发明名称 METHOD FOR HOT PRESS FORMING OF COATED STEEL AND HOT PRESS FORMED PRODICTS USING THE SAME
摘要 <p>Disclosed are a hot press forming method and a product formed using the hot press forming method, able to process a plated steel blank under appropriate heat treatment conditions to prevent the volatilization of a plated layer and the formation of oxidized scale, and which divisionally heats the plated steel blank in a secondary heating process to provide different strengths and physical properties to the product. The hot press forming method includes primarily and entirely heating the plated steel material to a predetermined temperature and maintaining the plated steel material at the predetermined temperature, secondarily and rapidly heating at least one portion of the plated steel material after the high temperature maintenance of the plated steel material, and performing a hot press forming and cooling process on the secondarily heated plated steel material.</p>
