- Resistance to stress corrosion cracking (SCC) in chloride-bearing environments
- Resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulfide
- Resistance to general corrosion, pitting and crevice corrosion
- Resistance to erosion corrosion and corrosion fatigue
Good
- Hot-working properties
- Weldability
