New ASTM A967/A967M 2013 Edition on Chemical Passivation Treatments for Stainless Steel Parts

ASTM A967/A967M 2013 Edition has just been released and is available from Document Center Inc. in either paper or pdf format.  Titled “Standard Specification for Chemical Passivation Treatments for Stainless Steel Parts,” the new revision is one of our go-to documents for chemical passivation.  It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts.

Included are the following tests:

  1. Practice AWater Immersion Test,
  2. Practice BHigh Humidity Test,
  3. Practice CSalt Spray Test,
  4. Practice DCopper Sulfate Test,
  5. Practice EPotassium Ferricyanide–Nitric Acid Test, and
  6. Practice FDamp Cloth Test.

This practice references QQ-P-35 (later renumbered AMS-QQ-P-35 and then withdrawn in favor of AMS-2700), another major passivation document.  The ASTM A967/A967-13 replaces ASTM A967/A967M-05 which is now obsolete.

Changes to the new 2013 Edition of A967/A967M can be found in the following areas:  Section 1.5 (changed to combined Metric/US units), Revised Section 4.1 and added Section 4.3, Added Notes 2 and 3 to Sections 6 and 7, Revised Section 13.3, Combined Sections 14 through 19 into a new Section 14, Revised Section 22.1 (Now numbered 17.1) and added Section 17.2, and Added Sections X1.3.2-X1.3.4 and X1.12 to the Appendix.

Whatever happened to QQ-P-35, Passivation Treatments for Corrosion Resistant Steel?

QQ-P-35, “Passivation Treatments for Corrosion Resistant Steel,” is another government document that was cancelled due to the implementation of the National Technology Transfer and Advancement Act in the mid-1990’s.  The public law, known as NTTAA, directs Federal Agencies to use technical standards “that are developed or adopted by voluntary consensus standards bodies.”  Since QQ-P-35 was a Federal Specification it was an obvious candidate for replacement with a U.S. industry standard.

QQ-P-35 was originally issued in July 1963.  Revision C from 1988 was withdrawn by Cancellation Notice 3 on 9/11/1998.  The Cancellation Notice specifies that QQ-P-35 can be replaced by both ASTM A967 and AMS QQ-P-35.  This shows the use of two types of replacement documents:  1) a pre-existing standard (ASTM A967) and 2) a standard that is a republication of the withdrawn government to migrate the caretaking of the standard from a government organization to an industry one (AMS QQ-P-35).

The other interesting point about this particular superseding history is that seven years after the AMS republication of the specification, the document (AMS QQ-P-35) was itself cancelled in favor of another AMS standard, AMS 2700.  This actually was possible because of government participation in the committee that writes the AMS 2700 standard.  With the publication of Revision B in February 2004, issues in the previous edition of the document that made it unsuitable for government usage were resolved.  Thus the final migration to an industry standard was made possible.

So now, the current replacements for QQ-P-35 are the ASTM A967, “Standard Specification for Chemical Passivation Treatments for Stainless Steel Parts,” and AMS 2700, “Passivation of Corrosion Resistant Steels.”

In actuality, the number of government documents that were republished in this way in order to facilitate migration to industry-sponsored standards is relatively small.  It was certainly made possible because the federal level government documentation is not covered by copyright.  And by this time, many of those republications have been revised or withdrawn as well.

Should you have an obsolete document and need to know what it was replaced by, contact Document Center staff by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’ve been keeping records on standards since 1982 and for many items, our history information goes back much further.

All current Federal Specifications can be purchased at our website, www.document-center.com.  Many obsolete revisions are available, along with the documents that have replaced them.

AMS 2700 Revision E just released on Passivation of Corrosion Resistant Steels

AMS 2700 Revision E, “Passivation of Corrosion Resistant Steels,” has just been released.  The new edition replaces AMS 2700 Revision D which was released back in July of this year.  The specification covers the requirements for a process to assure removal of free iron or other less noble contaminants from the surfaces of corrosion resistant steel parts.

There are two passivation methods covered by AMS 2700E — Passivation in Nitric Acid and Passivation in Citric Acid.

For the first method, 8 types may be specified:

  • Low Temperature Nitric Acid with Sodium Dichromate
  • Medium Temperature Nitric Acid with Sodium Dichromate
  • High Temperature Nitric Acid with Sodium Dichromate
  • 40% Nitric Acid for Free Machining Steels
  • Anodic, for High Carbon Martensitic Steels
  • Low Temperature Nitric Acid
  • Medium Temperature Nitric Acid
  • Medium Temperature, Nigh Nitric Acid Concentration

The processes defined in this specification have been used typically to dissolve metallic elements from the surfaces of corrosion resistant steels to improve their corrosion resistance, but usage is not limited to such applications.

The new AMS 2700 and all SAE Standards may be purchased from Document Center Inc. on our website, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We have many obsolete SAE documents available, with extensive information on the revision history on the website.

New AMS 2700 Revision D on Passivation of Corrosion Resistant Steels just released

There’s a new AMS 2700 Revision D available.  Titled “Passivation of Corrosion Resistant Steels,” the document covers the requirements for a process to assure removal of free iron or other less noble contaminants from the surfaces of corrosion resistant steel parts.

The document is part of the AMS (Aerospace Material Specifications) series.  The new edition was generated to correct errors reported by users.  It replaces the AMS 2700 Revision C, which is now obsolete.  It is 15 pages in length and is dated 7/2011.

The processes used in this specification are usually used to dissolve tramp metallic elements from the surfaces of corrosion resistant steels to improve their corrosion resistance.  However, other uses for the specification are also acceptable.

This specification and all AMS standards, including obsolete revision levels, are available from Document Center Inc.  Use our website, www.document-center.com, or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We do business internationally and can help you with any standards issues you may have.
