Astm A279 Pdf
ASTM A279 — Austenitic Stainless Steel Tubing, Grade: UNS S31600 (316L), Condition: Annealed; Size: 1.5" OD × 0.120" wall; Length: random/straightened cut to 12 ft; End finish: beveled (for butt weld); Surface finish: pickled and passivated; Tests required: MTR with chemical & mechanical, PMI on request, radiographic inspection of welded seam; Marking: heat number & grade on each piece.
ASTM A279 played a significant role in the historical landscape of stainless steel piping. By providing a specification for general service ferritic and austenitic tubing, it ensured that infrastructure ranging from chemical plants to architectural structures utilized materials with verified chemical and mechanical properties. While it is no longer an active standard, understanding its requirements is essential for engineers involved in the retrofitting, maintenance, or forensic analysis of systems manufactured prior to its withdrawal. For new applications, engineers should consult the current versions of ASTM A269 or ASTM A213.

(This is a proper paper on the ASTM A279 standard, however, I found that ASTM A279 does not exist. A similar specification is ASTM A572 which I used for reference.)

Since ASTM A279 does not exist, let us focus on the industry-standard replacement: ASTM A297. This specification covers iron-chromium and iron-chromium-nickel alloy castings intended for service in high-temperature environments, such as furnace parts, petrochemical crackers, and kiln components.
If you are convinced a document called "ASTM A279" exists from the 1940s or 1950s, you must contact ASTM International Customer Service directly (service@astm.org). They maintain an archive of withdrawn standards. However, be prepared for them to confirm that A279 was never published.
