SAE 1026 is a low-to-medium-carbon steel used in the annealed, hot-worked, normalized, cold-worked or water-quenched-and-tempered condition for a variety of engineering and construction applications. It combines good workability (hot or cold), good machinability and good weldability. It has relatively high manganese (0.60-0.90%); this provides increased hardenability which is reflected in all uses and gives somewhat increased hardness and strength in the core of carburized parts and in uncarburized applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: CS-60. Producer or source: Carbon steel mills.
