| 說(shuō)明 | Characteristics. Filler metal deposited by EFeCr-A3 electrodes is similar to a deposit made using EFeCr-A1A electrodes except, due to the lower manganese content, a martensitic matrix is present, rendering the deposit somewhat brittle. These deposits are not machinable but may be finished by grinding where necessary. Applications. This weld metal is a general purpose hardfacing alloy for earth abrasion applications and is suitable for low stress scratching abrasion with low impact. |
