INCO-WELD 725NDUR Filler Metal

 

INCO-WELD 725NDUR Filler Metal is an age hardenable version of INCONEL Filler Metal 625. After post-weld heat treatment it combines the excellent corrosion resistance of INCONEL Filler Metal 625 with higher strength and hardness. oil patch applications require the same temperature range required for age harding INCO-WELD 725NDUR Filler Metal. If post-weld annealing is followed by the aging treatment, even higher strength and hardness values are obtained.

 

The filler metal can be used with both the gas metal arc and gas tungsten arc processes.
