Welding Metallurgy and Weldability of Stainless Steels (2005)
by John C. Lippold and Damian J. Kotecki
ISBN 0-471-47379-0. Wiley Interscience, Hoboken, New Jersey. 2005. Hardcover. 376 pages. $115.
The book begins with an excellent background into the physical metallurgy of stainless steels with emphasis placed on the role of alloying elements and their effects on mechanical properties, corrosion behavior, and phase equilibria. I found that this technical information is extremely useful for the selection or application of stainless steels.
After the general introduction of stainless steel, each of the various types of stainless steels (i.e., austenitic, ferritic, martensitic, duplex, and precipitation hardening) are discussed separately. I found this to be very practical and logical in organization; each type of stainless steel was discussed separately and in detail regarding welding characteristics, weldability, filler metal selection, or suitability, selection of preheat, interpass, and post-weld heat treatment temperatures. If you needed to find specific information for a particular grade of stainless steel, you could use the index and go to the source in the text. If you needed to have more background information, you could start at the beginning of the applicable chapter.
What I especially found beneficial was the technical rationale for proper selection of a particular preheat temperature or interpass temperature, and the post-weld heat treatment for the particular type of stainless steel. This information is not something that can be easily found in most metallurgical reference books. In addition, the various types of damage or failure mechanism discussions related to weldability were very helpful.
The case histories presented at the end of each chapter were supportive of the technical information that was discussed earlier in the chapter. However, I would have liked more case histories to corroborate the technical discussion in each chapter. Overall, the case histories were rather interesting.
Some of the technical areas of the book that were of relevance to a practicing metallurgical or welding engineer were the expanded discussion on stainless steel solidification features, solidification cracking mechanism, general information on duplex stainless steels, and especially background information and weldability characteristics of precipitation-hardening stainless steels. I also felt that the information presented on dissimilar metal welds was very beneficial with excellent rationale for selection of appropriate filler metals.
The technical content of the book is suited for a senior or graduate-level student studying metallurgical or welding engineering. It would serve as a reference book for a practicing metallurgical or welding engineer. The figures and tables were well organized, descriptive, and supplemented the text in the various chapters. The macro and microphotographs were crisp in detail. The cover of the book was attractive, and the presentation of the table of contents was comprehensive and logically ordered. The use of appendices was excellent in listing the various grades of stainless steels and etchants.
What I found very useful were the tables that summarized the effects of post-weld heat treatment (PWHT) on mechanical properties for the various grades of stainless steels, types of precipitates in austenitic stainless steels, and the phase diagrams depicting phase equilibria for various alloy additions—very practical information for industrial applications regarding weldability of stainless steels. Detailed explanation on careful selection of PWHT to avoid austenite reformation in martensitic stainless steels was also very beneficial.
My overall rating of Welding Metallurgy and Weldability of Stainless Steel is excellent. It is on the same level as other notable reference materials on stainless steels such as Welding Metallurgy by Sindo Kou and the Physical Metallurgy Handbook by Anil Sinha. This book also treats the subject of welding and weldability of stainless steels in greater detail than the famous Handbook of Stainless Steels by Peckner and Bernstein. The reviewer noted one editorial revision: Page 96, second paragraph, about 5th sentence down, should read "because of the higher solubility of carbon in austenite" not "is austenite."
