HAYNES® M413 RTW™ Filler Metal

Product Description:

HAYNES® M413 RTW filler metal is used for the gas metal, gas tungsten and submerged arc welding of alloy 450 and other copper-nickel alloys. M413 has excellent resistance to sea water corrosion and can be used in marine environments where corrosion resistance is needed. The alloy can be used for the overlay and cladding of steels if a butter later of ERNi-1 is first applied. The RTW finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
