Astm A279 Pdf ⚡ Secure
Standardization through ASTM International provides a global language for material quality, ensuring that engineers can specify A269 tubing with confidence in its safety and performance under corrosive conditions.
Standard Specification for Seamless and Welded Ferritic and Austenitic Stainless Steel Tubing for General Service
The term historically refers to an early standard designated by the American Society for Testing and Materials. Originally titled the Method of Total Immersion Corrosion Test of Stainless Steels , it was officially withdrawn by the ASTM committee in 1945.
If you were hoping for "ASTM A279 Grade HF" or "HT," you now know the correct specification: . Astm A279 Pdf
Total immersion tests provide valuable data that lab-based tests often miss:
Lists related ASTM standards required for absolute compliance.
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. If you were hoping for "ASTM A279 Grade
Generally starts at 205 MPa for annealed austenitic grades.
It mimics applications like heat exchangers, piping systems, and storage tanks where materials are fully submerged.

Although it is obsolete, ASTM A279 still holds relevance in certain contexts. Its legacy persists for several reasons:
Tensile tests were performed on specimens taken from the tube to verify strength and elongation. Hardness tests were also conducted on representative samples.
ASTM A279, formerly used for total immersion corrosion testing of stainless steels, was withdrawn in 1945 and replaced by ASTM G31. While sometimes mistakenly listed in modern catalogs, active, relevant standards for stainless steel testing include ASTM G31 for immersion and ASTM A269 or A479 for materials.

The test runs for a set period, often long enough to allow for steady-state corrosion rates to be established. 4. Post-Test Evaluation
