DIN 2631 FLÄNSAR EN ASME B16.5 Plan svetsfläns Flanges Typ 01 UNS
S32760 (1.4501 / F55) Steel Blind pipe flanges
The alloy is supplied with a PREN(Pitting Resistance Equivalent) at
>=40.0 which guarantees high resistance to pitting corrosion. In
addition, the steel offers high resistance to crevice corrosion and
stress corrosion cracking. Ambient and sub-zero (down to minus
50°C) notch ductility is good. These attributes mean that this
super duplex steel can be used successfully as an alternative to
300 series stainless steel (such as Type 316 ), standard 22% Cr duplex steel and precipitation hardening
stainless steels. Where appropriate the alloy can be considered in
lieu of more costly Grade 5 titanium or nickel-based alloys.
The steel combines high mechanical strength (typically up to 600
MPa yield strength) and good ductility with outstanding corrosion
resistance to marine environments and a wide, diverse range of Oil
& Gas production environments.
