Product Description

NSC-035102TTWR

NS-102 CopperFree™ is a low alloy, high strength solid filler metal containing 0.5% molybdenum to maintain hardness and strength following post weld heat treatment. The manganese and silicon assist in producing a smooth, uniform weld bead and help minimize spatter.

APPLICATIONS

ASTM A182, A217, A234 and A335 high temperature pipe, fittings, flanges and valves and A336 pressure vessel forgings

Applications needing strength after post weld heat treatment

All metal transfer modes of GMAW

Robotic, mechanized or semi-automatic welding

Best results when using 95-98% Argon/Balance Oxygen shielding
