Strength And Ductility

This chapter describes the causes of cracking, embrittlement, and low toughness in carbon and low-alloy steels and their differentiating fracture surface characteristics. It discusses the interrelated effects of composition, processing, and microstructure and contributing factors such as hot shortness associated with copper and overheating and burning as occur during forging. It addresses various types of embrittlement, including quench embrittlement, tempered-martensite embrittlement, liquid-metal-induced embrittlement, and hydrogen embrittlement, and concludes with a discussion on high-temperature hydrogen attack and its effect on strength and ductility.

Alloy Steels

High-strength steel tube HCM9M (LowC-9Cr-2Mo) steel, which shows the intermediate high-temperature strength between austenitic stainless steels and commercial low-alloy steels, has been developed. It has superior weldability, workability and oxidation resistivity. At present HCM9M tubes have been in-service test as reheater and superheater tubing at the 165,000 kW boiler in Japan without trouble. This report deals with the practical properties of HCM9M steel, service test experience and high temperature strengthening mechanism of the steel from morphological viewpoint of carbide.
