Non-Magnetic Stainless Steel Tubes
Ultra-Thin Wall 316L Non-Magnetic Stainless Steel Tubing (Non-Annealed)
1. Product Description
Our ultra-thin wall 316L stainless steel tubes are engineered for specialized applications requiring a combination of high strength, minimal weight, and non-magnetic properties. These tubes are supplied in a Non-Annealed (Hard-Drawn) state to maintain maximum structural rigidity and tensile strength even at extremely low wall thicknesses.

4. Key Characteristics
Ultra-Thin Profile: Wall thicknesses as low as 0.1mm to 0.3mm allow for significant weight reduction without compromising the outer diameter requirements.
High Strength (Work Hardened): By skipping the annealing process, the material retains the hardness and tensile strength gained during cold drawing, preventing the tube from collapsing or deforming easily.
Strictly Non-Magnetic: 316L remains stable and non-magnetic even after cold working, making it essential for interference-sensitive environments.
Superior Corrosion Resistance: Excellent performance in acidic, alkaline, and high-chloride environments (Marine/Chemical).
Dimensional Stability: High precision on both OD and ID for seamless integration with precision seals or electronic components.
5. Application Scenarios
Precision Sensors: Protective housings for electromagnetic sensors where magnetic interference must be zero.
Aerospace & Defense: Lightweight ducting and structural components for weight-critical flight systems.
Medical Technology: Components for MRI-compatible devices and specialized surgical instruments.
Cryogenic Equipment: Thin-wall thermal breaks and conduits for liquefied gas systems.
High-End Electronics: EMI/RFI shielding sleeves for sensitive high-frequency signal transmission.
