說明 Characteristics. These electrodes will have a graphitic (black) coating and are suitable for application on cast iron. Although the deposited metal is relatively brittle, crack-free deposits can be made with controlled procedures. Deposits can be machined providing they are slow cooled from an annealing temperature.
Applications. EFe4 weld metal is used to rebuild worn cast iron machinery parts subject to metal-to-metal rolling or sliding contact. Although EFe4 weld deposits are compatible with carbon and low-alloy steel, EFe2 electrodes generally are preferred for such applications.
