BÖHLER FOX 2.5 Ni伯乐焊条

BÖHLER FOX 2.5 Ni伯乐焊条

Description
Ni-alloyed basic coated electrode for unalloyed and Ni-alloyed fine grained construction steels.
Tough, crack resistant weld deposit. Low temperature toughness to -80 °C.
Good weldability in all position except vertical down. Very low hydrogen content. ( according
AWS condition HD ≤ 4 ml/100 g weld metal )
Preheat 100 - 150 °C on wall thickness > 15 mm, interpass temperature max. 150 °C. Post weld
heat treatment if necessary only as required by the base metal.
