GB/T 4237 06Cr19Ni10（304) Stainless Steel Plate Supplier

06Cr19Ni10 Stainless Steel Coil & Plate | GB/T 4237 06Cr19Ni10（304) Stainless Steel Sheet Manufacturer & Exporter – Gangsteel

Gangsteel is a leading manufacturer and global exporter of GB/T 4237 06Cr19Ni10 stainless steel hot-rolled coils, plates, and wide heavy plates. Known worldwide as Grade 304 — the most versatile and widely used austenitic stainless steel — 06Cr19Ni10 delivers outstanding general corrosion resistance, excellent formability, superior weldability, and proven performance across food processing, chemical equipment, architectural, pharmaceutical, and pressure vessel applications.

With the classic 18/8 composition (18% Cr, 8–10.5% Ni), it forms a stable passive chromium oxide layer that self-heals in oxidizing conditions, providing reliable protection in atmospheric, fresh water, mild acid/organic, and food environments. Gangsteel supplies 06Cr19Ni10 under GB/T 4237-2015 (Stainless Steel Hot-Rolled Sheets and Strips) in thicknesses from 2 mm to 500 mm and widths up to 4200 mm — among the widest hot-rolling capabilities available globally. Our products are offered in standard hot-rolled finishes No.1 (annealed & pickled) and 2D (annealed & pickled dull) and are exported to over 60 countries for demanding industrial and commercial projects.

Manufacturing Process: Hot Rolled at Gangsteel

Gangsteel's hot-rolling process for 06Cr19Ni10 includes:

1. Electric arc furnace + AOD refining → precise chemistry 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

FAQ

Q1: What is the main difference between 304 (06Cr19Ni10) and 304L (022Cr19Ni10)?

A: 304 has carbon ≤0.08%, while 304L has ≤0.030%. 304L offers better weld-zone corrosion resistance and is preferred for welded structures; 304 is used when higher strength is needed and welding is minimal.

Q2: Can 06Cr19Ni10 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 304?

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 06Cr19Ni10?

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

Q5: Is 304 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 304 material?

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

Q7: What is the lead time for hot-rolled 06Cr19Ni10 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 304 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.
