LOW HYDROGEN ELECTRODES
OK 76.35 (Non-Stock Item — Indent Orders only)
Type: Basic SMAW E8015-B6
OK 76.35 is an LMA electrode containing 5Cr0.5Mo for welding creep-resistant steels, especially good for pipe welding. The electrode runs with
a quiet, stable arc and gives a minimum amount of spatter loss. Preheat and interpass temperature 150-2600C is normally required. Mechanical
data after heat treatment 8500C, 2h.
