AISI 8660 Alloy Steel Chemical Composition, Grade, Chart and Online Pdf
AISI 8660 is an amazingly low-alloy steel with extremely high strength and toughness capabilities. It is commonly made of carbon, manganese, vanadium, silicon, molybdenum, chromium and nickel which make it standout among the rest in its usage in multiple functionality. Specifically, the AISI 8660 grade and corresponding AISI standards are widely used in manufacturing parts for critical components such as gears, shafts, and axles in various industries like automotive, aerospace and others. The engineers, metallurgists, and numerous other professionals repeatedly check comprehensive charts and online PDFs with the metal’s composition, properties, as well as heat treatment guides so that they can be sure that the metal is used in the most useful way and lasts for the longest time in the projects. It is necessary to know the materials chemical composition and its corresponding grades in order to make selections that meet the defined engineering needs correctly.
AISI 8660 Alloy Steel Chemical Composition And Grade Table
AISI 8660 is a low-alloy steel highly prized for its superior strength and hardness properties would be suitable for a lot of industrial applications. The chemical make up is mainly carbon, manganese, chromium, molybdenum, and silicon in which most of it represents carbon element. This low competitor carbon content provides better hardenability and wear resistance properties on average. As well as that, different alloying elements, such as chromium and molybdenum, are involved in impressive tensile strength and enhancement in overall performance. AISI 8660 belongs to the medium carbon alloy steels category, satisfying a good balance between hardness, strength, and machinability.
