08F is a type of boiling steel used in stamping steel plates (referred to as 08F in China, CR1 internationally, SPCC in Japan, St12 in Germany, and Br in the former Soviet Union)
F in 08F refers to boiling steel; 08 refers to a carbon content of 0.8 parts per ten thousand;
Characteristics: Low strength, good hardness, plasticity, and toughness, easy to deep draw, stretch, bend, and weld.
Usage: Steel plates are used as containers for deep stamping and drawing, such as enamel products, instrument panels, car cab covers, etc. Round steel is used for carburizing or cyanide parts with low core strength requirements.

Silicon (Si) ≤ 0.03,
Phosphorus (P) ≤ 0.035,
Sulfur (S) ≤ 0.035,
Copper (Cu) ≤ 0.20
