      Z408Nickel ferroalloy welding core, strong reducing graphite cast iron welding type medicine leather, high strength, good, first developed low expansion coefficient, the anti-cracking characteristics of gray iron and z308 almost

       But for ball mill cast iron is strong, z308 to the phosphorous higher cast iron, also have good effect, machinability is a bit poor, than z308 for normal temperature or slightly preheat (200 degrees Celsius) or so, gray iron and ball mill iron welding, ac/dc amphibious, arc stability, convenient operation.

NOTE 

 Before welding electrode in 150 degrees Celsius must be approved by a baking 1 hour
