Manufactured in strict accordance with ASTM A312 / ASME SA312 TP316 specifications, Stainless Steel 316 Pipe is an austenitic chromium-nickel alloy reinforced with molybdenum, and is recognized globally under equivalent standards such as UNS S31600, WNR 1.4401/1.4436, JIS SUS 316, and Werkstoff 1.4401. At Aesteiron Steels LLP, SS 316 pipe is maintained in continuous stock across seamless, ERW, and EFW variants, available in round, square, rectangular, and hollow section profiles — with cutting, beveling, and dispatch handled within 48 hours of confirmed orders.
What sets SS 316 pipe apart is its 2–3% molybdenum content, which significantly strengthens its defense against pitting and crevice corrosion caused by chlorides, outperforming conventional 18-8 stainless grades by a wide margin. This makes it the preferred choice for demanding applications such as offshore and marine structures, desalination facilities, effluent treatment plants, and chemical process piping exposed to saline or corrosive conditions. Complete batch traceability is standard, with every shipment backed by EN 10204 3.1/3.2 mill certification, and PED 2014/68/EU compliance provided when required.
As a leading Stainless Steel 316 Pipe Exporter we ship pipes as per ASTM A312 specification.
