| 說(shuō)明 | Characteristics. EFeCr-A8 is a higher chromium version of EFeCr-A3. The deposit contains hexagonal chromium carbides in an austenitic matrix and has a hardness of 50–60 HRC. The increased chromium content tends to decrease the toughness while increasing the abrasion resistance. Maximum relief checking can be expected. The weld metal may be applied to carbon, alloy, or austenitic manganese base metals. Applications. Weld metal is frequently used for applications involving low stress abrasion combined with minimum impact. |
