Stick Electrodes Böhler FOX SAS 2-A

Böhler FOX SAS 2-A welding electrodes

• Rutile-coated welding electrode
• Particularly good welding characteristics on DC and AC
• Self-releasing slag
• Clean bead and minimal rework
• For Ti- and Nb-stabilized CrNi steels such as 1.4541 / 321 and 1.4546 / 347

Description: 

Böhler FOX SAS 2-A is a stabilized, core-wire alloyed, austenitic welding electrode with a rutile coating. It was developed specifically for Ti- and Nb-stabilized CrNi steels such as 1.4541 / 321 and 1.4546 / 347. This electrode is characterized by particularly good welding properties in both DC and AC applications. It offers high hot-crack resistance of the weld metal and produces clean beads. The slag is self-releasing, which minimizes rework. The corrosion resistance corresponds to that of 316Ti alloys, and the electrode shows good resistance to pitting. The maximum operating temperature is 400ºC.

Base materials for Böhler FOX SAS 2-A

1.4301 X5CrNi18-10, 1.4306 X2CrNi19-11, 1.4311 X2CrNiN18-9, 1.4312 GX10CrNi18-8, 1.4541 X6CrNiTi18-10, 1.4546 X5CrNiNb18-10, 1.4550 X6CrNiNb18-10, 1.4552 GX5CrNiNb19-11 UNS S30400, S30403, S30453, S32100, S34700 AISI 347, 321, 302, 304, 304L, 304LN

Notes:

It is recommended to limit the heat input to a maximum of 1.5 kJ/mm, and the interpass temperature should not exceed 150ºC. Generally, no heat treatment is required. However, Böhler FOX SAS 2-A can be used for cladding where stress-relief annealing at approximately 590ºC is normally necessary. Such heat treatment can reduce ductility at room temperature. In these cases, Böhler FOX E 347 H may be an alternative. If necessary, redrying can be carried out at 250-300ºC for at least 2 hours.
