No. ASME SA-279 is a carbon steel forging specification that was withdrawn in 1997 (replaced by ASME SA-105). That is for pipe flanges and fittings, not castings. Again, irrelevant to heat-resistant alloys.
The general thinning of material across the surface. Astm A279 Pdf
As shown in the search results, there is also an AASHTO M 279 standard for metallic-coated steel wire fence fabric. This is a completely separate standard from a different organization (the American Association of State Highway and Transportation Officials) that happens to share a similar number. Again, irrelevant to heat-resistant alloys
Chemical composition is the baseline requirement dictated in the ASTM A279 PDF. The exact material performance depends heavily on the precise balancing of primary and trace elements. Below is a comparative look at the typical alloying elements specified for key grades governed under this and related standard families: Austenitic (e.g., 304/316) Martensitic (e.g., 410) Structural Impact 17.0% – 20.0% 11.5% – 13.5% Forms the passive oxide layer to prevent rust. Nickel (Ni) 8.0% – 13.0% Stabilizes the austenitic phase; enhances toughness. Molybdenum (Mo) 2.0% – 3.0% (in 316) Increases localized pitting resistance in chloride zones. Carbon (C) ≤is less than or equal to ≤is less than or equal to Lower limits prevent carbide precipitation during welding. 3.
