Typical Properties
Tensile ******0 N/mm2
Yield ******0 N/mm2
Elongation **- *5%
Hardness HB**0
Density 7.6 g/cm3
Good castability, reasonable bearing material, easy machining, high strength
P/T Ratings Shipham SPT*1 *9 bar for class **0
EN*****3:***3 *5.5 bar class **0
Corrosion Properties
Good for seawater service
Especially good for pitting corrosion, stress corrosion and corrosion fatigue
Good fouling resistance
Additional Uses & Comments
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 seawater corrosion properties
Cautions
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 seawater (in common with **6 Stainless)
