08F Steel
08F Steel
08F steel is a brand of boiling steel in Chinese stamping steel plate(GB/T 699)."F" is the first letter of Chinese spelling of "Fei Teng", translated as boiling steel, 08 refers to the value of carbon content is eight ten thousandths; therefore it is called 08F steel.
08F steel characteristics:
08F steel has low strength, good hardness, plasticity and toughness, and 08F steel is easy to deep draw, draw, bend and weld.
08F steel application:
08F steel plate is used as a container for deep drawing and deep drawing, such as enamel products, instrument panels, automobile cab covers, etc. 08F round steel is used for carburizing or cyanide parts with low core strength requirements.

Heat treatment of 08F steel
Normalizing: 930 ℃, holding time ≤30min, air cooling;
Quenching: 930 ° C, holding time ≤ 30min, 70.80 and 85 steel oil-cooled, and the remaining steel water-cooled;
Tempering: 930 ° C, holding time ≤1h.

The difference between 08 steel and 08F steel
08 steel is a very soft low-carbon steel, with very low strength and hardness, and extremely high plasticity and toughness. It has good cold deformability and weldability. The machinability after normalizing is acceptable. The magnetic permeability is high after annealing. Less magnetic, but extremely low hardenability and hardenability.
F in 08F indicates boiling steel, and 08 indicates that the carbon content is 8 / 10,000. This steel is a high-quality boiling steel with similar performance to 08 steel, but with better aging and sensitivity than 08 steel.
