HASTELLOY® B-3® RTW™ Filler Metal

Product Description:

HASTELLOY® B-3® RTW filler metal is used for the gas metal 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.
