Z408 cast iron welding line with GB EZNiFe-1 rather AWS ENiFe-C1 
 Description: Z408 is a nickel-iron alloy solder core, strong reduction of the iron coating of graphite electrodes, high strength, good plasticity, low coefficient of linear expansion. Crack resistance of gray cast iron and the Z308 is almost, but cast iron is stronger than the Z308, and high phosphorus content (0.2% P) of cast iron, also has good results, cutting slightly worse performance than the Z308 and Z508. For room temperature or slightly preheated (to about 200 ℃) gray iron and ductile iron welding. AC and DC. 
 Uses: Suitable for important high-strength gray cast and ductile castings welding. Such as cylinder, engine blocks, gears, rollers and so on.
