Abstract
Although possessing superior properties, stainless steels are still afflicted by a host of problems, especially when they are exposed to elevated temperatures. Problems covered in this chapter are: hydrogen embrittlement, sensitisation, metal dusting, pitting corrosion, microbiologically-induced corrosion, high-temperature oxidation, stress-corrosion cracking, fatigue, creep, and dynamic strain ageing. The emphases of this chapter are on the recent findings on the underlying mechanisms of these problems, the main factors affecting them, new methods for their alleviation/elimination and detection, and modelling.
