ISO9626 SUS304 Welded Stainless Steel Medical Capillary Tube , Hypodermic Tube

ISO9626 SUS304 Welded Stainless Steel Medical Capillary Tube , Hypodermic Tube

The Welded Stainless Steel Capillary Tube is a high-precision, small-diameter and thin-walled tube that is manufactured from AISI304 / SUS304 / X5CrNi18-9 medical grade austenitic stainless steel strip through a longitudinal laser welding process. For medical applications, this medical capillary tubes are accorded with ISO9626 standard. Stainless steel 304 capillary tubes have ultra-precise dimension tolerance, excellent surface finish, high corrosion resistance, good biocompatibility, non-magnetic (austenitic structure), excellent formability, good strength, and cleanliness. These medical capillary tubes serve as a critical component in minimally invasive and high-precision surgical instruments. They can also cutted and processed into different types of medical needle tubes with different needle points. If the clients have needle or capillary tubes that need to custom, we can design according to they provided samples or drawings.
