08Х18Н10 Hot Extruded Pipe

What Hot Extrusion Gives This Grade

08Х18Н10 is a soft, ductile austenitic alloy — easy to form, easy to weld, but also easy to work-harden if you try to cold-process it too aggressively. Hot extrusion sidesteps that problem entirely. The billet is heated above 1100 °C, where the alloy flows plastically under the extrusion press, and the pipe takes shape in seconds. The result is a seamless hollow with uniform wall, continuous grain flow, and no residual cold-work stress. For the 08Х18Н10 hot extruded pipe offered by JILAIDA, a professional manufacturer in China , this means consistent hardness from OD to ID, no seam to inspect or reject, and a hydrostatic test performance that meets ASME B31.3 seamless joint efficiency of 1.0 without additional qualification.

Real-World Uses

In CIS countries, 08Х18Н10 is the default stainless grade — it appears in GOST-designed chemical plants, power station piping, food facility process lines, and residential heating systems across Russia, Kazakhstan, Uzbekistan, and Belarus. But the same pipe, under its ASTM or EN name, ships to projects in the Middle East, Southeast Asia, and Africa. The 08Х18Н10 hot extruded pipe doesn't change its chemistry at the border — only the paperwork does. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. understands this, which is why we certify to whichever standard your project requires, using the designation your inspector expects to see.

Typical service points: low-chloride process water transport. Dairy and brewery CIP loops where crevice-free seamless construction is mandatory. Steam condensate return lines. Instrument air headers in corrosive atmospheres. Light-duty chemical transfer where 316 is over-specified and carbon steel won't last a season. And increasingly, as a parent tube for cold-rolling to thin-wall precision tubing used in automotive and hydraulic applications.

Ordering and Documentation

Every lot of 08Х18Н10 hot extruded pipe ships with an MTC per EN 10204 3.1 — full chemical analysis, tensile and yield data, elongation, and hardness. If your purchase order cites GOST 9940 or GOST 11068, we'll align the certificate accordingly. If it cites ASTM A312 TP304, same thing. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. operates under ISO 9001 plus four additional certifications, and ships factory-direct from China on FOB, CIF, or DDP terms. RFQ by grade designation, OD, wall thickness, length, and quantity — we respond with pricing and delivery within one business day.

FAQ

Q1: Is 08Х18Н10 exactly the same as 304 in composition?

A: Close but not identical at the tolerance limits. GOST 5632 allows slightly wider ranges on chromium and nickel compared to ASTM A240. In practice, reputable mills target mid-range chemistry that satisfies both standards simultaneously. We verify this on every heat and can supply the full analysis for your comparison.

Q2: What about 12Х18Н10Т — is that also 304?

A: No. 12Х18Н10Т is a titanium-stabilized grade — closer to 321 than 304. The 'Т' stands for titanium, which prevents carbide precipitation during welding. It's common in older GOST-designed plants. If your spec calls for 12Х18Н10Т, you need 321 or 1.4541, not 08Х18Н10. We produce both — just make sure the designation is clear on your RFQ.

Q3: Can you certify to GOST on an MTC?

A: Yes. We issue the material certificate with the GOST designation and the corresponding GOST test method references where applicable. For CIS-bound shipments, this avoids the need for your QA team to cross-reference between EN and GOST on every line item.

Q4: What's the carbon difference between 08Х18Н10 and 04Х18Н10?

A: 08Х = ~0.08% C max (standard grade, equivalent to 304). 04Х = ~0.04% C max (low-carbon, equivalent to 304L). The same distinction as 304 vs 304L. If welding is involved and post-weld annealing is impractical, specify 04Х18Н10 / 304L.

Q5: Do you supply semi-finished hollows for further cold rolling?

A: Yes. Our OD 89 × WT 9 mm extruded hollow is specifically produced as a parent tube for cold pilgering or cold drawing down to smaller ODs and thinner walls. Length 3000–3500 mm standard, extendable on request.

Q6: Packaging for CIS rail or sea shipment?

A: Bundled in steel straps with wooden dunnage, ends capped or plugged, wrapped in anti-corrosion VCI paper. For rail shipment to Central Asia we use reinforced bundles per the forwarder's handling spec. Tell us the routing and we'll match the packing.
