AWS A5.4: E308H-15 | DIN EN ISO 3581-A: E 19 9 H B 22 | Werkstoff Nr: 1.4948
Creep-Resistant, High Temperature Stable, Clean Bead Appearance
Summary:
Basic-coated, low hydrogen stainless electrode for welding austenitic stainless steels like 304H and 308H. Designed for elevated temperature service, it offers soft fusion, minimal spatter, excellent restrike, and smooth slag detachment. Enhanced carbon content improves creep strength and performance in high-temperature pipelines and reactors.
