FERRITE-BASED STAINLESS STEEL HAVING IMPROVED HEAT RADIATION PROPERTY AND PROCESSABILITY AND METHOD FOR PREPARING SAME

Abstract:

Provided are a ferrite-based stainless steel having improved heat radiation property and processability and method for preparing same. A ferritic stainless steel according to an embodiment of the disclosure, includes, in % by weight, carbon (C): 0.0005 to 0.02%, nitrogen (N): 0.005 to 0.02%, chromium (Cr): 10.0 to 17.0%, titanium (Ti): 0.02 to 0.30%, niobium (Nb): 0.10 to 0.60%, and the remainder of iron (Fe) and other inevitable impurities, and the ferritic stainless steel is plated with aluminum (Al) having a thickness of 5 to 50 .mu.m. Therefore, heat dissipation and workability of ferritic stainless steel may be improved by controlling ferritic stainless steel alloy composition, aluminum (Al) thickness and manufacturing method.
