ASTM A815 - Pipe or Buttweld Fittings

ASTM A815 Pipe Fittings

ASTM A815 specification stands for stainless steel pipe fittings or buttweld fittings. Seamless Pipe Fittings forms are tees, elbows, reducers, end caps in 1/8” NBt to 24" NB. Also cross, swage nipple, return bends pipe fitting form in size 1/8” NB to 8" NB are produced by Siddhagiri Metals and Tubes.

Scope And Manufacturing

ASTM A815 specification covers stainless steel pipe fitting (UNS S31803, UNS S32760, UNS S32205, UNS S32750) components used in pharmaceuticals, heat exchangers. The stainless steel is melted in electric furnace, vacuum furnace followed by vacuum or electroslag-consumable remelting. Forging or shaping operations are performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by combination of two or more of these operations. The materials undergo heat treatment and follow the required cooling process and tempering temperature. Chemical and product analyses is performed and is conform to the required chemical composition in carbon, manganese, phosphorus, silicon, sulfur, nickel, chromium, molybdenum, copper, nitrogen. The mechanical properties of the pipe fitting material is tested for yield strength, tensile strength, elongation, and hardness.

Siddhagiri Metals and Tubes offers Duplex 2205, Super Duplex S32750, Super Duplex S32760 grades which have very good resistance to uniform corrosion. We are the exporter and manufacturer of these pipe fittings which are high quality and provides high mechanical strength, good weldability and good corrosion resistance.


ASTM A815 specification stands for super duplex stainless steel pipe fittings and buttweld fittings. It is used in umbilicals, storage tanks and pressure vessels.
