Description

Steels: Metallurgy and Applications deals with the metallurgy and applications of steel and covers the broad spectrum of the mainstream commercial grades as well as the service or manufacturing requirements that govern their use. Standard specifications and some of the design considerations that provide satisfactory service performance are considered. Brief reference is also made to some of the steel prices that were effective on January 1, 1991. Comprised of five chapters, this book begins with an overview of technological trends in the steelmaking industry since 1980s, paying particular attention to energy conservation, iron-making, continuous casting, and product requirements. The next chapter is devoted to low-carbon strip steels and their cold-forming behavior, applications, and metallurgical factors affecting cold formability. The third chapter focuses on low-carbon structural steels and their strengthening mechanisms, while the fourth chapter considers engineering steels and their heat treatment aspects. The final chapter describes stainless steels and their composition-structure relationships, commercial grades, corrosion resistance, welding, and cold working. The mechanical properties of stainless steels at elevated and sub-zero temperatures are also examined. This monograph will be of interest to students and practicing metallurgists.
