Corrosion of Constructional Steels in Marine and Industrial Environment

The book entails investigative methods for better understanding of the degradation process and uses of high performance paints formulation and also compares them on mild steel (MS) and weathering steel (WS) through various AC/DC electrochemical test methods and surface characterization through electron microscopy, XRD and Raman spectroscopy. This book also deals with the corrosion studies undertaken considering three phases (solid, liquid and gas) with latest techniques and the emphasis has also been given on degradation of materials due to atmospheric corrosion as this is of immense interest to present engineers and researchers.
MS has got versatile application as structural steel for construction of buildings, bridges, flyovers, pipelines etc. But this is very much prone to corrosion in industrial and marine environments in presence of harmful pollutants and other industrial effluents in addition to normal humid atmosphere. These corrosion problems are much severe in a tropical country like India with vast coastline. MS corrodes relatively faster and thus leads to colossal loss in every year and to reduce this loss some kind of protection in the form of paints and coatings is always used. Painting is an effective means but quite costly amounting 10-15% of the initial construction cost of superstructures besides cost of repainting at regular interval.

Dr. Jayanta Kumar Saha is serving with Institute for Steel Development & Growth (INSDAG) as Deputy General Manager spearheading key activities like sourcing, corrosion, fire protection, tech advisory services of steel structures. He did his graduation from Bengal Engineering & Science University, Shibpur, Kolkata in Metallurgical Engineering, Post-graduation from Indian Institute of Technology Madras in Production Engineering and Ph.D. in Metallurgical & Material Engineering from Jadavpur University, India. He is an IRCA, UK accredited lead auditor for ISO 9001. He has authored 11 INSDAG books on steel applications and has credit of 20 papers published in national and 5 papers in international journals. He is representing various national bodies/committees. He had previous experience at Hindustan Aeronautics Ltd, Central Mechanical Engineering Institute and Philips India Ltd. He has visited several countries like UK, Netherlands, China, South Korea and Singapore, etc., in connection with the pioneering work in steel applications.
