If you are looking for specific, in-service corrosion testing rather than laboratory immersion, are you looking for: ASTM G48 (Pitting and Crevice Corrosion) ASTM A262 (Intergranular Attack in Stainless Steels)

1.1 This specification covers high-strength, low-alloy structural steel plates produced by quenching and tempering.

: Requirements for calculating corrosion rates (usually in mils per year or millimeters per year) based on mass loss. Current Standard: ASTM G31

Specimens were cleaned to remove any foreign contaminants and weighed to a precise degree.

These specifications cover the full range of stainless steel grades including austenitic (304, 316L), ferritic (430), martensitic (410, 420), and precipitation-hardening grades, with comprehensive requirements for chemical composition, mechanical properties, tolerances, and surface finish.

The most frequent mix-up is between A279 and A276 . ASTM A276 is a widely used specification for stainless steel bars and shapes . It sets the chemical, mechanical, and dimensional requirements for everything from round bars to hexagons and angles. However, many suppliers and catalogs incorrectly list A276/A279 together. For example, some bar product listings say they "conform to ASTM A276/A279 standards". This is a technical error because A279 is a corrosion test method, not a material specification. A276 and A279 are completely different types of documents that serve different purposes. If you are specifying stainless steel bars, the correct standard is ASTM A276 .

ASTM A279 was an ASTM International standard titled . It was later withdrawn and replaced by ASTM G31 , which currently governs the standard practice for laboratory immersion corrosion testing of metals. If you need the specific historical text for

It established procedures for the "Total Immersion Corrosion Test" specifically for stainless steels

It is important not to confuse ASTM A279 with other similar specifications:

Engineers use this data to compare different stainless steel grades (e.g., 304 vs. 316) to choose the most cost-effective option for a specific environment. Alternative and Modern Standards

Despite its withdrawal, some specialty supply houses and manufacturers occasionally reference "A279" colloquially alongside stainless steel welded and seamless tubing grades (such as TP304, TP316, and TP321) to indicate that materials have undergone or can withstand comprehensive immersion corrosion evaluation.
