: Purchase PDF downloads directly from the official source. This ensures you receive the complete, most current version of the standard with all corrections and updates.

While the standard is withdrawn, ASTM International or its authorized resellers may still offer it for historical reference. This is the only legal and reliable way to get an authentic copy, as free downloads from unofficial sources are often illegal, low-quality, or incomplete.

Because of its roots in corrosion testing and its association with high-grade stainless alloys, materials meeting these criteria are used in specialized sectors :

: Some third-party resellers still offer the withdrawn ASTM A279-63 standard for purchase, though these are typically reproductions of the original document rather than current, active standards. These sellers often operate in legal gray areas and may not provide authentic, verified copies of the original standard. Astm A279 Pdf

Looking for pitting, crevice corrosion, or color changes. Why Was ASTM A279 Withdrawn?

The ASTM A279 standard was established in the early era of commercial stainless steel manufacturing. Its primary function was to codify the . This framework evaluated how various iron-chromium and iron-chromium-nickel alloys reacted when completely submerged in volatile acid or saline solutions.

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. : Purchase PDF downloads directly from the official source

Designing reactors and storage vessels for volatile acids.

Used to prepare the stainless steel surface to maximize its inherent corrosion resistance. Key Takeaways for Accessing "ASTM A279 PDF"

Applied in water infrastructure, marine equipment, and energy systems where chloride resistance is critical. This is the only legal and reliable way

ASTM A279 helped establish early standardized practices for immersion corrosion testing. Its development was part of a broader effort across the mid-20th century to standardize testing procedures for metallic materials, paving the way for more comprehensive and robust standards like G31.

The standard, historically known as the Method of Total Immersion Corrosion Test of Stainless Steels , is a foundational, historically significant testing standard published by the American Society for Testing and Materials (ASTM). Though withdrawn by ASTM in 1945 , the document remains highly searched as an "ASTM A279 PDF" due to historical project audits, legacy industrial blueprints, and its direct evolution into modern corrosion standards like ASTM G31.

Defines the types of stainless steel covered and the limitations of the test.

Products associated with this designation must meet strict chemical requirements to ensure performance in harsh environments. Typical Range (Austenitic Grades) 16.0% – 20.0% (provides corrosion resistance) Nickel (Ni) 8.0% – 14.0% (improves toughness and ductility) Molybdenum (Mo) 2.0% – 3.0% (added in Grade 316 for pitting resistance) Carbon (C) 0.03% – 0.08% max (lower in "L" grades for weldability) Mechanical Benchmarks (Annealed State): Tensile Strength : Often exceeds 75-90 ksi. Yield Strength : Typically starts at 30-45 ksi.
