AISI 1215 is a steel that is resulfurized and rephosphorized; it may therefore be called "leaded" steel because of its excellent machinability. This element is usually found containing elements like carbon, manganese, phosphorus, sulfur, and some other minor components. Featuring the high sulfur content, AISI 1215 thus aids in chip-breaking, and its rapid machinability is very appropriate for high speed machining. With a superior grade of spindle tolerances and surface finish, this type is widely used in a lot of precision parts such as bolts, nuts, screws, shafts, and many others. Its properties consist of easy to weld from, formability, and are relatively strong. AISI 1215 carbon steel is mainly delivered in the cold drawn or turned and polished form of processing.

AISI 1215 is called a free-cutting steel due to some of its wonderful properties such as easy machining, non-distortional welding. In addition, its chemical properties generally contain 0.09% carbon, 0.75-1.05 manganese, 0.04-0.09% sulfur, 0.04-0.09% phosphorus. By optimizing its grooved structure, the material improves its machinability, thus becoming a perfect candidate for high-speed machining tasks. Furthermore, it is very accurate dimensional and has excellent surface finish quality. Alloy 1215 is commonly used where flat sheets, tubes or bars are needed and the tolerances are to be tight. Such are the typical uses in the automobile, electronics or machinery industries. Its pretty high performance and reliability make it the preferred choice in the manufacture of many processes.
