Description
Characteristics:
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.
Applications:
It is suitable for HASTELLOY C-276 and dissimilar metal welding.
Notes on Usage:
1.Dry the electrode at 350-400°C for 30-60 minutes before use.
2.Use small amperage and keep the arc as short as possible.
