When someone is searching for ASTM A333 Grade 6 Pipe, the real question is almost always the same: which supplier already has the right size and schedule ready to ship. At Aesteiron Steels LLP, SA 333 Gr 6 Pipe is held in stock across the entire NPS range, meaning a confirmed order can move directly to dispatch instead of waiting on a new production run.
This material is also known under several interchangeable names – Carbon Steel A333 Gr.6 Pipe, LTCS A333 Gr 6, or ASME SA-333 Grade 6 – and is a fine-grain, fully-killed carbon steel commonly specified wherever piping must remain reliable down to −50°F (−46°C) without upgrading to a costlier nickel-alloy material. It is widely used in cryogenic transfer systems, LNG facilities, gas transmission networks, and refinery piping operating in cold climates.
Shipments dispatched from our stockyard in Mumbai to buyers across the Middle East, Africa, and the Americas are backed by dual ASTM/ASME certification, Charpy V-notch impact test reports, and an EN 10204 mill test certificate – giving EPC contractors and MRO procurement teams ready-to-use documentation without the delay of a freshly cast heat.
A quick summary of ASTM A333 Grade 6 Pipe specs – standard, size, length, and finish.
A trusted source for impact-tested pipe built for cold-climate and cryogenic-adjacent duty.
