CLASSIFICATION

AWS A5.4 E2209-17 | EN ISO 3581-A E 22 9 3 N L R

PRODUCT DESCRIPTION

Rutile based flux formulated electrode for welding ferritic-austenitic stainless steel. The flux is concentrically extruded onto a fully alloyed core wire and bound by a blend of silicates that assures both coating strength and resistance to subsequent moisture absortion

WELDING FEATURES OF THE ELECTRODE

This unique flux formulation ensures excellent arc stability, ease of initial arc strike and re-strike minimal spatter on AC and virtually none on DC+. The resultant weld seams are smooth, evenly rippled and free from undercut while slag detachability is excellent. Metal recovery is some 103% with respect to core wire weight

APPLICATIONS AND MATERIALS TO BE WELDED

For welding standard 22% Chrome-Duplex Stainless Steels. Typical examples being: ASTM A182 Gr F 51 A890 Grade 4A
EN X 2 CrNiMoN 22 5 3Proprietary alloys include Sandvick SAF 2205, Avesta 2205, Bohler A903,Sumitomo SM 22Cr, Nippon NK Cr22

OTHER DATA

Electrodes that have become damp should be re-dried at 200-250^oC for 1 hour before use
