Product Name :Cast Iron Welding Electrodes
Material :Cast Iron
Diameter - Value :2.0mm, 2.5mm, 3.2mm, 4.0mm, 5.0mm (standard sizes for different welding thicknesses)
Coating Type :Graphite-based (for high carbon content), Titania-calcium, Low-hydrogen, or Nickel-alloyed (varies by model, e.g., EZNi uses nickel-rich coating for crack resistance)
Deposited Metal C Content :EZC: 3.0–4.0%, EZNi: ≤0.1%, EZNiFe: ≤0.15% (carbon affects hardness and weldability; lower carbon in nickel-based electrodes reduces cracking risk)
Deposited Metal Ni Content :EZC: 0%, EZNi: ≥90%, EZNiFe: 45–60% (nickel enhances ductility and compatibility with cast iron)
Tensile Strength :EZNiFe: 300–400 MPa, EZNi: ≥290 MPa (measures weld joint strength under tension)
Elongation :EZNiFe: ≥10%, EZNi: ≥15% (percentage of lengthwise deformation before fracture, indicating weld ductility)
Impact Toughness :EZNiFe: ≥27 J at -20°C (resistance to sudden loading; critical for dynamic applications)
Applicable Welding Positions :Flat, Vertical, Horizontal, Overhead (most nickel-based electrodes support all-position welding; iron-based electrodes may be limited to flat/horizontal positions)
