High hardness steel

Web4 de jun. de 2024 · High hardness alloy steels include the following types: Chromium Alloy Steels Chromium is principally used as an alloying element to increase corrosion reistance of the metal. It also improves shock resistance, and gives high strength to the alloy without any appreciable loss in ductility. The term hardened steel is often used for a medium or high carbon steel that has been given heat treatment and then quenching followed by tempering. The quenching results in the formation of metastable martensite, the fraction of which is reduced to the desired amount during tempering. This is the most common state for finished articles such as tools and machine parts. In contrast, the sa…
