Deskripsi
Karakteristik:
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
Aplikasi:
It is suitable for HASTELLOY C-276 and dissimilar metal welding.
Catatan tentang Penggunaan:
1. Keringkan elektroda pada suhu 350-400 ℃ for 30-60 minutes before use.
2. Gunakan arus listrik yang kecil dan jaga agar busurnya sependek mungkin
