As a leading manufacturer with a strong export presence, Wuxi Yansheng Technology Co., Ltd. specializes in providing high-quality, cost-effective stainless steel coils tailored to diverse industrial needs. Our extensive range, featuring thicknesses from a precise 0.3mm to a robust 3.0mm, is engineered to deliver superior performance, aesthetic appeal, and long-term durability. We understand the critical balance between quality and budget in global procurement, which is why our "Low Price" offering does not compromise on the material integrity or the precision of finishes like 2B, BA, and brilliant 8K Mirror. With a factory equipped for large-scale production and a commitment to stringent quality management systems, we are your reliable partner for premium stainless steel solutions that enhance your product value and operational efficiency.
Our stainless steel coils are manufactured to meet exacting standards, ensuring consistency and reliability for your fabrication processes. We utilize advanced rolling and finishing technologies to achieve the specified surface characteristics and dimensional tolerances.
Premium Material Selection: We offer a comprehensive selection of Austenitic stainless steel grades, including the economical 201 series and the superior corrosion-resistant 304/304L and 316/316L series. Each grade is selected and processed to provide optimal properties for its intended application, from general-purpose use to demanding environments involving chlorides or acids.
Precision Thickness & Surface Finishes: Our production capability covers a wide spectrum from ultra-thin 0.3mm coils for intricate components to thicker 3.0mm coils for structural applications. The surface finish is a critical quality parameter:
2B Finish: A smooth, moderately reflective cold-rolled finish, commonly used for industrial and general-purpose applications. It offers good corrosion resistance and is easy to clean.
BA (Bright Annealed) Finish: A highly reflective, smooth surface achieved by bright annealing in a controlled atmosphere furnace. It provides a clean, shiny appearance suitable for appliances and decorative trim.
8K Mirror Finish: This is a premium mirror-polished finish with exceptional reflectivity and clarity, achieved through a multi-step polishing process. It is the choice for high-end architectural cladding, decorative panels, and luxury item manufacturing.
Cold Rolled vs. Hot Rolled: We supply both processing types to suit different requirements. Cold-rolled coils generally have tighter dimensional tolerances, a smoother surface, and increased strength through work hardening. Hot-rolled coils are typically used where precise thickness and surface finish are less critical, often for further processing or structural parts.
Technical Advantages & Customer Benefits:
Consistent Quality: Our integrated manufacturing process and quality control ensure uniform mechanical properties, chemical composition, and surface quality across every coil.
Enhanced Formability: The coils are supplied in an annealed condition, providing excellent ductility for bending, stamping, and deep drawing operations without cracking.
Corrosion Resistance: Particularly for 304/L and 316/L grades, the high chromium and nickel (and molybdenum in 316/L) content offers outstanding resistance to a wide range of corrosive environments, extending product lifespan.
Aesthetic Versatility: From the functional 2B to the luxurious 8K mirror, our finishes allow designers and engineers to meet both functional and visual design criteria.
Supply Chain Efficiency: With a large annual export volume and major port access, we ensure reliable, timely shipments and can handle both large bulk orders and customized smaller lots.
Below is a reference table outlining key specifications for our standard stainless steel coil offerings:
| Grade | Typical Composition (Key Elements) | Primary Characteristics | Common Applications |
|---|---|---|---|
| 201 | Cr, Ni-Mn alloy | Cost-effective, good strength and formability | Indoor decoration, kitchen utensils, tubing |
| 304 / 304L | 18% Cr, 8% Ni (Low C in 304L) | Excellent corrosion resistance, weldability | Food processing, chemical equipment, architectural |
| 316 / 316L | 16-18% Cr, 10-14% Ni, 2-3% Mo | Superior corrosion resistance, especially to chlorides | Marine environments, pharmaceutical, coastal architecture |

Frequently Asked Questions (FAQ)
Q1: What is the main difference between 304 and 316 stainless steel coils?
A: The primary difference is the addition of Molybdenum (Mo) in 316-grade steel (approximately 2-3%). This element significantly enhances corrosion resistance, particularly against chlorides and industrial solvents, making 316 more suitable for harsh environments like marine or chemical processing applications. 304 is an excellent general-purpose grade for most environments.
Q2: Can you supply coils with a non-standard width or thickness?
A: Yes, customization is a key part of our service. While we stock standard sizes, our production lines can be adjusted to produce coils in specific widths and within the advertised thickness range (0.3mm-3.0mm) according to your technical drawings or specifications. Please inquire with your detailed requirements for a feasibility check and quote.
Q3: How is the 8K mirror finish achieved, and how do I maintain it?
A: The 8K mirror finish is produced through a multi-stage mechanical polishing process using progressively finer abrasives, followed by buffing to achieve a high-gloss, reflective surface. To maintain it, clean with a soft cloth, mild soap, and water. Avoid abrasive cleaners or pads, as they can scratch the surface. A protective film is often applied during shipping and handling which should be removed carefully.
Q4: What packaging do you use for export to ensure the coil surface is not damaged?
A: We use robust, seaworthy packaging. Coils are typically wrapped with waterproof paper or plastic film, then secured with steel straps on a wooden pallet or placed inside a strong wooden case. For mirror finishes, we often add an extra layer of protective film directly on the steel surface to prevent scratches during transit.
Q5: What is the meaning of "2B", "BA", and "8K" in surface finishes?
A: These are industry standard designations. 2B is a cold-rolled, matte finish with a light gray appearance. BA (Bright Annealed) is a bright, reflective finish achieved by annealing in a controlled atmosphere. 8K refers to a mirror polish, where the "K" relates to the level of reflectivity (akin to camera lens quality), with 8K being very high clarity.
Q6: Do you provide material test certificates with the shipment?
A: Yes, we can provide Mill Test Certificates (MTC or MTR) upon request. These certificates detail the chemical composition and mechanical properties of the supplied batch, verifying that the material meets the specified grade standards (e.g., ASTM, JIS).
Q7: What is the lead time for an order?
A: Lead time depends on the order quantity, grade, size, and finish. Standard grades and sizes may have shorter lead times or be available from stock. For customized orders, typical production time ranges from 15 to 30 days after order confirmation, plus shipping time. We provide a firm lead time estimate with every quotation.
Q8: How do I choose between cold-rolled and hot-rolled coils for my project?
A: Choose cold-rolled if your application requires precise thickness tolerances, a smoother surface finish (like 2B or BA), higher strength, or better surface aesthetics. Choose hot-rolled for applications where dimensional precision is less critical, for parts that will undergo significant further processing (like forging), or where cost is a primary driver for thicker gauges.
