G-TECH 318
SMAW
- AUSTENITIC STAINLESS STEELS
318
Description
Nb stabilized, Mo bearing Rutile-basic coated electrode
Its basic-rutile coating ensures an excellent combination of welding performance in all positions, except for vertical down, and a high resistance to cracking providing smooth arc transfer. Excellent weldability with a spatter free arc and self-releasing slag result in a very smooth bead appearance. These electrodes are used to weld Ti or Nb stabilized grades of Mo bearing austenitic stainless steels. It is also used for depositing corrosion resistance overlays and valve seat inlays on medium carbon alloy steel.
