Astm A279 Pdf
: Generally measured via Brinell or Rockwell scales (e.g., 160-190 Brinell). Applications & Industries
: Used specifically for pitting and crevice corrosion resistance using ferric chloride solutions. Accessing the Document
: It was officially replaced by ASTM G31 , the Standard Guide for Laboratory Immersion Corrosion Testing of Metals.
Many engineers incorrectly substitute ASTM A351 (stainless steel castings) for A297. 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. Astm A279 Pdf
The surface is finished using specific abrasive papers to remove scale, oils, and pre-existing oxidation.
: Utilized primarily for applications requiring high hardness and moderate corrosion resistance, capable of being heat-treated (e.g., Grade 410).
It established procedures for the "Total Immersion Corrosion Test" specifically for stainless steels : Generally measured via Brinell or Rockwell scales (e
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 Specifically, ASTM A279's functions were largely absorbed or superseded by
When old engineering specifications demand compliance with ASTM A279 corrosion testing, they are typically referring to high-performance . These materials are widely distributed by metal suppliers today under updated structural and chemical standards: ASTM A279 Stainless Steel Tubes
It wasn't a material at all; it was a testing method . Even more importantly, it was withdrawn in 1975 . The Modern Successor Substitution will cause catastrophic furnace failure
(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 International officially ASTM A279. The exact year of withdrawal varies in records, but the standard is no longer recognized for new construction in most jurisdictions.
