HASTELLOY® B-3® RTW™ Filler Metal
HASTELLOY® B-3® RTW™ Filler Metal is used for the gas metal arc and gas tungsten arc welding of B-3® alloy. The alloy has outstanding resistance to hydrochloric and sulfuric acids in the as-welded condition and excellent thermal stability. B-3® is a great candidate for overlay and cladding where resistance to hydrochloric and sulfuric acids is needed. The RTW™ filler metal finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
