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.
CPM REX 76 (HSS) [53] is super high-speed steel made by the CPM (Crucible Particle Metallurgy) Process. It is heat treatable to HRC 68–70. Its high carbon, vanadium, and cobalt contents provide abrasion resistance comparable to that of T15 and red hardness superior to that of M42. CPM REX 86 (HSS) [54] is super high-speed steel made by the ...
Cutting tool materials must be harder than the material of the workpiece, even at high temperatures during the process. 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
Steel of about 0.8% C gets as hard as steel with more carbon, but the free iron carbide particles in 1% or 1.25% carbon steel make it hold an edge better. However, the fine edge probably rusts off faster than it wears off, if it is used to cut acidic or salty materials.
HY-80 is prone to the formation of martensite and martensite's peak hardness is dependent on its carbon content. HY-80 is an FCC material that allows carbon to more readily diffuse than in FCC materials such as austenitic stainless steel. Nickel – Adds to toughness and ductility to the HY-80 and is also an austenite stabilizer.
The materials can be tailored to have specific mechanical properties by optimizing the process parameters associated with LPBF. 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 ...
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.
Spring steel is a name given to a wide range of steels [1] used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally low-alloy manganese , medium-carbon steel or high-carbon steel with a very high yield strength .
