Heat Treatment of High-Speed Steels :: Total Materia ArticleThe high hardening temperatures employed for high-speed steels are conducive to rapid grain growth and hence the holding time must be carefully controlled. The hardening temperature must also be accommodated to the original dimensions of the steel stock used for the tool, since as the stock dimension increases the amount of carbide segregation increases which, in turn, lowers the temperature of incipient fusion.

What is Hardness of High-speed Steel - Definition hardening high speed steel

High-speed steel is superior to the older high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness). High-speed steels are complex iron-base alloys of carbon, chromium, vanadium, molybdenum, or tungsten, or combinations there of.

Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). The minor load establishes the zero position. The major load is applied, then reSee more on nuclear-power.net

High-speed steel containing 10% Co has a somewhat reduced hardenability and in order to arrive at maximum hardness by means of air cooling, light sections only (less than 30 mm in diameter) can be treated in this way. Having been quenched from a normal hardening temperature, high-speed steels contain between 20% and 40% retained austenite.Hardening, Sharpening And Tempering ToolsJun 16, 2011 · Hardening, Sharpening And Tempering Tools. Cutting tools used in wood and metalwork are generally made from medium to high carbon steel (cast steel), which is hardened and temperedduring manufacture of the tools. Mild steel, which contains very little carbon, cannot be hardened and is not used for tools. The purpose of hardening is to enable the tool to resist wear and make it hard enough to cut other materials; tempering is carried out after hardening Hardening of Steel: Objectives and Components | MetallurgyThese steels are mostly alloy tool steels such as, high speed steel having Fe-0.75% C, 18% W, 4% Cr, 1% V.
