304 Stainless Steel Seamless Pipe

Manufactured by JILAIDA, our 304 Stainless Steel Seamless Pipe is produced via the hot-rolled seamless route, yielding a uniform, defect-free tubular product suitable for pressure service, structural applications, and fluid transport. Standard stock dimensions cover outer diameters from 6mm to 89mm, wall thicknesses from 3mm to 30mm, and lengths between 3000mm and 10000mm. We also accommodate bespoke size requests, end preparations, and surface treatments. As a factory-direct China supplier, we help procurement teams cut out intermediaries and secure better landed costs on 304 Stainless Steel Seamless Pipe.

Key Features

1 Versatile General Corrosion Resistance

With 18% chromium and 8% nickel, 304 stainless steel develops a passive chromium oxide film that resists oxidation, mild acids, and atmospheric corrosion across a broad range of service environments. It handles freshwater, steam, food-grade media, architectural exposure, and most organic chemicals without degradation — making it the default material for general-purpose piping where neither extreme temperature nor aggressive chemical attack is present.

2 Excellent Fabrication and Welding Characteristics

304 stainless steel bends, flares, and welds readily using all standard techniques including TIG, MIG, and resistance welding. Its low carbon content (≤0.08%) in the standard grade minimizes sensitization risk during welding of thinner sections. For heavier-wall fabrication, Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. also supplies the 304L variant with extra-low carbon for maximum weld-zone corrosion resistance.

3 Hot-Rolled Seamless Construction for Pressure Integrity

Unlike welded alternatives, Ji lai da's 304 Stainless Steel Seamless Pipe is pierced and rolled from a solid billet — there is no longitudinal fusion line, no heat-affected zone, and no risk of weld undercut or incomplete penetration. The result is a pipe with uniform wall strength around its entire circumference, rated for higher working pressures and safer long-term operation in critical fluid and gas systems.

4 Wide Service Temperature Range

304 performs reliably from cryogenic temperatures down to -196°C through to intermittent service around 870°C. It retains good toughness at sub-zero conditions and resists scaling in moderately elevated-temperature air. While not a dedicated high-temperature alloy like 310 or 310S, it covers the vast majority of ambient to medium-heat industrial applications at a significantly lower material cost.

5 Competitive Supply from a Vertically Integrated China Mill

Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. operates its own hot-rolling, pickling, straightening, and testing lines — meaning we control quality and cost at every step. For overseas buyers, this translates to shorter lead times, transparent mill pricing, and the ability to handle mixed-container shipments combining 304 with other grades from our portfolio. We support FOB, CIF, and DDP delivery terms to major ports worldwide.

• Marine hardware and coastal architectural fixtures

Frequently Asked Questions

Q1: Why source 304 Stainless Steel Seamless Pipe from Jiangsu Ji Lai Da?

A: Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. is a factory-direct China manufacturer, not a trading intermediary. We provide mill-original material with full traceability, competitive FOB pricing, flexible MOQs, and a dedicated export documentation team. Buyers can consolidate 304 with our nickel-based alloy or specialty stainless products in a single container for logistical efficiency.

Q2: What is the difference between 304 and 304L stainless steel?

A: The primary distinction lies in carbon content — 304L contains ≤0.03% carbon versus ≤0.08% for standard 304. This extra-low carbon level further suppresses chromium carbide precipitation during welding, making 304L the preferred choice for heavy-gauge welded fabrications. Jiangsu Ji Lai Da can supply either grade, and our team is happy to advise based on your specific fabrication plan.

Q3: What stock sizes are available for prompt shipment?

A: Our warehouse maintains regular inventory of 304 Stainless Steel Seamless Pipe in outer diameters from 6mm to 89mm, wall thicknesses from 3mm to 30mm, and lengths from 3000mm to 10000mm. Commonly requested dimensions can ship within days; custom-cut and non-standard sizes are produced to order with lead times typically ranging from 10 to 25 days.

Q4: Can 304 seamless pipe be used outdoors or in coastal environments?

A: Yes — 304 performs well in rural and urban atmospheric exposure and moderate coastal conditions. However, in environments with heavy salt spray, direct seawater immersion, or de-icing salt exposure, 316/316L stainless steel may offer better pitting resistance. For guidance on material selection, reach out to the engineering support desk at Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd.

Q5: What inspection and certification does Ji lai da provide?

A: Every shipment of 304 Stainless Steel Seamless Pipe includes an EN 10204 3.1 Material Test Certificate documenting chemical analysis, tensile properties, flattening/flaring test results, and hydrostatic or eddy current examination. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. also accommodates third-party inspection by SGS, TÜV, Lloyd's Register, or Bureau Veritas as specified in the purchase contract.
