Corrosion engineers today spend enormous amounts of time and money searching multiple detailed sources and variable industry-specific standards to locate known remedies to corrosion equipment problems. Corrosion Atlas Series is the first centralized collection of case studies containing challenges paired directly with solutions together in one location. The fourth release of content in the series, Corrosion Atlas Case Studies: 2025 Edition, gives engineers expedient daily corrosion solutions for common industrial equipment, no matter the industry. Providing a purely operational level view, this reference is designed as concise case studies categorized by material and includes content surrounding the phenomenon, equipment appearance supported by a color image, time of service, conditions where the corrosion occurred, cause, and suggested remedies within each case study. Additional reference listings for deeper understanding beyond the practical elements are also included. Rounding out with an introductory foundational layer of corrosion principles critical to all engineers, Corrosion Atlas Case Studies: 2025 Edition delivers the daily tool required for engineers today to solve their equipment's corrosion problems. - Solves equipment failure with easy-to-find remedies organized by essential elements such as materials, system, part, cause, environmental, and phenomenon - Grasps fundamental corrosion elements on all major industrial pieces of equipment, no matter the industry - Identify failures by appearance with color figures within each case study - Provides correlation between avoiding corrosion and net-zero and sustainability
