AISI 1211 carbon steel sometimes referred to as free-machining steel, has low carbon content which imparts it's superior machinability and ease of arc welding. A chemical composition of the average steel is generally around 0.13-0.18% of carbon, approximately 0.60-0.90% of manganese, 0.040% of phosphorus and 0.050% of sulfur. AISI 1211 features its uniqueness. It has a carbon level controlled and so it is easily cold-worked or formed into various shapes. Furthermore, 3D printing is employed in many sectors which calls for the production of very detailed parts or components where precise machining is obligatory. This grade is rarely utilized in the automotive, machinery, and construction industries. The main reason why the AISI 1211 is preferred by most engineers and manufacturers is its ability to achieve a fairly good balance between cost, ease of work with the material and its performance. Detailed information such as that, (properties, grades, and chemical composition) can be easily accessible from creditable sources on tables, charts or even in PDF documents.
AISI 1211 carbon steel is a readily machinable grade acknowledged for its exceptional weldability and fair formability. A chemical composition chart of 0.09% to 0.15% of carbon, 0.60%-0.90% of manganese, phosphorus max at 0.040%, and sulfur max at 0.050%. Given a tensile strength of 370 MPa (53.6 ksi) and a yield strength of around 260 MPa (37.7 ksi), AISI 1211 is implemented in many different industrial applications such as gear wheel, shaft, bolts or studs because of its balanced properties and cost effectiveness.
