  • Excellent Corrosion Resistance

    Outstanding corrosion resistance in atmospheric, fresh water and weak acid-alkali environments, with salt spray resistance test showing no rust spots for ≥500 hours.

  • Superior Formability

    Good cold working plasticity, capable of withstanding complex forming processes such as deep drawing and flanging. For example, the qualified rate of kitchenware stretched parts is ≥95%.

  • Stable Surface Quality

    The 2B surface is smooth and uniform, facilitating subsequent secondary processing such as coating and printing, and adapting to the needs of appearance parts.

Additional Information

Surface Treatment

Customizable surfaces such as BA (bright annealing), 8K mirror, and HL (brushed) are available; please specify in advance.

Packaging & Transportation

Packed with moisture-proof paper and galvanized iron sheets. Each coil weighs ≤10 tons. Wooden crates are required for fixing during sea transportation.

Inventory & Lead Time

Regular specifications (0.5-3.0mm×1219mm) are fully stocked, with delivery within 48 hours; the customization cycle for special specifications is 15-20 days.

Welding Recommendations

TIG welding is recommended, using ER308L welding wire. No preheating is required before welding; interpass temperature should be ≤150℃. Post-weld pickling and passivation are recommended.

FAQs

 Can you handle shipping and custom clearance to UAE？
Yes. We have mature logistics solutions for the Middle East and Southeast Asia, including reinforced packaging (moisture-proof/galvanized iron sheets) to prevent corrosion during sea transit. We provide all necessary shipping documentation for smooth customs clearance.
Can you provide a third-party inspection?
Absolutely. We support SGS, BV, or other third-party inspections before shipment to ensure your cargo meets all project specifications.
What is 304 cold rolled stainless steel coil?
It is a widely used austenitic stainless steel coil produced by cold rolling for improved surface finish and dimensional accuracy.
What are typical applications of 304 cold rolled coils?
Food processing equipment, kitchenware, architectural panels, and general fabrication.
How does cold rolled coil differ from hot rolled coil?
Cold rolled coils offer smoother surfaces, tighter tolerances, and better formability.
Is 304 cold rolled coil easy to form and weld?
Yes. It has excellent formability and weldability for most fabrication processes.
