Steel corrosion can be significantly influenced by various metallurgical factors. This book focuses majorly on metallurgical intrinsic factors that influence corrosion. It systematically analyzes the latest advances in the mechanism of steel corrosion induced by various metallurgical intrinsic features of steel to support the development of corrosion-resistant steels. It discusses how several typical metallurgical factors such as inclusion control, alloying control, and heat treatment control influence the corrosion resistance of stainless or low alloy steels. This book strongly supports metallurgical and materials researchers and engineers in developing new corrosion-resistant steels.
