If you are auditing a legacy blueprint or contract that specifies an ASTM A279 testing protocol, you will need to reference modern equivalents to fulfill quality assurance criteria. The primary standards used today include:
The standard allows for various corrosive solutions depending on the intended application of the steel. Common testing solutions include: Sulfuric acid solutions Hydrochloric acid mixtures Organic acids at elevated temperatures 3. Apparatus Setup
Found in pulp and paper processing, water softener tanks, and chemical processing equipment. Astm A279 Pdf
The method was intended for rather than predicting the exact service life of a component. It helped engineers choose between different alloys (e.g., 304 vs. 316 stainless steel) based on their performance in a simulated environment. Key Elements of the ASTM A279 Test Method
One of the biggest challenges with "A279" is that it is often confused with other, more common ASTM standards. This leads to significant errors in technical specifications and procurement documents.
(officially ASTM A279-73a, Method of Total Immersion Corrosion Test of Stainless Steels ) was a technical standard published by ASTM International . It provided a standardized method for evaluating the corrosion resistance of stainless steel alloys by immersing them in a liquid medium under controlled conditions. The Purpose of the Test The primary aim of ASTM A279 was to:

ASTM A479 Stainless Steel Bars and Shapes for Use in Boilers
Because of its roots in corrosion testing and its association with high-grade stainless alloys, materials meeting these criteria are used in specialized sectors :
No. ASME SA-279 is a carbon steel forging specification that was withdrawn in 1997 (replaced by ASME SA-105). That is for pipe flanges and fittings, not castings. Again, irrelevant to heat-resistant alloys.
The test required a clear description of the liquid solution, including chemical composition, concentration, pH, and temperature. 4. Duration The primary standards used today include: The standard
Standard Practice for Preparing, Cleaning, and Evaluating Corrosion Test Specimens.
Usually measured on the Brinell or Rockwell scales (e.g., 15–20 HRC for annealed 304).
Total immersion means the test specimen is completely submerged in the test solution. This ensures uniform contact with the corrosive agent.
