HAYNES® 25 RTW™ Filler Metal

Product Description:

HAYNES® 25 RTW™ filler metal is used for the gas metal arc and gas tungsten arc welding of HAYNES® 25 alloy. The deposited weld metal has excellent strength, good oxidation resistance to 1800°F (980°C), very good sulfidation resistance, and relatively good resistance to wear and galling. The RTW™ finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
