Bohler Fox FFB-A (Heat Resistant) Stainless Steel Stick Electrodes
A unique rutile based flux formulated with very low levels of acid and atmospheric minerals combined with small alloy additions to compensate for arc losses. The flux is concentrically extruded onto a fully alloyed core wire and bound by a blend of silicates that assures both coating strength and resistance to subsequent moisture absorption. The electrode is used to its best advantage on DC+ but is also stable on AC. Weld beads are smooth and slag detach ability is good. Weld metal silicon is low by design to reduce solidification cracking (a feature common to all ferrite free austenitic alloys), the weld profile is more u-convex than normal. Applications for the electrode are to be found in the Chemical, Petro-Chemical and Cryogenic Processing and Storage Industries as well as the Food, Brewery and Pharmaceutical Industries.
Features
- Exceptional scaling resistance at extreme high-temperature thresholds.
- Designed to run smoothly on both AC (alternating current) and DC+ (direct current positive).
- Features a specialised rutile-basic coating that provides a highly stable arc, minimal spatter, and self-releasing slag for clean finishes.
- Suitable for welding in multiple positions, including flat, vertical-up, and overhead.
Technical Data
- Suitable for all positions except vertical down
