FOR WELDING MARTENSITIC STAINLESS STEELS WHEN IMPROVED CORROSION RESISTANCE AND SUB-ZERO TOUGHNESS IS REQUIRED
NSN-410NiMo
CLASSIFICATION
AWS A5.4 E410NiMo-26 | EN ISO 3581-A E 13 4 R
PRODUCT DESCRIPTION
A special rutile based flux with a positive ratio of chemically basic minerals to acid minerals that contains all the major alloying elements is extruded onto a high purity ferritic wire. The use of balanced silicates ensures both strength of coating and resistance to moisture absorption
WELDING FEATURES OF THE ELECTRODE
The arc stability is excellent on both AC and DC+ as is the electrodes ability for initial arc strike and re-striking. Spatter is minimal and the slag is readily detachable leaving smooth evenly rippled seams of pleasing appearance. Metal recovery is some 130% with respect to weight of the core wire. Pre-heat and interpass temperature should be 200 ºC max.
