1searchProperties, characteristics and uses of carbon surface structural steelsteel gradePerformance characteristicsExamples of usesOSFHigh quality boiling steel, low strength and hardness, good cold deformation plasticity, deep drawing and good weldability.The composition tends to segregate, and the aging sensitivity is high. Therefore, during cold working, stress-relieving heat treatment or water toughening treatment should be adopted to prevent cold working from breaking to produce thin plates, thin strips, cold deformed materials, cold-drawn steel wires, etc., which can be used as stamping parts, calendered parts, various non-load-bearing covering parts, sleeves, barrels, pipes, gaskets, instrument panels, carburized parts with low core strength requirements, and sulfonitriding parts.0SVery soft low carbon steel, with very low strength and hardness, excellent plasticity and toughness, good cold workability, poor hardenability, and slightly weaker aging sensitivity than 08F, is not suitable for cutting. After annealing, magnetic conductivity can be improved.Production of thin plate, thin strip, cold deformed material, cold drawing, cold stamping, welded parts, surface-mastering parts with low core strength such as clutch discs, thin plate and thin strip products such as barrels, pipes, gaskets, and covered electrode, etc.10F10The strength is slightly higher than that of 0S/0SF steel, which has good plasticity and toughness, is easy to be formed by cold and hot working, and has good machinability after normalizing or cold working, excellent weldability, no temper brittleness, and poor hardenability and hardening capacity.Manufacture parts with low stress and high toughness, such as automobile body, reservoir, deep-drawing utensils, pipes and mats! Sheet, etc., can be used for cold rolling, cold stamping, cold shoveling, cold bending, hot rolling, hot extrusion, hot stamping and other processes, and can also be used as carburized parts and carbonitriding parts with low core strength requirements.15F15The strength, hardness and plasticity are similar to those of 10/10F steel. In order to improve its cutting performance, normalizing or water toughening treatment is needed to improve the hardness appropriately.
