The medium carbon low manganese, AISI 1141 carbon steel is a general purpose grade with good machinability and weldability features. The chemical formula of the material usually includes carbon (C) accompanied by manganese (Mn,) phosphorus (P,) sulfur (S,) and iron (Fe,) empowering the creation of readily available structures found in nature. Several features such as carbon content from 0.37% to 0.44%, excellent strength and durability are makes it ideal for wide industrial applications. AISI 1141 has got a close association with the manufacturing of shafts, studs, bolts and the machines components which call for endurance and strength. With that,we can utilize the features of this material by heat-treat operations. The table, chart and PDF detailing the composition, mechanical properties and applications of the material are easily available for academic use by engineers and manufacturing companies to select the most appropriate grade provided by the material.
AISI 1141 is a carbon steel grade characterized by good machinability and weldability, key qualities for the production of complex parts. Usually, its chemical formula comprises carbon, manganese, phosphorus, sulfur, plus other elements which are in traces. Having a carbon content around 0.36-0.44% grade, enables good strength and toughness suitable for variety of industrial applications such as automotive, construction, and sports goods industries. The reason lies in the manganese which contributes to its hardenability, the phosphorus which improve the machinability of cast iron and the sulfur as well. AISI 1141 is a popular material used in manufacturing components like gears, shafts, bolts, and studs which need both high strength and machinability.
