METHOD OF PRODUCING A PAINTED STEEL SHAFT PRODUCT OF HIGH STRENGTH |
摘要 |
A high-strength product of sheet steel is produced in the press hardening process. A blank is heated to reach austenite structure and hot-stamped in a pair of cooled tools. The product is kept in the tools to rapidly be cooled to harden with the tools as a fixture. The blank has a surface of black oxide before it is shaped and the shaped product is painted directly on the black surface.
