描述
特性:
LKE-NiCrMo-4 is a nickel based low hydrogen type covered electrode which contains less C and Si to reduce carbide precipitation in grain boundary. The excellent heat resistance and corrosion resistance are obtained for chemical plant and FGD equipments
應用:
It is suitable for HASTELLOY C-276 and dissimilar metal welding.
使用注意事項:
1.在 350-400℃ 下烘乾電極 for 30-60 minutes before use.
2.使用較小的安培數並儘量保持較短的電弧
