AISI 1144 carbon steel, which is commonly called stress-proof steel, has the advantage of machineability and weldability that are the best from the meshes. The substance is made up majorly carbons, manganese, phosphate, sulfur and the traces of other elements. Manganese with C 0.40 to 0.48, Si up to 0.48, P up to 0.04 and S up to 0.24 result in acombo of exceptional tensile strength and high-wear resistance. It is prepared in a range between 104 and 107 pound-force per square inch and used in industrial applications where extended strength and firmness are vital, among them are shafts, axles, bolts, and studs. It contains information more than its composition and mechanical properties that may be used as a reference to engineers and manufacturers, assisting them to choose material that is right for their projects. Through comprehensible table, chart and documentation, every relevant detail is included to provide you with a strong overview of its characteristics and uses.
AISI 1144 is a carbon steel, which is recognized for its high strength, machinability and wearing resistance. Usually, its constitution contains the main elements of carbon, manganese, sulfur, and phosphorus with traces of the rest (mostly nickel and iron). In the table of grades, we specify different levels for each of the constituents which guarantee accurate properties for future production. This alloy contains 0.40-0.48% of carbon, 1.35-1.65% of manganese and 0.24-0.33% of sulfur and its properties are characterized by excellent machinability and good mechanical properties suitable for various industrial applications, such as shafts, gears, bolts and studs.
