AISI 1108 Carbon Steel Chemical Composition & Properties, Grades, Tables and Document

AISI 1108 is carbon steel with medium carbon content which contains mostly iron, carbon, manganese, and silicon (as alloy). Chemical composition of cement normally have a limestone disposition which must have a limestone variety to secrete carbon content from 0.55% to 0.65%, manganese (Mn) as between 0.60% and 0.90% and silicon (Si) silk in their chemical composition which must be between 0.15% and 0.35%. It provides a nice machinability by means of which one can achieve a wide range of technologies in motor industries, engineering, and constructions. By blending in the criteria of right heat treatment, AISI 1108 can reach the target mechanical properties, such as high tensile strength, toughness and the wear resistance. Tables and documents with its grades, properties, and composition are sine qua non for the engineers and producers who use this multifaceted carbon steel alloy.

AISI 1108 Carbon Steel Chemical Composition And Grade Table

AISI 1108 is a carbon steel which is recognized by its good machining and welding abilities. The list of its chemical composition, on the other hand, usually contains, carbon, manganese, phosphorus, sulfur, and a few other traces elements. Being a carbon with a range of carbon content from 0.08% to 0.15% AISI 1108 still has good strength and toughness properties useful for different areas of industrial applications. This grade is frequently used in the components that require accuracy and the mechanisms of piercing or milling such as shafts, gears, and bolts. The chemical constitution and its qualities make it affordable for a company that is seeking a compromise between performance, cost-effectiveness, and ease of integration.
