Rutile flux-cored wire of type E309LT1 is primarily intended for surfacing low-alloyed steels and for dissimilar welds between mild steel and CrNi stainless steels. Ferrite measured with FeritScope MP30 14-22 FN. Corrosion resistance is superior to E308L fillers. When used for overlay welding on mild steel a corrosion resistance equivalent to that of 1.4301 / 304 is obtained in the fiirst layer. The wide arc ensures even root and side-wall penetration to prevent lack of fusion. It is designed for all purpose welding and can be used in all positions without changing the parameters, when set up correctly. Due to the fast freezing rutile slag, the weldability is excellent particularly in the vertical-up and overhead positions.
Features
Very good slag detachability
Almost no spatter formation
Applications
Suitable for service temperatures from –75°F to 570°F
The scaling temperature is approximately 1830°F in air
For flat and horizontal welding positions, FOXcore 309L-T0 DG may be preferred.
