ASTM SAE AISI 1018 Carbon Steel Chemical Composition, Mechanical Properties

SAE AISI 1018 steel is one of the commonly used low carbon steels. It is usually used as carburized steel. Since most of the 1018 carbon steel is produced by cold drawing, this cold rolled steel is called C1018 (1018 cold rolled steel). AISI C1018 steel (1018 CRS) has good weldability, surface hardening quality, higher mechanical properties and better machinability. Cold drawing increases tensile strength, yield strength, torsional strength, surface hardness and wear resistance, but reduces ductility. ASTM AISI SAE 1018 hot rolled steel is also known as 1018 HR, and has good toughness, strength, ductility, formability, weldability and workability. Below is material AISI 1018 carbon steel properties and specifications including chemical composition, physical and mechanical properties such as density, thermal expansion coefficient, thermal conductivity, tensile, yield strength and hardness, etc.
