08F is a steel stamping with a grade of steel in boiling (China says 08F, International said CR1, Japan said SPCC, Germany with St12, the former Soviet Union with Br),

Features: low intensity and hardness, ductility, toughness, and easy deep-drawing, drawing, bending and welding.

Uses: steel for deep drawing and deep drawing of the container, such as enamel products, instrument panels, covers and other vehicle cab. Ministry of strength for less demanding round the heart of carburizing or cyanide parts.
