CLASSIFICATION
AWS/SFA 5.4 E308L-16, BS 2926 E19.9.L.R
DIN 8556E199LR26
DESCRIPTION
A medium heavy coated, rutile type AC/DC 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 electrode deposits X-ray quality weld metal.
