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 chemical composition: C: 0.05-0.11Si: ≤0.03Mn: 0.25-0.50P: ≤0.035S: ≤0.035Cr: ≤0.10Ni: ≤0.30Cu: ≤0.20 Tensile strength σb (MPa): ≥295 (30 ) Yield strength σs (MPa): ≥175 (18) Elongation δ5 (%): ≥35 Reduction of area ψ (%): ≥60 Hardness: unheated, ≤131HBGB/T699-1999
