HAYNES® 718 RTW™ Filler Metal

Product Description:

HAYNES® 718 RTW™ filler metal is used for the gas metal arc and gas tungsten arc welding of alloys X-750 and 718. Alloy 718 is and age-hardenable alloy with excellent strength to 1200°F (650°C). The alloy is used extensively in gas turbine components and gas turbine repairs. In addition, the alloy can be used for cladding and overlay of parts in the oil and gas industry. The RTW™ filler metal finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
