PROBLEM TO BE SOLVED: To provide an inexpensive fire grate having superior corrosion resistance without being excessively cooled in a hot corrosive environment. SOLUTION: This fire grate 10 has a front face coating layer 11, a top face coating layer 12 and a side face coating layer 13 of Ni-group alloy layers on its front face, top face and side face. However, a sliding part of the top face is not coated, and a fire grate part having a concern about corrosion, is coated. COPYRIGHT: (C)2008,JPO&INPIT
