Product Description:
HAYNES® 242®RTW™ filler metal is used for the gas tungsten arc and gas metal arc welding of HAYNES® 242®alloy. The deposited weld metal has low thermal expansion characteristics, good oxidation resistance to 1500°F (815°C) and excellent fabricability. The alloy is used in gas turbine seal rings, containment structures and high-strength fasteners. The RTW™ finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
