This chapter focuses on precipitation-hardening stainless steels (PHSSs). The three main
types of PHSSs, i.e., the semiaustenitic class, the martensitic class and the austenitic class, are described
in detail. The duplex class is also briefly discussed. The different heat treatments, together with their
effects on properties, that are commonly used for attaining precipitation strengthening in PHSSs are
presented. Recent developments in the understanding of the precipitation sequences and the precipitates
in PHSSs are introduced.
