This appendix is a collection of tables listing the chemical compositions of wrought ferritic steels; wrought stainless steels; cast corrosion- and heat-resistant alloys; wrought iron-, nickel-, and cobalt-base alloys; cast nickel- and cobalt-base alloys; oxide-dispersion-strengthened alloys; and iron-, nickel- and cobalt-base filler metals.

This chapter recounts some of the early efforts and milestones in the development of stainless steel powders and their use in powder metallurgy applications.

This chapter describes a number of corrosion testing methods for sintered stainless steels, including immersion, salt spray, and electrochemical tests, ferric chloride and ferroxyl tests, and elevated-temperature oxidation resistance tests. It also provides corrosion resistance and performance data from various sources.

This chapter discusses the sintering process for stainless steel powders and its influence on corrosion resistance. It begins with a review of sintering furnaces and atmospheres and the effect of temperature and density on compact properties such as conductivity, ductility, and strength. It then describes the relationship between sintered density and corrosion resistance and how it varies for different types of powders and operating environments. The chapter also explains how stainless steel powders respond to different sintering atmospheres, including hydrogen, hydrogen-nitrogen, and vacuum, and liquid-phase sintering processes.

Steels that resist corrosive attack from normal atmospheric exposure and contain a minimum of 10.5% Cr and 50% Fe are generally classified as stainless steels. Their special qualities lie in a chromium-rich oxide surface film that quickly regrows when damaged. This chapter discusses the classification, composition, properties, treatments, and applications of austenitic, ferritic, martensitic, duplex, precipitation-hardening, powder metallurgy, and cast stainless steels. It also reviews the history of stainless steels and provides information on alloy designation systems.

This chapter discusses the advantages of using powder metallurgy to produce magnetic materials, particularly its ability to control chemistry and near-net shape. It also explains how process parameters and powder characteristics influence the physical and magnetic properties of common stainless steels.

This chapter provides information on the properties and behaviors of stainless steels and stainless steel powders. It begins with a review of alloy designation systems and grades by which stainless steels are defined. It then describes the composition, metallurgy, and engineering characteristics of austenitic, ferritic, martensitic, duplex, and precipitation hardening stainless steel powders and metal injection molding grades.

This chapter discusses the composition and classification of stainless steels and focuses on the processes involved in heat treatment and applications of these steels. The wrought and the cast stainless steels covered are ferritic, austenitic, duplex (ferritic-austenitic), martensitic, and precipitation-hardening. In addition, information on special considerations for stainless steel castings is also provided. The heat treatment processes explained in the chapter are preheating, annealing, stress relieving, hardening, tempering, austenite conditioning, heat aging, and nitride surface hardening. Finally, some special considerations for stainless steel castings are discussed.

This chapter describes the most effective ways to improve the corrosion resistance of sintered stainless steels, including increasing alloy content, optimizing the sintering process, and the use of surface treatments and modifications.
