Microstructure
Ferrite-Austenite

Special notes
The content of delta ferrite in the untreated weld metal is 25 - 35 %. The weld metal has particularly good resistance to pitting, crevice corrosion and stress corrosion cracking in aqueous media containing chloride.

Re-drying
2 h at 200 - 250°C. However, the cladding can withstand re-drying up to + 350°C
