AISI 1137 Carbon Steel Chemical Composition Properties, Grades, Tables and Document

AISI 1137 Carbon Steel is specified as a mid-carbon steel featuring good machinability and toughness. The chemical composition of this steel is mainly made up of carbon (C) ranging between 0.35% and 0.40%, manganese (Mn) is 0.60% to 0.90%, phosphorus (P) is max 0.040%, and sulfur (S) is max 0.050%. Another well-known type of steel is this grade steel because it is often used in many applications such as gears, shafts, bolts, and studs and witching property of being strong and machinable. Amazonian irradiated steel alloy (AISI 1137) is according to the American Iron and Steel Institute (AISI) specifications, and it’s available in various grades and forms. The inventory both mechanical characteristics and heating of steel is given in tables, chart and documents, which include information about grades for specific industrial purposes.

AISI 1137 Carbon Steel Chemical Composition And Grade Table

AISI 1137 carbon steel is a non-alloy steel row, fertilizer, machine parts, cannons, and railroad tracks play a vital role in advancing modernity and industrialization. The carbon atom is among the most frequent constituents of steel alongside the manganese, phosphorus, sulphur, and iron atoms. This class of steel has good machinability and weldability; therefore, it is inclusive for most of the production processes in manufacture or construction. Usage examples such as shafts, bolts, studs and machinery components are among major ones. Its composition and properties will always meet the AISI (American Iron and Steel Institute) standards, which ensures its uniform quality and effectiveness in the industrial settings.
