Abstract Streaks of austenite-rich and ferrite-rich bands produce during thesoaking at α+γ region because of the re-distribution of elements. Part of the aus-tenite formed at intermediate temperatures transforms into martensite while thesteel was cooled down to room temperature. The structure which consists of finemartensite and austenite exhibits a moderate strength and high enough cryogenictoughness. One of the important cause of the excellent cryogenic properties is thatthe precipitated austenite absorbs the impurities and thus purifies the matrix of thesteel.

Key words: 9%Ni steel precipitated austenite cryogenic toughness
