316L Stainless Steel Coil
316L stainless steel is a variant of 316 stainless steel with a lower carbon content and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone close to the weld, and the precipitation of carbides may cause intergranular corrosion of stainless steel in certain environments. Basically, using 316L eliminates the need to anneal weld joints prior to using the completed metal form, saving time and effort. 316L stainless steel is the second most widely used stainless steel after 304, and its corrosion resistance is better than 304. High temperature resistance is also better, up to 1000 degrees. 316L stainless steel is a kind of universal stainless steel material, rust resistance is stronger than 200 series stainless steel material. 316L stainless steel is widely used in the chemical industry because of its excellent corrosion resistance.
Each coil undergoes refined hot-rolling or cold-rolling processes based on application needs. Hot-rolled coils deliver superior strength and are suitable for heavy-duty structural components, while cold-rolled coils offer a smoother surface finish and tighter dimensional control—perfect for products requiring aesthetic appeal, such as decorative panels or electronic enclosures.
Surface treatments are tailored to enhance both functionality and appearance:
2B Finish: A smooth, matte surface ideal for general fabrication and painting.
BA Finish: A bright, reflective surface often used in appliances and visible architectural elements.
No.4 Finish: A brushed surface that reduces fingerprint visibility, making it popular for kitchen countertops and medical equipment.
Our stainless steel coils are manufactured through advanced hot and cold rolling processes to meet diverse industrial requirements. The hot rolling process utilizes controlled heating and multi-pass rolling technology to form coils with uniform microstructure and excellent mechanical properties, providing an ideal solution for applications requiring higher thickness tolerance and structural strength. This is complemented by our fully automated cold rolling mills and protective atmosphere annealing processes, equipped with laser thickness gauges (thickness tolerance ±0.01mm) and online surface defect detection systems to ensure dimensional precision and surface quality meeting 2B/BA/No.4 standards.
The integrated production line includes 20-roll reversible rolling mills, hydrogen bright annealing lines (temperature accuracy ±3°C), and fully automatic coiling equipment. Compliant with international standards such as ASTM A240 and EN 10088, we support customization of various specifications, special materials, and differentiated surface treatments. Our products are widely used in new energy vehicles, home appliance manufacturing, precision electronics industries, and other fields requiring both structural components and precision materials.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
