CRA 2550E
NOMINAL COMPOSITION
Chromium 25% Nickel 50% Molybdenum 6% Tungsten 1.5% Iron Balance
CRA 2550E (UNS N06255) is a cold worked nickel-based alloy meeting the severe challenges of wells containing high chlorides,
H2S and temperature. With a typical Pitting Resistance Equivalent Number of 52 it is highly resistant to pitting corrosion and
chloride-induced stress corrosion cracking. For sour service applications, it is classified in MR0175/ISO15156 as a type 4d alloy,
with no restrictions to partial pressure of H2S below 300F and resistant to 300 psi H2S at 425°F.
