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 the same temperature ranges for stress relieving of low alloy steels (such as AISI 4130) as the temperature range required for age hardenable INCO-WELD® 725NDUR Filler Metal. If post-weld annealing is followed by the aging treatment, even higher strength and hardness 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.
