SAE 1045 Steel: Composition and Uses
AISI 1045 steel plate is one kind of high carbon steel. 1045 is suitable for shafts studs, keys, available as rolled or normalised. Supplied as square bar, or round bar or flat. 1045 steel plate is excellent in weldability, machinability, and they can be subjected to various heat treatments. SAE 1045 Steel is one of the commonly used carbon steels with an average carbon content of 0.45%, medium tensile properties, good strength, toughness and wear resistance. It can be treated by annealing, flame treatment or induction hardening. C1045 is also known as 1045 cold rolled steel, and 1045 hot rolled steel is known as 1045 HR. It matches its long-term durability and basic flexibility. American material grades like SAE, AISI and ASTM represent the three major American associations, namely the Society of Automotive Engineers (SAE), the American Iron and Steel Institute (AISI), and the American Society for Testing and Materials (ASTM). SAE 1045, AISI 1045, and ASTM 1045 are just dif...
