GRITINOX 347

IDENTIFICATION
GRITINOX 347 E347-17

CLASSIFICATION
AWS/SFA 5.4 E347-17 BS 2926 E19.9.NbR
DIN 8556 E199NbR26

DESCRIPTION 
A rutile flux coated AC/DC electrode designed for welding of stabilised stainless steel grades 347 and 321. Operability is excellent with a low spatter arc, producing a smooth weld bead surface and self-releasing slag. The electrode deposits X-ray quality weld metal.
