Stick Electrodes MTC MT-NiFe 2.4560

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

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

Thanks to its nickel-iron alloy, it enables a particularly 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

---

Areas of Application

• Nodular graphite cast iron (EN-GJL-100 / GG10 to EN-GJL-350 / GG35)

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

• Joining welds on cast iron

• Build-up welds on cast iron

• Repair welds on grey cast iron and malleable cast iron parts

• Particularly suitable for spheroidal graphite cast iron

The electrode is optimally suited for cold welding. The weld seam and seam transitions are very easily machinable.
