Austenitic Stainless Steels

Pp. 23-40 (18)

Joseph Ki Leuk Lai, Kin Ho Lo and Chan Hung Shek

Abstract

This chapter gives a brief introduction to the compositions and uses of the various grades of steels in the austenitic class. The phenomena of deformation-induced transformation (DIM) and sensitisation are then covered. The underlying mechanisms causing DIM and sensitisation, together with the factors affecting them, are discussed in detail. Mechanical stabilisation, recent research findings on and methods for detecting DIM and sensitisation are also covered.

Keywords:

Austenitic stainless steel, metastable austenitic stainless steel, deformation-induced martensite, martensitic transformation, sensitisation, desensitisation, healing, mechanical stabilisation, phase diagram, ε martensite, α’ martensite, EPR test, grain boundary engineering.
