: This is the most common standard for detecting susceptibility to intergranular attack in austenitic stainless steels (often called the "Huey Test" or "Streicher Test").
The test is conducted at a specified, constant temperature (often boiling or a tightly controlled ambient temperature). Exposure times typically range from 24 to 48 hours per cycle, often repeated over multiple periods to identify changing corrosion rates over time. 5. Post-Test Evaluation
A significant source of confusion comes from the fact that in the industrial marketplace, the designation "ASTM A279" is frequently and incorrectly applied to describe stainless steel bar products.
The primary objective of the ASTM A279 specification is to maintain uniform manufacturing parameters for stainless steel materials, focusing largely on architectural, general structural, and highly corrosive application environments. The document covers several metallurgical structures, including: Astm A279 Pdf
In modern industrial procurement, engineers and procurement managers searching for an "ASTM A279 PDF" are typically looking for updated, active technical documents that govern stainless steel corrosion testing, piping, or tubing. Over time, supply chains have evolved, and the testing methodologies originally outlined in A279 have been absorbed or replaced by modern standards like (intergranular corrosion testing) and various structural tubing specifications.
Withdrawn (Historical Standard)
Because ASTM A279 is a "Withdrawn" standard, it is generally not available for free as a PDF on the ASTM website : This is the most common standard for
Measures the exact mass loss of a specimen over a fixed period.
- Standard Specification for Stainless Steel Bars and Shapes (the most commonly used specification for stainless steel bars in general applications)
Used to calculate the uniform corrosion rate (e.g., millimeters per year, mm/y, or mils per year, mpy). millimeters per year
This comprehensive technical guide breaks down the core sections found within the standard ASTM A279 document. It details the metallurgy, processing options, and core testing specifications required to maintain strict compliance. 1. Scope and Structural Overview
