Z408 cast iron electrode Model GB / T: EZNiFe-1 is equivalent to AWS: ENiFe-CI Description: nickel-iron alloy core welding, strong reducing strong graphite cast iron electrode with high strength, good plasticity, low coefficient of linear expansion. Crack resistance of gray cast iron and Z308 almost ductile iron is stronger than the Z308 also has a good effect on phosphorus-containing high (0.2% P) cast iron. Cutting than the Z308 and Z508 somewhat less, for room temperature or slightly after the warm-up (to about 200 ℃) gray cast iron and ductile iron welding, AC and DC, stable arc, good technology. Uses: used for high strength gray cast iron and ductile iron welding, such as cylinder, engine, seat gear. Difficult to process after welding
