INTRODUCTION
This designer handbook has been written to provide the designer,
engineer, specification writer, producer and user of STAINLESS STEEL
with a listing of all the current ASTM (American Society for Testing and
Materials) standards. These standards are listed by mill shape (BAR,
SHEET, WIRE, etc.) and by product (bolts, fittings). Stainless types are
also listed, along with a selection of applicable society and military
specifications.
GENERAL INFORMATION
Stainless steel is not a single alloy, but rather the name applies to a
group of iron based alloys containing a minimum of 10.5% chromium.
Other elements are added and the chromium content is increased to
improve corrosion resistance and/or enhance mechanical properties.
There are over 50 stainless steel types originally recognized by the
AISI and are detailed in a designer handbook, “Design Guidelines for
the Selection and Use of Stainless Steel,”
The assumption is made that the reader is well aware of the various
types of stainless steels including the five metallurgical classifications
(austenitic, ferritic, martensitic, austenitic/ferritic-or-duplex, and
precipitation hardening). Where possible, these five classifications are
generally shown with austenitic first. In some cases the ASTM
reference is to the content rather than the classification. In those cases
the basic content is listed (i.e., iron-chromium-nickel).
Specifications by type are listed by the types generally in use and do
not cover all the stainless steel types that are available.

SELECTED STAINLESS STEEL TYPES AND APPLICABLE SPECIFICATIONS
Unified Numbering System: Included in the tables are six-character designations under the Unified Numbering System (UNS) for the AISI numbered stainless
steels. The Unified Numbering System originated through a cooperative effort of the American Society for Testing and Materials and the Society of Automotive
Engineers, and UNS numbers apply to all metals and alloys. All stainless steels will be identified under this system with the letter “S” followed by five digits.
