Low Carbon 316L Stainless Steel Thin Strips 0.05-0.5mm Stainless Steel Foil

316L Thin Precision Stainless Steel Strip

Target Industry: Electronics & Micro-Engineering

Key Specifications:

• Thickness Range: 0.02mm – 0.5mm (20μm – 500μm)

• Width Tolerance: ±0.01mm (Custom slitting up to 200mm width)

• Surface Roughness: Ra ≤ 0.1μm (Superior flatness for micro-components)

• Temper: Extra-Soft Annealed (Hardness: HV 130-150)

• Flatness: ≤ 0.1mm/m (Laser-leveled for critical alignment)

Enhanced Properties:

✅ Zero Cross Contamination:

• Processed in dedicated cleanroom facilities (ISO Class 7)

• Oils/greases replaced with VOC-free volatiles
  ✅ Micro-Edge Quality:

• Burr-free edges (EFC ≤ 0.005mm) via precision shear cutting

• Edge cracks eliminated through controlled annealing
  ✅ Stability Under Stress:

• Consistent CTE (16.5 μm/m·°C) for thermal management substrates

• Negligible magnetic permeability (<1.02 μ)

Unique Certifications:

• Traceability: Full lot traceability with embedded laser QR coding
• Purity: Interstitial Element Control (O ≤ 30ppm, N ≤ 200ppm)
• Compliance: RoHS 3, REACH, and ISO 13485 (Medical Device Annex)

Applications:

• Flexible printed circuit board (FPCB) shielding layers
• Hermetic seals for micro-electromechanical systems (MEMS)
• Surgical robotic actuator springs
• Thin-film deposition substrates

Packaging:

• Vacuum-sealed between static-dissipative PET films
• Mounted on 300mm anti-telescoping cores
• Humidity indicator included in nitrogen-flushed drums

Note: Custom passivation (citric acid or nitric acid) available per ASTM A967.
