Lastifil 809 G

Cored wire for crack resistant joints

Used for joining stainless steel and difficult to weld steels and joining Cr/Ni/Mo steels with low carbon content (C<0.03%).

Very good corrosion resistance.

High strength and creep resistance at high temperatures.

High fluidity. Regular and beautifully formed beads.

Excellent X-ray quality.

Specifications & Usage


Joining stainless steel and difficult to weld steels, Cr-Mo steel, high carbon containing steel, Mo-containing steels.

Joining stainless steel to mild steel.


Remove all traces of dirt from the weld edges.

Weld with a ‘stick-out’ of 15 to 25 mm (0.6-1").

Before depositing a second layer, always remove the slag with a stainless steel brush or grinding disc.

The interpass-temperature in the welding zone has to remain below 200 °C (400 °F): if not, cool down before applying a new layer.

To get a correct wire feed, it is necessary to use the appropriate driving wheels for flux cored wires on the wire feeder.
