E7024 Iron Powder Electrode Nikko GA 24 5,0mm

Iron Powder High Deposition E7024 Welding Electrode - 5.0 mm Diameter x 450 mm long Nikko Steel GA24 High deposition welding electrode for use in the flat or horizontal welding positions. A rutile based flux with a high iron powder content that also contains the necessary alloying and deoxidising elements. The fluid slag has a short freezing range allowing excellent deposition rates to be achieved. The flux is extruded onto a mild steel core wire that ensures coating strength and stability. Metal recovery is some 180% with respect to core wire weight. What can you expect from these Nikko GA24 Iron Powder Electrodes The arc is stable on both AC and DC. Arc strike and re-strike are instant. Weld seams are smooth and evenly rippled. Slag detachability is excellent, often selfdetaching. The high metal recovery ensures improved welding economics. Fillet welds are of a mitred to very slightly concave profile. Types of material to be welded Butt welds in the flat (downhand) position and fillet welds in the flat and horizontal positions with the following materials: Mild and medium carbon-manganese steels up to 15mm thick with a UTS of 500N/mm2 max. Typical grades : BS 1449 plate and sheet, BS 4360 grades 43A and 43C, Lloyds A & D ship steel BS 4360 grade 50B Lloyds grades AH and DH, BS 3059 and BS 3601 grade 320-410 API 5L A-B and X42.
