Description:
Z308 is a nickel-based welding core, strong reductive graphite-type coating of cast iron electrodes. AC and DC can be used. Welding arc stability, easy to operate, the weldment do not need to preheat. In the cast iron cold welding, it is crack resistance, machinability, weld strength and better overall performance of a welding rod is widely used in thin cast iron And the welding surface processing.
Application:
used for welding gray cast iron. Thin cast iron and processing the surface of the welding, such as cylinder head, engine block, machine rails, motor shell, gear boxes and other important gray cast iron parts. Also applies to welding cast iron made of mechanical parts. Soft after welding, can be machined, high crack resistance, welding engine can be repaired products.

Name: cast 408 cast iron nickel iron electrode
Standard: GB / T10044 EZNiFe-1 AWS A5.15ENiFe-CI
Composition: C = 2.0%; Si¡Â4.0%; Mn¡Â2.5%; Ni = 45-60%; Fe = balance; S¡Â0.03%.
Description:
Z408 is nickel-iron alloy core, strong reductive graphite coating of iron electrode, with high strength, good plasticity, low coefficient of linear expansion. Cracking resistance to gray cast iron is similar to that of Z308, but to ductile cast iron is stronger than that of Z308. Cast iron with a high phosphorus content (0.2% P) also has good results, and the machinability is slightly worse than Z308 and Z508. Used at room temperature or slightly preheated (to about 200 ¡É) gray cast iron and ductile iron welding. AC and DC.
Application:
Suitable for welding high strength gray castings and ductile castings. Such as cylinders, engine blocks, gears, rollers and so on. high strength after welding, not machinable, suitable for welding products with high seismic strength, good crack resistance.
Hardness: HB200
Name: cast 508 nickel-copper cast iron welding rod
Standard: GB / T10044 EZNiCu-1 AWS A5.15 ENiCu-B
Composition: C = 0.35-0.55%; Si¡Â0.75%; Mn¡Â2.3%; Ni = 60-70%; Cu = 2.5-3.5%; Fe = 3.0-6.0%; S¡Â0.025%.
Application:
Suitable for repairing welding of gray cast iron at room temperature or slightly preheated (up to 300 ¡É), or for repairing cracks and trachoma of gray cast iron which do not need high strength, the cutting performance is close to that of Z308 pure nickel cast iron Welding.
low strength after welding, processing performance, suitable for repair cast iron.
