Stick Electrodes MTC MT-NiFe 2.4560

MT-NiFe – Nickel-Iron Rod Electrode for High-Quality Cast Iron Welding

The MT-NiFe is a basic-graphitic coated rod electrode with a nickel-iron core rod for reliable welding of cast iron. It was specially developed for dissimilar cast iron welding and is ideal for repair, maintenance, and surfacing welding.

Its nickel-iron alloy enables a particularly well machinable weld seam and reduces the risk of cracking in difficult-to-weld cast materials.

Standard Designations

• EN ISO 1071: E C NiFe 11

• AWS/ASME SFA-5.15: E NiFe-CI

---

Applications

• Cast iron with nodular graphite (EN-GJL-100 / GG10 to EN-GJL-350 / GG35)

• EN-GJS-400 (GGG40) to EN-GJS-700 (GGG70)

• Joint welding of cast iron

• Surfacing welding on cast iron

• Repair welding of gray cast iron and menderite cast iron parts

• Particularly suitable for ductile cast iron

The electrode is optimally suited for cold welding. The weld seam and weld transitions can be machined very well.
