PURPOSE:To prevent the deterioration of the mechanical properties of the treated part of a Cr-based parent metal even after high temp. treatment such as repair or welding by adding a specified amt. of one or more kinds of metals selected among a group of specified metals to Cr as a principal component to produce a filler metal used. CONSTITUTION:A filler metal is composed of 0.01-10wt.% one or more among Ti, Zr, Hf and Al and the balance essentially Cr. When a parent metal is repaired or welded with the filler metal, a repaired or welded part having mechanical characteristics comparable to those of the parent metal can be obtd. |
