The ASTM A279 specification covered both seamless and welded tubing.
The standard encompassed several grades of ferritic and austenitic stainless steel, allowing for selection based on specific corrosion resistance and mechanical needs. The tubing was typically supplied in the annealed condition, though other heat treatments were permitted if specified.
Title: Standard Specification for Seamless and Welded Ferritic and Austenitic Stainless Steel Tubing for General Service Astm A279 Pdf
Designation: ASTM A279 / A279M – 18
Status: Withdrawn (Historical Standard)
ASTM A279 was a standard developed by ASTM International (formerly the American Society for Testing and Materials) to cover a broad range of stainless steel tubing. Unlike standards specifically tailored for high-pressure boilers (e.g., ASTM A213) or sanitary applications (e.g., ASTM A270), ASTM A279 provided guidelines for "General Service."
This classification meant the tubing was suitable for applications involving structural supports, mechanical components, and general fluid transport where standard corrosion resistance was required, but the extreme conditions of nuclear or high-pressure boiler applications were absent. The standard has since been withdrawn by ASTM International, meaning it is no longer actively maintained or updated. It is often replaced by more specific standards or absorbed into broader specifications. However, understanding A279 remains vital for maintenance of older infrastructure and historical engineering analysis. The ASTM A279 specification covered both seamless and
Every length of tubing was required to undergo a hydrostatic test. The tube was pressurized internally with water to a specified pressure (often calculated based on the wall thickness and allowable fiber stress) and held for a set duration to check for leaks or weaknesses.
ASTM A279 (often referenced in full as ASTM A279/A279M) is a standard specification established by ASTM International, formerly known as the American Society for Testing and Materials. This standard covers the requirements for stainless steel bars, shapes, and forgings intended for use in pressure vessels and general applications. The standard encompassed several grades of ferritic and
While the standard itself is a technical document, the search for an "ASTM A279 PDF" usually indicates a need to understand the material properties, chemical composition, and industrial applications of these steel grades.
Since ASTM A279 does not exist, let us focus on the industry-standard replacement: ASTM A297. This specification covers iron-chromium and iron-chromium-nickel alloy castings intended for service in high-temperature environments, such as furnace parts, petrochemical crackers, and kiln components.
