The ASTM A279 PDF can be obtained through various channels: It was later withdrawn and replaced by ASTM
If you were looking for a specific alloy under the phantom "A279," it is almost certainly one of these common grades from A297:
ASTM A279, formerly titled the , is a historically significant standard for evaluating how stainless steel reacts to corrosive aqueous solutions. 🛠️ Status and Modern Replacement Status : This standard is withdrawn and no longer active.
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 It was later withdrawn and replaced by ASTM G31 , which currently governs the standard practice for laboratory immersion corrosion testing of metals.
