1.1 This specification covers high-strength, low-alloy structural steel plates produced by quenching and tempering.

ASTM standard A279 is no longer an active document. An "A 279" entry in the ASTM Standard List is clearly marked with the status: "Replaced by G 31" and listed among other testing standards that are no longer in active use. The all-standards.com listing explicitly describes it as "Withdrawn Withdrawn 1945: Method of Total Immersion Corrosion Test of Stainless Steels".

and replaced. In modern engineering and metallurgy, the following standards are now used to fulfill the requirements previously covered by A279: Astm A279 Pdf

Before its withdrawal, ASTM A279 provided a standardized procedure for evaluating the resistance of stainless steels to corrosion when completely submerged in a liquid medium. The goal was to provide a controlled environment to measure weight loss and observe pitting or other forms of surface degradation. Key Aspects of the Former Standard

The primary metric, calculated as average corrosion rate (e.g., mils per year or mm/year). The all-standards

While the original standard is no longer active, the term "ASTM A279" is frequently used by manufacturers and suppliers to refer to high-precision stainless steel products—particularly —often in conjunction with active standards like ASTM A276 (for bars and shapes) or ASTM A269 (for tubing). Core Overview of the Specification

: Covers seamless and welded austenitic stainless steel tubing for general corrosion-resisting and low- or high-temperature service. The goal was to provide a controlled environment

Exercise extreme caution with websites that offer free PDF downloads of ASTM A279. Many of these sites host low-quality scans with missing pages or poor legibility. More importantly, they may violate copyright and could contain malware. The best practice is to always obtain standards through official channels.

7.1 : The plates shall conform to the requirements for tensile properties presented in Table 2.
