Forming vehicular structural component from sheet steel, involves applying corrosion resistant coating, cold-forming, hot-forming and hardening

摘要

The steel strip or plate is first coated with a metal or metal alloy in a process causing physical-mechanical bonding. Thermal and corrosion resistance is imparted. Then the coated sheet is cold-formed. In the following hot-forming process, it is configured to the final shape and hardened.
