It is important not to confuse ASTM A279 with other similar specifications:
ASTM A279 is a withdrawn standard that was formerly titled "Standard Test Method for Total Immersion Corrosion Test of Stainless Steels."
Because the standard has been officially withdrawn by ASTM International without a direct replacement, it is no longer available as an active technical document in their current catalog. Key Details about ASTM A279
Purpose: It provided a procedure for conducting total immersion corrosion tests on stainless steels to determine their resistance to various corrosive environments.
Withdrawal Status: It was discontinued in the late 20th century. In many cases, corrosion testing for stainless steels shifted toward more specific standards like ASTM G31 (Standard Guide for Laboratory Immersion Corrosion Testing of Metals). Current Alternatives:
ASTM G31: The general industry standard for laboratory immersion corrosion testing. Astm A279 Pdf
ASTM A262: Specifically covers detecting susceptibility to intergranular attack in austenitic stainless steels. How to Access the Text
Since ASTM standards are copyrighted, the full text cannot be legally reproduced here. If you need the specific historical text for a legacy project or legal compliance, you can:
ASTM Historical Custom Collections: Purchase a PDF copy of the historical version directly from the ASTM International website.
Technical Libraries: University engineering libraries or large municipal libraries often keep physical archives of older ASTM "Book of Standards" volumes.
ASTM A279 was the Standard Specification for Total Immersion Corrosion Test of Stainless Steels.
It is important to note that this standard was withdrawn in 1991 and replaced by ASTM G31, the Standard Guide for Laboratory Immersion Corrosion Testing of Metals. Summary of the Withdrawn ASTM A279 ASTM A279 bars can be supplied in various
The original paper focused on a standardized procedure for evaluating the corrosion resistance of stainless steels when completely submerged in a corrosive liquid. Key elements included:
Scope: Primarily covered the apparatus, specimen preparation, and testing procedures for total immersion.
Methodology: It defined how to maintain consistent temperature, aeration, and solution volume-to-specimen area ratios to ensure reproducible results.
Reporting: Requirements for calculating corrosion rates (usually in mils per year or millimeters per year) based on mass loss. Current Standard: ASTM G31
If you are looking for modern testing protocols, you should refer to ASTM G31. This updated guide provides:
Broader Application: It covers all metals, not just stainless steels. Astm A279 Pdf
Controlled Variables: Detailed guidance on solution composition, velocity, and duration of the test.
Data Interpretation: Standardized formulas for weight loss analysis. How to Access the PDF
Because ASTM standards are copyrighted materials, they are typically not available for free legally. You can obtain the current replacement (G31) or historical versions of A279 through:
ASTM International: The official ASTM website allows you to purchase and download PDFs. Standards Aggregators: Sites like IHS Markit or SAI Global.
Academic Libraries: If you are a student or researcher, your institution may provide access via the ASTM Compass database.
Many engineers incorrectly substitute ASTM A351 (stainless steel castings) for A297. Do not do this. A351 is for corrosion resistance at room temperature. A297 is designed for oxidation and creep resistance at 1800°F+. Substitution will cause catastrophic furnace failure.
