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 It was later withdrawn and replaced by ASTM G31 , which currently governs the standard practice for laboratory immersion corrosion testing of metals.
Products associated with this designation must meet strict chemical requirements to ensure performance in harsh environments. Typical Range (Austenitic Grades) 16.0% – 20.0% (provides corrosion resistance) Nickel (Ni) 8.0% – 14.0% (improves toughness and ductility) Molybdenum (Mo) 2.0% – 3.0% (added in Grade 316 for pitting resistance) Carbon (C) 0.03% – 0.08% max (lower in "L" grades for weldability) Mechanical Benchmarks (Annealed State): Tensile Strength : Often exceeds 75-90 ksi. Yield Strength : Typically starts at 30-45 ksi. : Generally measured via Brinell or Rockwell scales (e
In modern industrial contexts, materials labeled under this designation are typically austenitic stainless steels known for their exceptional corrosion resistance and mechanical durability.
