AISI 1080 Carbon Steel Chemical Composition & Properties, Grade, Charts and Document

AISI 1180 is a high-carbon steel that is renowned for razor-sharp strength and toughness. Its chemical composition encompasses approximately 0.75-0.88%cm, 0.60-0.90%Mn, and small amounts of other elements mainly P and S. It is a non-alloyed steel that possesses good hardenability and wear resistance. Heavily alloyed with a specific combination of elements, this 52100 grade of steel is typically put to use in applications requiring high strength, such as springs, blades, and implements for agricultural work, among others. The steel alloys offer such properties such as high tensile strength and hardness, as well as good machinability and weldability when when heat-treated properly. There are several table, charts and documents on hand that cover its mechanical properties, heat treatment processes and recommended usage applications. This is important information as it gives engineers and manufacturers the proper guidance when using AISI 1080 carbon steel in their projects.

AISI 1080 Carbon Steel Chemical Composition And Grade Table

AISI 1080 carbon steel is another alloy whose carbon concentration ranges between 0.75 and 0.88 percent. Besides owning carbon, its composition normally comprises of manganese, phosphorus, sulfur and silicon that are present in very tiny amounts. As a result of high carbon content the steel gains superior strength and hardness, the amazing properties that allow using the material for many industrial applications such as, for example, springs, blades, and machinery parts. As for the grade, AISI 1080 among the carbon steels of the standard type and that have high-quality performance with good weldability in case of proper heat treatment. It points out that it's chemical constituents and grade classifications indicate the varied uses and reliability in different engineering fields.
