Description
ASTM A269 SUS304 Medical Grade Capillary Tubes, Corrosion Resistant,Precise for Hypodermic Needles, Medical Devices
ASTM A269 SUS304 medical capillary tubing is a precision micro-tube manufactured according to ASTM A269 standards, made of SUS304 stainless steel, and specifically designed for medical applications.
304 stainless steel is widely recognized for its good biocompatibility. Thanks to its excellent corrosion resistance and biocompatibility, capillary tubes play a crucial role in the medical field.
Medical Needle Application Selection Notes: TP304 is commonly selected for general medical needle applications requiring good strength, ductility, and corrosion resistance.
TP304L offers enhanced weldability due to its lower carbon content, making it ideal for welded needle assemblies where post-weld annealing is not performed.
304/304L Dual Certified tubing is also available, meeting both composition requirements, providing maximum flexibility for medical device manufacturing.
Let me know if you need additional data such as surface finish requirements (BA/EP) or dimensional tolerances for medical capillary tube applications.
