Understanding the full scope of ASTM A279 helps industries select the right materials, ensure regulatory compliance, and prevent catastrophic material failures. What is ASTM A279?
ASTM A279, formerly used for total immersion corrosion testing of stainless steels, was withdrawn in 1945 and replaced by ASTM G31. While sometimes mistakenly listed in modern catalogs, active, relevant standards for stainless steel testing include ASTM G31 for immersion and ASTM A269 or A479 for materials.

: To determine the suitability of specific stainless steel grades for service in corrosive chemical environments. Methodology
As shown in the search results, there is also an AASHTO M 279 standard for metallic-coated steel wire fence fabric. This is a completely separate standard from a different organization (the American Association of State Highway and Transportation Officials) that happens to share a similar number.

The current, preferred standard for laboratory immersion corrosion testing.
Corrosive agents (often acidic or saline solutions) were strictly controlled for temperature, aeration, and concentration.
: Some third-party resellers still offer the withdrawn ASTM A279-63 standard for purchase, though these are typically reproductions of the original document rather than current, active standards. These sellers often operate in legal gray areas and may not provide authentic, verified copies of the original standard.
Despite its withdrawal, some specialty supply houses and manufacturers occasionally reference "A279" colloquially alongside stainless steel welded and seamless tubing grades (such as TP304, TP316, and TP321) to indicate that materials have undergone or can withstand comprehensive immersion corrosion evaluation. Understanding the Total Immersion Test Method Understanding the full scope of ASTM A279 helps
Specimen blanks are degreased, washed in distilled water, dried, and weighed on an analytical balance to the nearest milligram. 2. Test Solution Selection
: Require normalizing and tempering or liquid quenching to unlock specified hardness levels. Surface Finish Varieties
ASTM A279 specified tolerances for dimensions to ensure interchangeability and fit:
: The general industry standard for laboratory immersion corrosion testing. Methodology As shown in the search results, there
Samples were carefully cut, machined, and polished to eliminate surface anomalies or scale from manufacturing.
The ASTM A279 PDF has a wide range of applications in the steel industry, including:
When sourcing or purchasing the official , users gain access to the precise engineering specifications required to build a compliant testing apparatus. The document is structured into several definitive sections:
Because ASTM A279 is a "Withdrawn" standard, it is generally not available for free as a PDF on the ASTM website
