Document Type and Number:
WIPO Patent Application WO/2023/093111
Kind Code:
A1
Abstract:
The present invention relates to the technical field of metal processing, and in particular to high Cr-Si alloyed coating-free hot forming steel and a hot rolling preparation method therefor. For the problems existing in the prior art that a steel plate for hot forming can be prepared only by adding cold rolling and can be subjected to hot forming only by using a coating, the present invention provides low-cost high Cr-Si alloyed coating-free hot forming steel, and provides the hot rolling preparation method for the hot forming steel. The hot forming steel preparation method of the present invention is simple in process, low in cost and wide in process window, and the prepared hot forming steel is uniform in structure and excellent in mechanical property and high-temperature oxidation resistance.
