说明 Characteristics. Deposits made with these electrodes are a machinery grade steel suitable for application on carbon and alloy steels. With care, they can be applied crack-free. Deposits are machinable with carbide-tipped tools. Deposit hardness generally is in the range of 25–50 HRC with EFe2 electrodes providing weld metal with the higher hardness. These deposits contain sufficient alloy to attain full hardness without the need of heat treatment. Abrasion resistance is comparable to heat-treated steels of equal hardness.
Applications. These electrodes are used to restore worn machinery parts to their original dimensions.Deposit surfaces are suitable for metal-to-metal rolling and sliding contact, such as occurs on large, low-speed gear teeth,shafts, etc. High compressive strength makes these materials suitable as a base for more abrasion-resistant materials.
