Ultra-Thin Stainless Steel Strip, 0.05mm Precision, High Flexibility, AISI 304L

Ultra-Thin Stainless Steel Strip (AISI 304L) with a precision thickness of 0.05mm and exceptional flexibility is engineered for high-tech industries requiring micron-level accuracy and reliable performance under dynamic stress. Manufactured through advanced cold-rolling and annealing processes, this strip retains the corrosion resistance of 304L stainless steel while achieving unmatched thinness (±0.005mm tolerance) and bendability (180° folds without cracking). Ideal for microelectronics, medical implants, and precision instrumentation, it complies with ASTM A240 and ISO 13485 standards, ensuring material consistency and biocompatibility. The ultra-smooth surface finish (Ra ≤0.05μm) further enhances its suitability for applications demanding minimal friction or contamination risks.
