... Abstract This chapter discusses the compositions, mechanical properties, phase structure, stabilization, corrosion resistance, and advantages of austenitic stainless steels. Austenitic alloys are classified and reviewed in three groups: (1) lean alloys, such as 201 and 301, which are generally...

... and austenite in their structure gives them higher strength than either phase by itself. Duplex alloys have at least 20% chromium, so they are considered as highly corrosion-resistant alloys but not high-temperature alloys because of embrittling phases. Their low nickel content makes them more economical than...

... It can be seen that the elements that promote austenite, with the exception of cobalt, all depress the M s temperature. This puts a limit on the amount of total alloy that can be used and in the end puts an upper limit on the ability of martensitic stainless steels to achieve high corrosion resistance...
