ASTM A279 was a historical, officially withdrawn standard (replaced by ASTM G31) that provided methodologies for the total immersion corrosion testing of stainless steels. Although obsolete as a standard, its, procedures for calculating corrosion rates via mass loss remain relevant, and the designation is occasionally utilized in industrial product catalogs for austenitic and high-temperature steel grades.

I found that ASTM A279 does not exist.

If you are looking for information on a specific standard, I suggest you:

ASTM A279 is a technical standard that covers stainless steel tubes, including seamless and welded varieties. These tubes are engineered for precision and high resistance to abrasion and rust, making them a staple in environments requiring durable and low-maintenance materials.

While often linked to bar specifications like ASTM A276 (general service bars) and ASTM A479 (boiler and pressure vessel bars), ASTM A279 focuses on tubular products used in specialized industrial and commercial settings. Material Grades and Chemical Composition

Stainless steel tubes under this specification are available in multiple grades to suit different corrosive environments. Common grades include:

Austenitic Grades (300 Series): 304, 304L, 316, 316L, 321, and 347. These are known for high ductility and excellent corrosion resistance.

Martensitic & Ferritic Grades: 410, 446, and others, often used for their magnetic properties and higher hardness.

Exotic & Duplex Grades: 904L and other high-alloy variations for extreme acidic or high-chloride environments. Typical Composition Example (Grade 304/304L) Content (%) Chromium (Cr) 17.5 – 19.5 Nickel (Ni) 8.0 – 10.5 Carbon (C) ≤ 0.08 (304) / ≤ 0.03 (304L) Iron (Fe) Mechanical and Physical Properties

The standard ensures that materials meet specific mechanical benchmarks through rigorous testing, including tensile strength, yield strength, and hardness.

Tensile Strength: Typically ranges from 515 MPa to 675 MPa depending on the grade and heat treatment.

Yield Strength: Generally starts at 205 MPa for annealed austenitic grades.

Hardness: Usually measured on the Brinell or Rockwell scales (e.g., 15–20 HRC for annealed 304).

Corrosion Resistance: Highly resistant to industrial acids, saline solutions, and high temperatures. Applications of ASTM A279 Products

Thanks to their sturdy construction and aesthetic appeal, these stainless steel tubes and related products are used across various sectors:

Food & Medical: Ideal for kitchens, beverage storage, and surgical tools due to their hygienic, non-porous surfaces.

Infrastructure: Used in handrails, support frameworks, and architectural components.

Energy & Marine: Applied in water infrastructure, marine equipment, and energy systems where chloride resistance is critical. To ensure the material met the demands of

Industrial: Found in pulp and paper processing, water softener tanks, and chemical processing equipment.

ASTM A479 Stainless Steel Bars and Shapes for Use in Boilers

ASTM A279 is a discontinued historical standard that was formerly used for the Total Immersion Corrosion Test of Stainless Steels . It was officially withdrawn by ASTM International in 1975 and replaced by more modern testing protocols. Overview of ASTM A279

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

: To determine the suitability of specific stainless steel grades for service in corrosive chemical environments. Methodology

: It involved immersing polished or prepared metal coupons in a specified boiling solution (often nitric acid) for set periods, typically five 48-hour periods. Evaluation

: Results were calculated based on the corrosion rate, usually expressed in inches per month (ipm) or millimeters per year (mm/y), derived from the weight loss of the specimen. Why was it Withdrawn?

The standard was retired because the industry moved toward more comprehensive and specialized testing methods. Specifically, ASTM A279's functions were largely absorbed or superseded by

, which is the current "Standard Guide for Laboratory Immersion Corrosion Testing of Metals." Current Alternatives for Stainless Steel Testing

If you are looking for modern standards to replace the requirements once covered by A279, consider the following:

: The primary guide for laboratory immersion corrosion testing for all metals, including stainless steel.

: This is the most common standard for detecting susceptibility to intergranular attack in austenitic stainless steels (often called the "Huey Test" or "Streicher Test").

: Used specifically for pitting and crevice corrosion resistance using ferric chloride solutions. Accessing the Document

Because ASTM A279 is a "Withdrawn" standard, it is generally not available for free as a PDF on the ASTM website

. However, you can usually purchase "Historical Versions" directly from the ASTM International website

if you need it for forensic engineering or to fulfill legacy contract requirements. like ASTM G31 or A262?

Look closely at your keyboard or your old notes. The numbers "7" and "9" are adjacent. It is highly plausible that a decade ago, someone mis-typed "ASTM A297" as "ASTM A279," and that incorrect reference has since propagated through old forum posts, unofficial spec sheets, and even some procurement documents.

Therefore, any search for an "ASTM A279 PDF" should immediately redirect to obtaining the ASTM A297 PDF.

A: No. The ASTM standard for alloy steel forgings is A279? Wait, no—that is A290 (Steel Forge Rings) or A788 (Forgings). The US War Department (1946) listed a "Specification A279" for manganese-silicon electrode coatings, but that was a Military Specification, not an ASTM. It was withdrawn in 1955. Do not confuse military specs with ASTM.

A: Politely ask them to verify the number. Provide them this article. Explain that ASTM A279 is not a recognized standard. Then, ask which heat-resistant property they need: chromium content, nickel content, or high-temperature creep strength. Match that to ASTM A297, A297/A297M, or even the equivalent ISO 11973.

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.

This paper provides a comprehensive analysis and summary of ASTM A279, the historical Standard Specification for Seamless and Welded Ferritic and Austenitic Stainless Steel Tubing for General Service. This standard was historically utilized to define the requirements for stainless steel tubes used in structural, mechanical, and general corrosive environments where high temperatures and pressures were not the primary concern. This document outlines the scope, chemical composition, mechanical properties, and testing methodologies defined within the standard, serving as a reference for engineers dealing with legacy systems or material substitution.
