This article provides an overview of austenitic manganese steels. It describes the standard composition ranges of commercial products and explains how various alloying elements affect mechanical properties, processing, and performance. The article also discusses special grades of manganese steels and the types of applications for which they have been developed.

This chapter defines low-temperature and cryogenic steels and describes their alloy classifications and their ambient and low-temperature properties. These steels include ferritic carbon and low alloy steels, martensitic low alloy steels, martensitic high alloy steels, and austenitic high alloy steels.
