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)
