As a leading manufacturer with a modern facility in Wuxi, Jiangsu, Wuxi Yansheng Technology Co., Ltd. specializes in producing high-quality BA Bright Annealed Stainless Steel Strips in grades 301 and 304. Established in 2017, we leverage our expertise and advanced precision slitting technology to deliver metal strips that meet the stringent demands of diverse global industries. Our commitment to excellence is reflected in our comprehensive quality management systems, ensuring every strip offers superior surface finish, dimensional accuracy, and consistent mechanical properties for your critical applications.
Our BA Bright Annealed Stainless Steel Strips are engineered for performance and aesthetics. The bright annealing process not only delivers a smooth, reflective, and clean surface ideal for visible applications but also enhances the material's corrosion resistance and removes internal stresses. Combined with our precision slitting capabilities, we guarantee strips with exceptionally tight width tolerances and burr-free edges, which are crucial for automated feeding and subsequent forming processes.
Key Features & Advantages:
Superior Surface Quality: The BA finish provides a mirror-like, pristine surface that is free from scale and oxidation, reducing or eliminating the need for secondary polishing.
Enhanced Corrosion Resistance: The annealing process in a controlled atmosphere prevents surface carburization, preserving the inherent corrosion resistance of grades 301 and 304.
Excellent Dimensional Consistency: Our state-of-the-art precision slitting lines ensure uniform width and camber control, critical for high-volume stamping and fabrication.
Wide Range of Tempers: We supply strips in various tempers from Soft to Full Hard, allowing you to select the optimal balance of formability and strength for your specific part.
Reduced Contamination Risk: The clean BA surface is ideal for applications in electronics, medical devices, and food processing equipment.

Frequently Asked Questions (FAQ)
Q1: What is the main difference between BA finish and a standard 2B finish?
A: A BA (Bright Annealed) finish is achieved by annealing the stainless steel in a controlled hydrogen-nitrogen atmosphere, resulting in a smooth, reflective, and scale-free surface directly from the mill. A standard 2B finish is matte, slightly reflective, and may have a light oxide layer. BA is cleaner and brighter, often used where appearance and cleanliness are priorities.
Q2: Can you supply strips in tempers other than those listed?
A: Yes. While Soft, 1/4H, 1/2H, 3/4H, and Full Hard are standard offerings, we can customize the mechanical properties, including tensile strength and yield strength, to meet specific application needs. Please provide your detailed specifications for a quote.
Q3: What are the typical lead times for custom slit orders?
A: Lead times depend on the order quantity, material grade, and specifications. For standard grades and sizes, production can often be completed within 2-4 weeks. We provide estimated timelines upon order confirmation.
Q4: How do you ensure precision and consistency in slitting?
A: We utilize advanced precision slitting lines equipped with digital controls, tension management systems, and high-quality tooling. Our process includes in-line inspection to monitor width, camber, and edge quality continuously, ensuring every coil meets strict tolerance requirements.
Q5: What packaging do you use to protect the BA surface during transit?
A: To prevent scratches and contamination, coils are typically wrapped with multiple layers of waterproof paper or plastic film. They are then securely fastened on wooden pallets with steel strapping. Special packaging like VCI (Vapor Corrosion Inhibitor) paper is available upon request for extra corrosion protection.
Q6: Are your products suitable for food contact or medical applications?
A: Our BA strips, particularly in grade 304, are widely used in these industries due to their clean, scale-free surface and excellent corrosion resistance. However, final suitability depends on the specific application and regulatory requirements. We recommend consulting relevant standards and can provide material certificates for traceability.
Q7: Can you provide material test reports?
A: Yes. We can provide standard Mill Test Certificates (MTCs) that detail chemical composition and mechanical properties. Additional testing reports (e.g., surface roughness, hardness mapping) are available upon request.
Q8: Do you offer toll processing or slitting of customer-supplied coils?
A: This service may be available subject to capacity and material compatibility. Please contact our sales team with your coil details and slitting requirements for evaluation.
