A CHEMICALLY BASIC FLUX COATED MMA ELECTRODE DEPOSITING A NICKEL BASED ALLOY HIGH IN BOTH CHROMIUM AND MOLYDENIUM
NCM-276
CLASSIFICATION
AWS A5.11 ENiCrMo-4 | EN ISO 14172 E Ni 6276 | JIS Z 3224 DNiCrMo-4
PRODUCT DESCRIPTION
The chemically basic flux is extruded onto a pure nickel core wire. The flux contains chrome & molybdenum also other remaining alloying elements together with alloys for deoxidation and grain refinement. The blend of silicates used during electrode production ensure both coating strength and resistance to subsequent moisture absorption.
WELDING FEATURES OF THE ELECTRODE
The electrode is suitable for use on both AC and DC+ and welds with great arc stability and thus control of the molten weld pool. Slag detachability is good. The weld beads are bright and evenly rippled with fillet welds slightly convex. Strike and re-strike should be made with the established back step technique.
APPLICATIONS AND MATERIALS TO BE WELDED
Used for welding NiCrMo alloys of the following specifications: ASTM UNS N10276 A494 CW - 12HW A743/A744 CW - 12Mn Proprietary Alloys: HASTELOY ALLOY C276 (Haynes). INCO-ALLOY C276 (special metals). NiCroFer 571h Mo W (VDM)
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 180oC for 1 hour.
