10 x Cast Iron Electrodes MTC MT-NiFe 2.5 / 3.2 mm Cast Iron Welding

10 x Cast Iron Electrodes MTC MT-NiFe 2.5 / 3.2 mm Cast Iron Welding

• Quantity: 10
• AC: lowest heat input, favourable for fill pass welds
• Positive pole: higher welding speed, less penetration, higher beads
• Negative pole: pulsating arc, deep penetration, good sidewall fusion, flat beads
• Special notes: Universally applicable stick electrode for repair welding on cast iron parts. Weld short beads (30 - 50 mm), peen weld beads immediately and thoroughly to relieve stress. By appropriately choosing the polarity when welding with DC, certain properties can be achieved.
• Standard designation:
  DIN 8573: E Ni - BG 1
  EN 1071: E C Ni CI 1
  Material number: 2.4155
  WS/ASME SFA-5.15: E Ni - CI
  
  
  Most important application areas:
  Cast iron with lamellar graphite according to DIN 1691, e.g. GG . 10 to GG - 35;
  white and black malleable cast iron according to DIN 1692.

  Elongation A5: 5%
  Brinell hardness HB 10/3000: 160
  
  
  
  Typical analysis of pure weld metal in %:
  C: 0.5 (precipitated as graphite)
  FE: 2.5
  Ni: Base
