Withdrawn (Often listed with a date like 1945 or later, with no active replacement under the exact same designation).

While this standard has been largely superseded or withdrawn in favor of more modern methodologies, understanding its principles is crucial for auditing legacy projects, studying corrosion history, and understanding the basics of immersion testing. What is ASTM A279?

The only version of the standard ever issued was , which was officially published on January 1, 1963 . This single edition remains the definitive version of the standard. Astm A279 Pdf

The standard dictates the exact percentage of elements such as Chromium, Nickel, Molybdenum, and Carbon. For example, a common grade like 304 stainless under this specification must typically contain between 17.5% and 19.5% Chromium and 8.0% to 10.5% Nickel to ensure the formation of the passive oxide layer that prevents rust.

After digging through historical cross-references, you realize that A279 was a specification for Total Immersion Corrosion Test of Stainless Steels . Withdrawn (Often listed with a date like 1945

If you were hoping for "ASTM A279 Grade HF" or "HT," you now know the correct specification: . The only version of the standard ever issued

In conclusion, the ASTM A279 PDF is a critical document in the steel industry, providing a standardized set of requirements for stainless steel and heat-resisting steel products. The standard ensures that steel products meet the required quality, safety, and performance standards, and it has a wide range of applications in various industries. Manufacturers, suppliers, and buyers of steel products must ensure that they have access to the ASTM A279 PDF and comply with its requirements to ensure the quality and safety of their products.

While "ASTM A279" is frequently listed by suppliers alongside common standards like

If you are looking for this "story" because you actually need to replace a part or verify a material, the plot has moved on. The "spirit" of A279—the testing of how stainless steel stands up to being completely dunked in corrosive liquid—was absorbed into a much more famous standard:

In the demanding world of materials engineering, selecting the right metal for corrosive environments is critical. Historically, the standard, formally known as the "Method of Total Immersion Corrosion Test of Stainless Steels," served as a foundational guideline for evaluating how stainless steels behave when completely submerged in a corrosive liquid.
