AWS Cast iron welding rod Z308 AWS A5.4 stainless Steel welding electrode E308-16 Introduction: Z308 is a kind of cast iron electrode with pure nickel core wire and strong reducibility graphite type coating. When welding, the preheating of the weldments can be left out. It has excellent crack-resistance and machinability. Due to the expensive nickel, it can only be used when other kinds of électrodes are not suitable. AC/DC. Application: Used for repair welding on thin cast iron pièces and machined surfaces, such as some key gray cast iron pièces like engine bearers, guide rails of machine tools, pinion stands, etc. Chemical Composition of Deposited Métal (%) Chemical Composition C Mn Si S Ni Fe Total Quantity of Other Eléments Requirement =<2.00 =<1.00 =<2.50 =90 =58 =51.00 Typical Value 0.591 0.071.50 0.004 94.00 0.021 — Diameters/Length/Reference Current (AC or DC+) Electrode Diameter (mm) 2.5 3.2 4.0 5.0 Electrode Length (mm) 300 350 350 350 Welding Current (A) 60-90 90-120 130-180 190-220
