TP 304L Stainless Steel Capillary Tube: Seamless Austenitic Stainless Steel Pipe for Medical Applications
Material Specification
TP 304L stainless steel is a low-carbon version of the 304 grade, offering excellent corrosion resistance, formability, and weldability. It is particularly suitable for applications requiring a high degree of cleanliness and precision, such as in the medical field.
Key Features
- Corrosion Resistance: Excellent resistance to a wide range of atmospheric environments and many corrosive media.
- Low Carbon Content: Reduces the risk of carbide precipitation during welding, enhancing weldability.
- High Strength: Maintains strength at high temperatures.
- Non-Magnetic: In the annealed condition, it is non-magnetic, which is beneficial for certain medical applications.
- Biocompatibility: Safe for use in medical devices and surgical instruments.
