Method for manufacturing warm pressed-formed members
The invention provides methods for manufacturing warm press-formed members which can ensure post-coating corrosion resistance. A method for manufacturing warm press-formed members includes heating a steel sheet to a temperature in the range from 200 to 800° C. and warm press-forming the steel sheet at a temperature in the above range of temperatures, the steel sheet having a Zn—Ni alloy coating layer on its surface, the coating layer including 10 to 25 mass % Ni and the balance being Zn and inevitable impurities and having a coating weight of 10 to 90 g/m2.
