BÖHLER FOX CN 18/11不锈钢焊条

BÖHLER FOX CN 18/11不锈钢焊条

Description
Basic coated, core wire alloyed electrode with controlled delta ferrite content (3-8 FN) for aus-
tenitic CrNi steels with increased carbon contents (e.g. 1.4948 / 304H), in the boiler, reactor and
turbine fabrication. Approved in long-term condition up to +700 °C service temperature (300 °C
in the case of wet corrosion). Resistant to hot cracking, scaling and corrosion. Excellent
weldability in all positions except vertical down. Also suitable for German material no. 1.4551
and no. 1.4550, which are approved for temperatures up to +550 °C.
