Document Type and Number:
WIPO Patent Application WO/2019/045188
Kind Code:
A1
Abstract:
Disclosed are a ferrite-based stainless steel and a method for preparing the same. A ferrite-based stainless steel according to an embodiment of the present invention comprises, in wt%, 0.0005-0.02% of carbon (C), 0.005-0.02% of nitrogen (N), 10.0-17.0% of chromium (Cr), 0.02-0.30% of titanium (Ti), 0.10-0.60% of niobium (Nb), and the remainder iron (Fe) and other inevitable impurities, wherein aluminum (Al) is plated with a thickness of 5-50 μm on the stainless steel. Therefore, the heat radiation property and processability of the ferrite-based stainless steel can be improved by controlling the alloy components, aluminum (Al) plating thickness, and preparation method of the ferrite-based stainless steel.
