Aero Steels: Part 2—High Alloy Steels

Abstract

Highly alloyed steels (total alloying element content more than 8 wt%) are generally classified as secondary hardening steels, maraging steels and precipitation hardening (stainless) steels. The effects of alloying elements on microstructure and mechanical properties are briefly described in this chapter. The manufacturing procedures and optimum processing parameters are discussed, and the heat treatment schedules and achievable properties are tabulated. Details on machining and weldability of these steels are also provided.
