Bohler Fox E 308 H (Heat Resistant) Stainless Steel Stick Electrodes
The Bohler Fox E 308 H are specialised, heat resistant, creep resistant rutile basic covered stick electrodes engineered explicitly for high temperature structural welding.
Unlike standard L-grade stainless steel electrodes designed primarily for wet corrosion resistance, the 308H formulation optimises carbon content to maintain mechanical integrity under extreme thermal stress.
Features
- The chemistry maintains carbon precisely within a 0.04–0.08% window to deliberately provide higher tensile and creep rupture strength over long periods at elevated temperatures
- Features a carefully controlled ferrite content (typically 3–8 FN) to ensure a balance between hot-crack resistance and long-term micro-structural stability under thermal cycling.
- The rutile-basic flux coating ensures a stable arc, minimal spatter formation, and clean weld profiles across standard AC and DCEP power sources
Technical Data
- AWS A5.4: E308H-16
- EN ISO 3581-A: E 19 9 H R 4 2.
- Ideal for welding unstabilised austenitic stainless steels, such as AISI 304H, 1.4948, and similar creep-resistant CrNi steels.
- Specifically designed for service temperatures exceeding 500°C
