GB/T 4237 06Cr19Ni10N（304N) Stainless Steel Plate Supplier

06Cr19Ni10N Stainless Steel Coil & Plate | GB/T 4237 06Cr19Ni10N（304N) Stainless Steel Sheet Manufacturer & Exporter – Gangsteel

Gangsteel is a leading manufacturer and global exporter of GB/T 4237 06Cr19Ni10N stainless steel hot-rolled coils, plates, and wide heavy plates. Known internationally as Grade 304N (nitrogen-enhanced variant of 304), 06Cr19Ni10N is an austenitic chromium-nickel stainless steel with controlled nitrogen addition (0.10–0.16%) that significantly improves yield strength, tensile strength, and pitting corrosion resistance while retaining the excellent formability, weldability, and general corrosion resistance of standard 304.

With 18% Cr, 8–11% Ni, and intentional nitrogen strengthening, 304N offers higher mechanical performance than conventional 304 (06Cr19Ni10) — especially in annealed condition — making it ideal for structural applications, pressure vessels, heat exchangers, and components requiring improved strength without sacrificing corrosion resistance or fabricability.

Produced under GB/T 4237-2015 (Stainless Steel Hot-Rolled Sheets and Strips), Gangsteel supplies 06Cr19Ni10N in thicknesses from 2 mm to 500 mm and widths up to 4200 mm — one of the widest hot-rolling capabilities in the industry. Our products are delivered in standard hot-rolled finishes No.1 (annealed & pickled) and 2D (annealed & pickled dull) and are exported worldwide to chemical processing, energy, food & beverage, architectural, rail transit, and heavy fabrication sectors.

Manufacturing Process: Hot Rolled at Gangsteel

Gangsteel's hot-rolling process for 06Cr19Ni10N includes:

1. Electric arc furnace + AOD refining → precise nitrogen control
2. Continuous casting into wide slabs
3. Reheating to 1150–1250°C
4. Hot rolling on wide heavy-plate mills (up to 4200 mm width)
5. Controlled cooling, leveling, and descaling
6. Solution annealing + pickling for No.1 finish or shot blasting + pickling for 2D finish
7. Edge trimming, coil splitting, or cut-to-length

Thickness range: 2 mm – 500 mm Width range: up to 4200 mm Length: up to 18 m (plate) or coil form

Finishes: No.1 (annealed & pickled), 2D (annealed & pickled dull)

Available Forms, Sizes, and Specifications

• Hot-rolled coils: 2.0–25.0 mm thick, up to 4200 mm wide
• Hot-rolled plates: 2.0–500 mm thick, up to 4200 mm wide × 18 m long
• Cut-to-size plates, slit coils, custom blanks

All compliant with GB/T 4237-2015; optional third-party certification (SGS, TUV, BV).

Key Applications of 06Cr19Ni10N (304N) Hot-Rolled Products

• Pressure vessels and storage tanks requiring higher strength
• Heat exchangers and chemical processing equipment
• Food and pharmaceutical hygienic vessels
• Architectural structural components and rail transit parts
• High-strength welded pipes and fittings
• Cryogenic and low-temperature applications

Advantages of Choosing 06Cr19Ni10N (304N)

• 20–30% higher yield strength than standard 304
• Excellent general corrosion resistance in mild environments
• Superior weldability and formability
• Good strength and toughness from cryogenic to elevated temperatures
• Non-magnetic annealed; easy to clean and polish
• Cost-effective upgraded performance vs. 304
• Wide global acceptance and recyclability

Corrosion and Oxidation Resistance

Forms stable Cr oxide layer; resists rust in fresh water, mild acids, organics, and atmospheres. Nitrogen addition slightly improves pitting resistance. Oxidation resistance up to ~870°C intermittent.

Weldability and Fabrication

Excellent weldability with TIG/MIG/resistance/laser; low carbon minimizes sensitization. Use ER308/ER308L fillers. High ductility supports complex forming.

FAQ

Q1: What is the main benefit of 304N (06Cr19Ni10N) over standard 304?

A: The intentional nitrogen addition increases yield strength by 20–30% while maintaining similar corrosion resistance and formability, making it ideal for structural and pressure-containing applications.

Q2: Can 06Cr19Ni10N be used in coastal or chloride-containing environments?

A: Suitable for mild exposure, but for long-term marine or high-chloride service, 316L or 444 is recommended for superior pitting resistance.

Q3: What finishes are available under GB/T 4237 for hot-rolled 304N?

A: Standard finishes are No.1 (annealed & pickled) and 2D (annealed & pickled dull). No.1 is most common for further processing.

Q4: What is the maximum width and thickness Gangsteel can produce for 06Cr19Ni10N?

A: Up to 4200 mm wide and 500 mm thick in hot-rolled plates; coils typically 2–25 mm thick.

Q5: Is 304N weldable? What filler should be used?

A: Yes, excellent weldability. Use ER308 or ER308L fillers for matching properties.

Q6: Does Gangsteel offer third-party inspection for GB/T 4237 304N material?

A: Yes — SGS, TUV, BV, or customer-nominated agencies are welcome at any stage.

Q7: What is the lead time for hot-rolled 06Cr19Ni10N coils or plates?

A: Standard sizes from stock: 7–15 days. Custom wide/heavy plates: 25–45 days depending on thickness and quantity.

Q8: Can Gangsteel provide 304N with BA or 2B finish?

A: Hot-rolled material is No.1 or 2D. For BA or 2B, we supply cold-rolled versions under GB/T 3280.
