說明 Characteristics. Weld metal deposited by these electrodes is an air-hardening tool steel type with high room temperature hardness (55–60 HRC). Deposits can be applied crack-free with careful procedures. The deposits cannot be machined and generally are ground when finishing is required.
Applications. EFe3 electrodes are used to overlay surfaces and edges requiring high hardness and crack-free deposits, such as the edges of tools and dies. Deposits are compatible with many tool steels. Although generally used for metal-to-metal applications, EFe3 weld metal performs well in earth abrasion applications where high impact is encountered.
