ERNiFeCr-2
UNS N07718
Werkstoff – Nr. 2.4668
AWS A5.14
ERNiFeCr-2 is used for gas-tungsten-arc welding of alloys 718, 706 and X-750. The weld metal is age hardenable and has mechanical properties comparable to those of the base metals.
The filler metal can be used with both the gas metal arc and gas tungsten arc processes.
