304 stainless steel coil mainly consists of:
304 stainless steel coil comes in several common surface finishes tailored to different needs:
| Finish Type | Description | Use & Benefits |
|---|---|---|
| 2B Finish | Smooth, matte, cold-rolled | Good for general use, easy to clean |
| BA (Bright Annealed) | Highly reflective, glossy | Decorative, food-grade applications |
| No.4 Brushed | Satin finish with fine lines | Stylish look, hides fingerprints |
| HL (Hairline) | Linear brushed texture | Modern aesthetic, high-end decor |
| 8K Mirror | Mirror-like, ultra-smooth | Premium finish, high reflectivity |
| No.1 Hot Rolled | Rough, dull finish | Industrial use, less demand on appearance |
These finishes affect not only the aesthetic appeal but also cleansability and corrosion resistance. For example, bright and mirror finishes are easier to clean and preferred in food processing, while brushed finishes help mask minor scratches.

Choosing the right surface finish and processing ensures your 304 stainless steel coil delivers the best performance, appearance, and longevity in your application.
304 stainless steel coil is widely used across many industries due to its excellent corrosion resistance and versatility. It’s a top choice for food processing and kitchen equipment, where hygiene and durability are paramount. In the chemical and pharmaceutical sectors, 304 coil is ideal for equipment and piping that require corrosion resistance and easy cleaning.
Architectural uses include decorative panels, facades, and railings, where 304 stainless steel’s attractive finish and weather resistance stand out. In the automotive industry, it serves in trim, exhaust components, and structural parts thanks to its strength and heat resistance.
304 coil is also essential for heat exchangers and HVAC systems, performing reliably under fluctuating temperatures. The medical field favors it for medical, dairy, and beverage handling equipment due to its sanitary properties. Finally, it suits general fabrication tasks, storage tanks, and even cryogenic applications, proving its adaptability across temperature extremes.

At Xinye Steel, the production of 304 stainless steel coil starts with advanced hot rolling to shape the coil, followed by cold rolling to achieve precise thickness and smooth surface quality. We then use controlled annealing to enhance ductility and relieve internal stresses, ensuring superior performance. Final finishing processes include leveling and protective film application for flawless coil surfaces.
Quality is key. Each batch undergoes strict chemical analysis and mechanical testing to meet standards like ASTM A240 and EN 10088-2. Our surface inspections and non-destructive testing guarantee no defects or inconsistencies, giving you reliable, high-grade SUS 304 coil every time. We back our products with certifications such as ISO, SGS, ROHS, and provide detailed mill test certificates to prove compliance.
Traceability is fully maintained from raw materials to finished hot or cold rolled coils, ensuring batch-to-batch consistency. This rigorous process control means you get consistent quality whether you order standard or custom dimensions, crucial for sensitive applications like food or pharmaceutical equipment.

304 has a max carbon content of 0.08%, making it strong but slightly less weldable.
304L has lower carbon (max 0.03%), reducing carbide precipitation and improving weldability for critical applications.
For projects involving welding or bending, 304L is often preferred.
2B finish is common for food processing due to its smoothness and ease of cleaning.
No.4 brushed finish is also popular for kitchen equipment with better scratch resistance.
Avoid rough finishes that can trap bacteria or debris.
304 performs reasonably in freshwater and mild atmospheres.
However, it’s not the best choice for chloride-heavy environments like seawater, where 316 or 316L coils perform better due to higher corrosion resistance.
Use this simple formula:
| Parameter | Description |
|---|---|
| Thickness (T) | mm |
| Width (W) | mm |
| Length (L) | mm |
| Density of 304 SS | 8.0 g/cm³ (or 8000 kg/m³) |
Weight (kg) = T × W × L × Density / 1,000,000
Example: A coil 1.0 mm thick, 1000 mm wide, and 2000 mm long:
Weight = 1 × 1000 × 2000 × 8 / 1,000,000 = 16 kg
