A Chemically Basic Flux coated Nickel Based Alloy High in Both Cr and Mo.
CLASSIFICATION : AWS/SFA-5.11: E NiCr Mo-6
BS EN ISO 14172
BS EN ISO 14172
CHARACTERISTICS :
Basic coated special welding electrode with high Nickel, Chromium and Molybdenum core wire. The electrode suitable for use on DC+ and welding with smooth Arc and Great arc stability and thus easy control of weld pool with good slag detachability.
APPLICATION :
- As the weld metal has given excellent cryogenic properties, both toughness and lateral expansion,
- Cryogenic vessels & pipe work of 9% Ni steel for temperatures down to -196°C.
- Suitable for ASTM A353, A533, UNS k81340 and K71340.
- Also suitable for 5% Nickel steel including ASTM A645 and A352 LC4 (cast.)
RE-DRY CONDITION : Re-Dry the electrode at 350°C for 2 hour before use.
