughness. Aluminium oxide and silicon nitride are used. The latter has higher toughness, but can't be used for machining steel, due to very ...
