DIN 8556 E199LR26
DESCRIPTION
A rutile flux coated electrode designed for the welding of low carbon 18% Cr / 10% Ni, type 304L, 304 austenitic stainless steel. Operability is excellent with a low spatter arc, producing a smooth weld bead surface and self-releasing slag. The deposited welds are of radiographic quality.
