Description
Characteristics:
LKE-NiCrMo-6 are AC,DC electrodes. For electrodes 3.2mm and less in size are suitable for all position and excellent weldability. Proper base metals are ASTM B333/334/353/522/553.
Applications:
For joining application of 9% Ni steel storage tank on LNG or liquefied Nitrogen, stabilized,non-stabilized Austenitic Cr Ni steel grades and cryogenic Ni steel with quenching and tempering.
Notes on Usage:
1.Dry the electrode at 350-400°C for 60 minutes before use.
2.Keep the arc as short as possible.
3.Crater should be ground smooth or crater treatment.
