Alloy 3 Stellite Chemical Composition Properties, Grade, Charts and PDF Online
3 Stellite is molybdenum (Mo) containing cobalt-based alloy in which the properties of resistance to wear and corrosion are the exception. Its applications prevail in industrial operations which are demanding and harsh. It is made mainly of cobalt, chromium, and tungsten, and for this reason it is the hardest unbreakable metal in the world. The incorporation of molybdenum leads to greater strength and heat resistance providing the best material for high temperature areas. Alloy 3 Stellite is extensively applied in cutting tools, seats of valves and components fulfilling such role under rotatory and sliding abrasion operations. a Grade 3 classification implied premium quality and dependability, and USACOG fulfilled hard standards of the industry. Charts, tables and PDF resources of all detailed data are available online providing complete info about its components, specific features, and application procedures which could help engineers and manufacturers to optimize performance and durability in their field of work.
Alloy 3 Stellite Chemical Composition And Grade Table
Both Stellite 3 and Stellite family in general are famous due to their super high level of wear resistance, toughness as well as corrosion resistance through the most severe conditions. Based mainly on cobalt, chromium and tungsten, with between 55% and 65% Co, from 25% to 32% Cr, and 9-12% W, several small content of carbon, silicon and iron are added to obtain finer properties. This composition typically is applied to the heat and wear resistance requiring products e.g cutting tools, valves and the aerospace components. Grade tables outline in full degree the exact material content for maximum functioning.
