Abstract:
1. A method of attaching together two components comprising the steps of: a) providing a first component; b) providing a second component; c) placing a filler metal between said first component and said second component; said filler metal comprising: from about 0.05% to about 0.1% C; not more than about 1.0% Si; not more than about 0.8% Mn; from about 10.5% to about 13.0% Cr; from about 0.65% to about 4.0% Ni; from about 1.0% to about 1.5% Ti; not more than about 0.5% each of N, S, P, Mo, Nb, Cu, V, or Co; and balance essentially Fe; and d) welding the filler metal to form a weld between said first component and said second component thereby attaching together said components; wherein said weld comprises an amount of martensite sufficient to increase the volume of the weld thereby at least partially offsetting shrinkage of the weld upon cooling.
