Böhler Fox A 7-A

Rutile basic coated austenitic electrode of E Z 18 9 MnMo R / E307-16 (mod.) type for welding and cladding in all positions except vertical down. Versatile electrode for numerous applications – welding of "hard-to-weld" steels, dissimilar welding as well as repair and maintenance. For tough buffer and intermediate layers for cladding of rails and switches, valve seats and in hydropower plants.
The weld metal offers exceptionally high ductility and elongation together with outstanding crack resistance. Good resistance to embrittlement when operating at service temperatures up to 650ºC. The weld metal work hardens and offers good resistance to cavitation. The weld metal is resistant to scaling up to 850ºC, but at temperatures above 500ºC there is not suffi cient resistance to sulfurous combustion gases. The weld deposit offers high ductility, elongation and resistance to hot cracking, also after high dilution of "hard-to-weld" steels.
Designed for fi rst class weld seams and easy handling on AC or DC. Ferrite according to WRC 92 is 4 – 8 FN.
