耐腐蚀性
Good for sea water service
Especially good for pitting corrosion, stress corrosion and corrosion fatigue
Good fouling resistance
其他用途 & 评论
Variety of wrought specifications available, good for trim material
Low magnetic permeability
Non-sparking; can be used for oxygen service
Reasonable thermal and electrical conductivity
Good Castabilty with suitable design
Weldable
Can be heat treated to improve sea water corrosion properties
注意事项
Low modulus of elasticity, but good yield stress
- Raised face flanges non-standard
High temperature use
- Observe pressure ratings at higher temperatures
Should not be used in polluted / H2S containing sea water (in common with 316 Stainless)
