The 9% nickel steel is a low-carbon nickel alloy steel with nominal composition of 9Ni, which is particularly used for low-temperature or cryogenic pressure vessels and plants for processing, transportation, and storage of LNG down to -196°C [-320°F]. For this reason, alloy development has focused on ferritic steels containing 9–12% Cr. Optimisation of C, Nb, Mo and V and partial substitution of W for Mo in the 9–12% Cr ferritic steels has resulted in three new alloys, HCM12A, NF616 and E911, which are capable of operating up to 620 °C at steam pressures up to 35 MPa.
