Stainless steels are frequently classified according to their microstructure into five types:

austenitic, ferritic, martensitic, duplex (ferritic-austenitic), and precipitation-hardenable

(PH). More common types, such as the austenitic, ferritic, and martensitic stainless steels,

have been discovered in the first decade of the 20th century. This brief historical introduction

[1-4] initially deals with the century before the actual discovery of stainless steel and the

following section will describe the discovery of each of the five types of stainless steels.
