CLASSIFICATION

AWS A5.4 E310Mo-16 | JIS Z 3221 D310Mo-16

PRODUCT DESCRIPTION

A unique rutile based flux formulated with very low levels of acid and amphoteric minerals combined with small alloy additions to compensate for arc losses. 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 absorption.

WELDING FEATURES OF THE ELECTRODE

The electrode is used to best advantage on DC+ but is also stable on AC. Weld beads are smooth and slag detachability is good. Because weld metal silicon is low by design to reduce solidification cracking (a feature common to all ferrite free austenitic alloys), the weld profile is more u-convex than normal

APPLICATIONS AND MATERIALS TO BE WELDED

Applications for the electrode are found in the Chemical and Petro-Chemical Industries for welding similarly alloyed heat resisting castings or 316L clad plate. The electrode may also be used to deposit overlays on carbon steels.

OTHER DATA

Electrodes that have become damp should be re-dried at 150oC for 1 hour
