This is the book I never wanted to write, but always wanted to own. As a metallurgical engineer and long time user of steel standards, author of the four CASTI Metals Data Books, and member of ASTM A01 and B02 standard committees, I knew all too well the many pitfalls and challenges of writing such a handbook. There were many steel standards from around the world that were new to me, which created far too many surprises and delays in completing this book.

Comparing steel standards is not an exact science, so the biggest challenge of preparing such a book was deciding on the “rules of comparison.” Of the similar books on the market today, none explain in detail why one steel is comparable to another. They simply appear together in a list of steels. I kept a daily diary to help construct a workable set of comparison rules that I could share with other users to assist them in understanding how and why one steel is comparable to another.

To say the least, these rules changed from chapter to chapter while the book was being written. It wasn’t until the last chapter and appendix were completed that I was able to finalize the rules of comparison. In the end, a complete review of the book was performed resulting in the reorganization of some chapters and the fine-tuning of others. There were too many occasions when I thought the book was finished, only to have to change, add, or delete a rule which made yet another review of the book necessary.

After more than two years of researching steel standards and gathering data from around the world for the 2 nd and 3 rd editions of this handbook, then developing a comparison order to more than 100,000 pieces of data, this handbook is an ongoing and expanding project. The addition of a fully searchable e-book on CD-ROM makes this product even more valuable, since trying to find one piece of data in more than 100,000 is not an easy task. The e-book makes searching for a comparable steel a quick and easy process. In some cases, the user may find out that the steel is non-comparable.

I hope you enjoy using this handbook as much as I will. Tie a chain to it and anchor it to your desk,because once others see it, they’ll want to use your copy. I am interested in your comments and suggestions to improve this handbook, so I encourage you to send your feedback directly to ASTM.

John E. Bringas, P.Eng.

Comparing steel standards is not an exact science and there is no foolproof method. When you begin to use this book, you’ll quickly discover that there is no such thing as “equivalent” steel standards.

Then, consider the fact that not all steels have comparative counterparts and you’ll begin to understand the methodology used in this book. Before proceeding directly to the contents of this book, it is strongly recommended that you read Chapter 1, which includes a detailed explanation of the “rules of comparison” used in this book.

Since there was insufficient space on one page to place both the chemical composition and mechanical properties tables, they were split into two separate tables. To assist the user in keeping track of which comparison criteria were used for a given steel, each table within a chapter was sequentially numbered and appended with either the letter A or B. Table numbers ending in the letter A designate that the table was the main criterion used for comparison; whereas table numbers ending with the letter B were “mirrored” from the A table.

Each group of steel data in the tables is separated by two types of horizontal lines: black and grey. Black lines separate groups of steels that are more closely comparable to each other, whereas grey lines separate steel data within a comparative group.

Caution: do not confuse the thinner dividing black line within a table, with the thicker black line that borders the outside of the table. The pages are formatted to keep comparative groups together as much as possible. However, when a group of comparative steels extends to more than one page, a note is place at the bottom of the page to indicate that the comparative group continues on the following page, i.e., NOTE: This section continues on the next page.
