stainless duplex pipe

<

2 Inch ASTM A789 S32750 F60 Seamless Duplex Pipe 60.3mm

Outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments, Pitting Temperature exceeding 50°C.

Physical Properties
Density: 0.278 lb/inch3
Melting Point: 2525- 2630°F
Poisson's Ratio: 0.3
Electrical Resistivity: 481 Ohm - circ mil/ft

Features:
Good general corrosion resistance
High strength
Good sulfide stress corrosion resistance
Useful up to 600°F

1.Good sulfide stress corrosion resistance
2.High Strength
3.Good weldability and workability
4.Good general corrosion resistance

At low temperature duplex stainless steel have better ductility than the ferritic and martensitic grade.Duplex grade can readily be used down to -50°C

Using a welded tube is typically a more cost effective option for use in low pressure, ornamental, and structural applications.
