: Hexagonal and round bars used in saltwater-resistant hardware.
Although it is obsolete, ASTM A279 still holds relevance in certain contexts. Its legacy persists for several reasons:
A flask or container, often equipped with a reflux condenser to prevent solution loss due to evaporation.
Comprehensive Guide to ASTM A279: Standard Specification for Total Immersion Corrosion Test of Stainless Steels Astm A279 Pdf
: For historical standards like ASTM A279-63, some archival libraries and standards history collections may maintain physical copies available for research purposes.
Although the ASTM A279 PDF might be hard to locate, the core methodology involves several critical steps: 1. Specimen Preparation
Official records also indicate that the combined designation "ASTM A279/A279M" does not exist . The metric companion standard, A279M, was never developed, further evidence that A279 was an early, isolated test method that was not integrated into ASTM's modern dual-unit system. : Hexagonal and round bars used in saltwater-resistant
The historical ASTM A279 PDF detailed the rigid laboratory steps required to execute a total immersion test. The objective was simple: determine the mass loss and pitting characteristics of stainless steel when fully submerged in an aggressive solution.
When looking for an ASTM A279 PDF or evaluating materials labeled under this lineage, engineers must understand its historical context, why it was replaced, and how modern stainless steel tubing or bar specifications (such as ASTM A269 or ASTM A479) handle its original testing intents. Historical Overview & Status of ASTM A279
After digging through historical cross-references, you realize that A279 was a specification for Total Immersion Corrosion Test of Stainless Steels . Comprehensive Guide to ASTM A279: Standard Specification for
Provides a standardized baseline to compare different stainless steel grades (e.g., 304 vs. 316L) under identical conditions. Importance of the Total Immersion Test
By 1945, ASTM withdrew the isolated A279 document. The testing guidelines were synthesized into comprehensive, modern testing practices. These include ASTM A262 (for detecting susceptibility to intergranular attack in austenitic stainless steels) and broader mechanical/chemical specification books.
