";s:4:"text";s:4683:" (ii) They possess high wear resistance. Compressive yield strength is about 3250 Mpa.Young’s modulus of elasticity of high-speed steel – AISI M2 is 200 GPa.Rockwell hardness of high-speed steel – AISI M2 depends on heat treatment process, but it is approximately 65 HRC.The Rockwell C test is performed with a Brale penetrator (Melting point of high-speed steel – AISI M2 steel is around 1430°C.The thermal conductivity of high-speed steel – AISI M2 is 41 W/(m.K).The heat transfer characteristics of a solid material are measured by a property called the Most materials are very nearly homogeneous, therefore we can usually write U.S. Department of Energy, Material Science. The first alloy that was formally classified as high-speed steel is known by the High speed steels are alloys that gain their properties from a variety of alloying metals added to carbon steel, typically including tungsten and molybdenum, or a combination of the two, often with other alloys as well.The addition of about 10% of tungsten and molybdenum in total maximises efficiently the hardness and toughness of high speed steels and maintains those properties at the high temperatures generated when cutting metals. For structural applications, material properties are crucial and engineers must take them into account.Ultimate tensile strength of high-speed steel – AISI M2 depends on heat treatment process, but it is about 1200 MPa.Yield strength of high-speed steel – AISI M2 depends on heat treatment process, but it is about 1000 MPa. Our Website follows all legal requirements to protect your privacy. Central to the performance of high-speed steels is the hardening response achieved during the heat treatment process. The Metals Society, London, "Tools and dies for industry", 1977 The mention of names of specific companies or products does not imply any intention to infringe their proprietary rights.This website does not use any proprietary data. Alloying Agents in High-speed Steels. Several methods can be used such as foils, pack boronising, plasma spray powders, powder cored strips, inert gas blow feeders, etc.
The synergistic effect of alloying elements and heat treatment produces a tremendous variety of microstructures and properties. High-speed steel, Alloy of steel introduced in 1900. high hardness at temperature up to 550°C. Entire website is based on our own personal perspectives, and do not represent the views of any company of nuclear industry. Main purpose of this project is to help the public learn some interesting and important information about the peaceful uses of nuclear energy. Pure iron is too soft to be used for the purpose of structure, but the addition of small quantities of other elements (carbon, manganese or silicon for instance) greatly increases its mechanical strength.
