Stainless Steel Alloys
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 used when high strength or high formability is the main objective; (2) chromium nickel alloys used for high temperature oxidation resistance; and (3) chromium, molybdenum, nickel, and nitrogen alloys used for applications where corrosion resistance is the main objective.
This chapter provides information on the structure, design aspects, mechanical properties, forming, machining, and corrosion resistance characteristics of duplex stainless steels. The different types of corrosion covered are general corrosion, pitting corrosion, crevice corrosion, and stress corrosion cracking.
