In 08F, F means rimmed steel, 08 means carbon content is 8/10000, 08F is the grade of 1006 steel. 08F steel has very low strength and hardness, and extremely high plasticity and toughness. It has good cold deformability and weldability. After normalizing, the machinability is acceptable. After annealing, the magnetic permeability is high, the residual magnetism is less, but the hardenability , Very low hardenability. 08F steel has good plasticity and is mainly used to make cold stamping parts. Manganese plays a role in increasing the elastic strength in steel, so the content can be deviated if it meets the requirements.
08F material is GB GB/T 699-1999 This standard specifies the alloy steel, low alloy steel, alloy steel chemical composition relative to the provisions of the finished steel smelting chemical composition boundary limit allowable deviation, and gives the definition of related terms. GB GB 13237-1991 GB GB/T 13793-1992 GB GB 3206-1982 GB GB/T 711-2008 GB GB 3275-1991 GB GB 699-1988 GB GB 710-1991 GB GB 711-1988 This standard specifies the alloy steel, low alloy steel, alloy steel chemical composition relative to the provisions of the finished steel smelting chemical composition boundary limit allowable deviation, and gives the definition of related terms.
