HFM 15S
Basic coated electrode for creep resisting steels
Description & applications
Low hydrogen basic coated electrode with Cr and Mo for welding creep resisting steels (1% Cr - 0.5% Mo). Resistant to high temperature up to 500-550°C. For piping systems, boilers, overeaters. Soft fusion, good slag removal. Nice aspect of the weld bead.
Main applications: petrochemical industry and chemical industry.
Steels and pipes for boilers and pressure vessels:
