316 / SUS316 / 06Cr17Ni12Mo2

316 Stainless Steel Industrial Pipe

316 stainless steel tube contains molybdenum and is selected for chloride exposure, coastal projects, chemical service and higher-corrosion environments.

Typical Applications

Chemical processing, pharmaceuticals, coastal or salt-spray environments, water treatment, high-grade food piping, heat exchangers, marine service and chloride media.

Specification Range

Outside DiameterCommon procurement range: Φ6mm-325mm; standard sizes, non-standard OD or drawing-based supply available.
Wall ThicknessCommon range: 0.3mm-10mm; chemical, pressure and heat-exchanger applications may require Schedule wall thickness.
LengthStandard 6m length; cut-to-length, random length, long length or project-specific transport length available.
FinishBA, 2B, brushed, polished, pickled and passivated, mirror finish. Corrosion-service projects often require passivation or fine polishing.
ProcessWelded or seamless; cold drawn, cold rolled, hot rolled, solution annealed, pickled, passivated or internally polished.
StandardsASTM A312, A269, A270, A778; JIS G3459; GB/T 12771; GB/T 14976.

RFQ Notes

Please confirm 316 or 316L, molybdenum requirement, intergranular corrosion requirement, passivation, roughness, pressure testing and third-party mill test certificate. OD, wall thickness and ovality requirements should be written into the order.

Procurement Guidance

316 stainless steel tube is normally chosen when the project faces chloride, salt spray, coastal air, stronger cleaning chemicals or more demanding water treatment conditions. The molybdenum content gives 316 better resistance to pitting and crevice corrosion than 304, but the final choice still depends on concentration, temperature, cleaning method and service life expectations.

For chemical, marine or food-related projects, list the exact medium and any roughness or passivation requirements. If a buyer needs 316L, third-party inspection, EN 10204 3.1 certificate or PMI testing, those requirements should be stated before quotation because they affect availability, lead time and packing documentation.
