G-TECH 800Nb
SMAW
- HIGH TEMPERATURE ALLOYS
800/800H
Description
Austenitic coated electrode for matching alloy 800
The electrodes are designed to match composition and properties of alloy 800. These alloys are used for their resistance to corrosion, thermal fatigue and shock at temperatures up to 1000°C. Typical applications include radiant tubes, reformer furnace outlet manifolds, pyrolysis furnace tubes in the petrochemical industry and nuclear engineering industries. Ease of slag removal reduces post-welding cleaning operations to a minimum.
