06Cr17Ni12Mo2 Stainless Steel Extruded Seamless Pipe

The Molybdenum That Makes the Difference

Add 2–3% molybdenum to an 18-8 stainless and you get a grade that doesn't just survive in chlorides — it holds up. That's the leap from 304 to 316, or in Chinese nomenclature, from 06Cr19Ni10 to 06Cr17Ni12Mo2. The molybdenum slows pitting initiation in salt water, acidic condensate, and chloride-laden process streams. It doesn't make the alloy immune — no stainless is — but it pushes the failure horizon far enough that 316 becomes the practical choice for desalination, offshore, and coastal infrastructure across the Gulf and South Asia. The 06Cr17Ni12Mo2 stainless steel extruded seamless pipe from Jilaida factory is produced by hot extrusion: single-stroke forming, no longitudinal seam, uniform grain structure from outside wall to inside wall.

How Your Market Names This Alloy

Seamless by Design, Not by Chance

In Gulf desalination plants and Indian coastal refineries, the 06Cr17Ni12Mo2 stainless steel extruded seamless pipe is often specified not because welded 316 pipe can't hold the pressure — it can, at a lower joint efficiency — but because the inspection regime demands it. Seamless pipe eliminates the long seam, which means no radiographic examination of a longitudinal weld, no weld defect rejection during installation, and no seam corrosion under insulation in humid saline air. The hot extrusion process at Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. forms each pipe in a single press stroke at temperatures above 1100 °C, producing a hollow with continuous grain flow and wall thickness controlled within ±0.3 mm. Yield rate exceeds 95%, material waste stays below 5%.

Where This Pipe Actually Works

MED and MSF desalination plant brine and product water piping — this is the single largest application for 316-class seamless pipe in the Gulf. Offshore platform utility lines where salt spray is constant. Petrochemical process lines handling sour water and amine solutions. Pharmaceutical water systems (PW, WFI) that mandate seamless per ASME BPE. Seawater-cooled heat exchanger tubes where 304 would pit within months. Coastal HVAC condensate return piping in towers from Dubai to Mumbai to Ho Chi Minh City.

In India, the 06Cr17Ni12Mo2 stainless steel extruded seamless pipe also serves as feedstock for the local cold-drawing industry — smaller workshops buy semi-finished hollows and draw them down to thin-wall precision tubes for instrumentation and hydraulic use. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. supports this channel with consistent extrusion quality: uniform starting dimensions mean reliable drawing yields downstream.

How to Order

Specify the grade by the standard your project uses — GB/T 14976 06Cr17Ni12Mo2 for China-origin specs, ASTM A312 TP316 for Gulf and Southeast Asian projects, IS 6911 for Indian installations. We match the designation and certify accordingly on the EN 10204 3.1 MTC. Factory-direct from China, FOB / CIF / DDP delivery to Jebel Ali, Mumbai, Singapore, Laem Chabang, or any port you nominate. ISO 9001 + 4 additional certifications on the production line. RFQ with grade, OD, wall, length, and quantity — pricing and lead time returned within one business day.

FAQ

Q1: Is 06Cr17Ni12Mo2 the same as 316L?

A: Not quite. 06Cr17Ni12Mo2 is the standard-carbon 316 (C ≤ 0.08%). 316L is the low-carbon variant (C ≤ 0.035%), designated 022Cr17Ni12Mo2 under GB/T. If you're welding the pipe into a system without post-weld annealing, specify the L-grade. For non-welded or annealed-after-weld service, standard 316 is fine and slightly stronger.

Q2: Can 316 handle Arabian Gulf seawater?

A: For limited exposure — splash zones, intermittent flow, low-temperature service — yes. For continuous immersion in warm Gulf seawater, 316 will eventually pit. Duplex 2205 or super-duplex 2507 is the safer choice for full-immersion seawater service. Many Gulf desalination plants use 316 for product water and low-chloride streams, and duplex for the high-chloride loops.

Q3: What certification do Indian buyers typically require?

A: Most Indian EPC contractors accept ASTM A312 TP316 with EN 10204 3.1 MTC. Some government-linked projects may ask for BIS certification or testing at an NABL-accredited lab. We can arrange third-party inspection through agencies recognized in India — specify the requirement at order stage.

Q4: Do you supply to Gulf projects with SASO or QGOS certification?

A: Saudi and Qatari projects generally accept ASTM A312 with mill test certificates. SASO compliance for steel products is a customs requirement we can support with the proper documentation. For project-specific inspection regimes (e.g., Sabic, Adnoc, QatarEnergy vendor lists), we work with your third-party inspection agency to meet their pre-qualification.

Q5: Semi-finished hollows for cold drawing — what's the advantage?

A: Our OD 89 × WT 9 mm extruded hollow is produced specifically as parent stock. Consistent OD and wall thickness mean your cold pilgering or drawing setup runs without frequent adjustment, reducing tool wear and scrap. The seamless origin also means no hidden weld defects that would only show up after drawing.

Q6: What's the typical lead time to Jebel Ali or Mumbai?

A: Production 2–4 weeks for standard sizes, plus 2–3 weeks sea freight to Jebel Ali or Nhava Sheva. Total 5–7 weeks door to port is typical. Stock sizes can sometimes ship faster — check availability with your RFQ.
