ASTM A815 Fittings are high-performance wrought fittings designed for corrosive and high-temperature piping systems. This specification covers wrought ferritic, ferritic/austenitic (duplex), and austenitic stainless steel pipe fittings, including buttwelding and socket-welding types. Our ASTM A815 Stainless Steel Pipe Fittings are manufactured to exacting standards, ensuring superior corrosion resistance, mechanical properties, and reliability in demanding applications across chemical processing, oil and gas, power generation, and water treatment industries.
Key performance highlights
Corrosion Resistance
Austenitic structure (chromium-nickel alloying) forms a passive oxide layer that resists oxidation, mild acids, and atmospheric corrosion. Grades like 316L/317L excel in chloride-rich or chemical environments.
Weldability
All ASTM A815 Stainless Steel Pipe Fittings are weldable via TIG, MIG, or stick welding, with minimal post-weld heat treatment required (especially for low-carbon grades like 304L).
Ductility
High elongation values allow for slight deformation during installation (e.g., alignment adjustments) without cracking.
