StarBlaze Prime 9018-G SPL
AWS A5.5: ~E 9018-G
Enhanced Moisture Resistance | High Strength | Suitable for Pressure Equipment & Power Plants
A low hydrogen, moisture-resistant basic type electrode designed for welding high tensile, fine-grained structural steels, particularly 16Mo3-grade and Cr-Mo-Ni-Mn alloyed steels. Offers excellent arc stability, all-position weldability, and high crack resistance. Ideal for construction of boilers, pipelines, penstocks, and structural components subjected to elevated temperature and pressure.
