Applications / Features

Rutile-basic coated stick electrode for

Hardfacing and joining welds on similar and comparable corrosion- and scale-resistant 25% Cr steels (Mo-free).

The weld metal is corrosion-resistant like similar and comparable duplex steels.

Scale-resistant up to 1150°C

(in air and oxidising flue gases).

Highly resistant in sulphurous gases at elevated temperatures.

Applications

Suitable for base materials such as:

1.4340 (G X 40CrNi 27-4),

1.4347 (G X 4CrNiN 26-7),

1.4821 (X 15 CrNiSi 25-4).

heat treatment of the workpiece:

For corrosive service: interpass temperature approx. 250°C.

(In this case, solution annealing followed by quenching of the component is recommended after welding.)
