Advanced Slitting & Surface Protection
Precision Slitting: We utilize high-speed precision slitting lines to provide narrow 304L strips for stamping and tube-making, ensuring minimal edge burrs.
Surface Consistency: Our BA (Bright Annealed) and 2B finishes are processed in a controlled atmosphere to ensure consistent color and reflectivity across the entire coil length.
Pro-Grade Packaging: To prevent scratches and oxidation, every coil is interleaved with paper or protected by Laser-grade PE/PVC film, then secured on export-standard wooden or metal pallets.
Why Choose 304L Cold Rolled? For applications requiring extensive deep drawing or welding in thin-wall components, our 304L coils offer better grain structure and resistance to intergranular corrosion.
304 304L Cold Rolled Stainless Steel Coil Data Sheet
304 stainless steel is a versatile stainless steel with rust-proof performance compared to the 200 series of stainless steel. The high temperature is also better, and can be as high as 1000-1200 degrees. 304 stainless steel exhibits excellent corrosion resistance and superior resistance to intergranular corrosion. Of the oxidizing acid, the experiment concluded that a concentration ≤P 65% of nitric acid below the boiling temperature, 304 stainless steel has strong corrosion resistance.

304 vs 304l Stainless Steel Coil
304 stainless steel (UNS S30400 / EN 1.4301) is a widely used austenitic alloy with a balanced combination of corrosion resistance, strength, and formability. Its lower carbon version, 4304L (UNS S30403 / EN 1.307), is preferred for applications requiring extensive welding or minimized risk of intergranular corrosion.
Cold rolled stainless steel coils are produced by cold reducing annealed stainless strip to achieve a smooth, uniform surface and tighter dimensional tolerances compared to hot rolled products.
Both 304 and 304L cold rolled coils are suitable for precision fabrication, deep drawing, stamping, and high‑finish surface applications.
304 stainless steel contains between 0.08% and 0.10% carbon, while 304L stainless steel contains less than 0.03% carbon. This lower carbon content in 304L makes it more resistant to sensitization, a type of corrosion that can occur when stainless steel is heated to high temperatures.
Because of its lower carbon content, 304L is often used in welding applications where high temperatures are involved, such as in the manufacturing of piping and tubing. It is also often used in applications where corrosion resistance is important, such as in the food and beverage industry.
In terms of their physical properties, 304 and 304L are very similar. Both have excellent corrosion resistance, good weldability, and high strength and hardness. They are both non-magnetic and have a high oxidation resistance.
Overall, the choice between 304 and 304L will depend on the specific application and the conditions under which the stainless steel will be used. If high temperatures are involved, or if corrosion resistance is a top priority, then 304L may be the better choice.
FAQ: Professional Sourcing of 304L/304 Cold Rolled Coils
What is the difference between 2B and BA finish for 304 coils?
2B finish is a smooth, non-reflective matte finish, most commonly used in industrial and kitchen equipment. BA (Bright Annealed) is processed by heat treatment in a controlled atmosphere furnace, resulting in a mirror-like, highly reflective surface ideal for decorative trim and appliances.
Can you provide 304L coils for deep-drawing (DDQ) quality?
Yes. For manufacturers of sinks, pots, or complex automotive parts, we offer 304/304L DQ DDQ (Deep Drawing Quality) coils with optimized elongation and mechanical properties to prevent cracking during the drawing process.
What is the minimum order quantity (MOQ) for custom-width slitting?
For standard stock items, the MOQ is as low as 1-3 tons. For custom precision slitting of ultra-narrow strips, please contact us with your specific requirements for a tailored lead time.
Do you provide MTC with every 304L coil shipment?
Absolutely. We provide a full Mill Test Certificate (MTC) per EN 10204 3.1, detailing the chemical analysis, tensile strength, yield strength, and elongation to ensure 100% material compliance.
What is the difference between 304 and 304L cold rolled coils?
304L has lower carbon content, offering better weldability and reduced intergranular corrosion risk, especially in welded assemblies.
Do you accept custom thickness and width?
Yes, we support custom coil specifications based on your project requirements.
