This is a new page for displaying documents. The first time a document is loaded will take a little longer than it will for the next person so please be patient if it takes time. It will be much faster once all the documents have been converted. This will also allow these documents to display on devices without pdf viewers specifically mobile devices. Please email me at "L-36" dot COM if you notice any strange behavior. This is part of the Google requirement that all web pages be "mobile friendly". This is an effort that takes quite a bit of time and as it is just me and I would rather be sailing...

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.

ACKNOWLEDGMENT
  An original version was initially published by the Committee of
Stainless Steel Producers, American Iron and Steel Institute (AISI),
Washington, D.C., and was used, with thanks, as a basis for this
updated handbook.
  The 2001 Annual Book of ASTM Standards, Sections 1 and 13 were
used as the reference base for listed ASTM 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," available from the Specialty
Steel Industry of North America (SSINA).
  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.

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.

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
