Z408 Pure Nickel Cast Iron Electrode AWS ENiFe-CI

APPLICATIONS:

It is suitable for the welding of high-strength gray iron and nodular cast iron, such as cylinder, engine block, gear box,etc..

CHARACTERISTICS: Z408 is the cast iron electrode with nickel iron alloy core and strong reduction of graphite coating . It can be used in AC and DC dual purpose, has stable arc,and is easy to operate. The electrode has the characteristics of high strength, good plasticity, low linear expansion coefficient and so on. The crack resistance for grey cast iron is as much as that for Z308, while the crack resistance for nodular cast iron is more than Z308. For cast iron with higher phosphorus (0.2%P), it also has a good results and its tocutting performance is lower than Z308 andZ508 slightly. Z408 is used in the welding of gray iron and nodular cast iron for room ATTENTION: Before welding, the electrodes need to be baked for 1 hour with the temperature of 150±10℃ before using. When welding ,it is appropriate to take narrow weld and each weld length should not exceed 50mm. Hammer the welding area lightly with a hammer immediately after welding in order to eliminate stress and prevent cracks. Lower heat input is recommend. Chemical Composition of the deposited metal(the mass fraction): %
