Key features
- In sulphur-free atmospheres the weld metal is non-scaling <1200°C, in sulphurous atmospheres the weld metal can be used <500°C.
- Used for joining ferritic to austenitic steels (dissimilar) with operating temperatures or postweld heat treatment >300°C.
- Very resistant to stress corrosion cracking and pitting corrosion in a range of media including phosphoric acid, organic acids, sea water and polluting environments
