Key features
- Basic MMA electrode suitable for the welding of stainless steels type AISI 309.
- Particularly suitable for the welding of dissimilar steels (stainless steels to carbon steels).
- Weld deposit carbon content is 0.04% max
- Service temperature up to +1000°C, at elevated temperatures the Mo content improves the creep properties.
- Excellent weldability with a spatter free arc
- Self-releasing slag, efficiency 100%
