E81T1-Ni1C Low Alloy Steel Flux Cored Wire


E81T1-Ni1C Low Alloy Steel Flux Cored Wire

The E81T1-Ni1C low alloy steel flux cored wire comes with Titanium slag system.This CO2 welding wire generates flawless bead appearance, low spatter, excellent slag detachability and porosity resistance.

Moreover, this kind of low alloy steel flux cored wire is capable of showing exceptional impact toughness and considerable mechanical properties even in low temperature. Therefore, this heat resistant steel welding consumable has been extensively applied to all position welding for shipbuilding, offshore structures, bridges and storage tanks, etc.
