Stainless Steel Medical Injection Needle Tube ISO9626 TP304 TP316L 30G

ISO 9626 is an international standard for stainless steel tubes, specifically focused on the manufacturing and dimensions of stainless steel tubes used for medical applications, such as in the production of hypodermic needles and other medical instruments. This standard specifies the requirements for stainless steel tubes, ensuring they meet specific mechanical properties, corrosion resistance, and dimensional tolerances.

The key aspects of ISO 9626 are:

1. Material: It outlines the type of stainless steel that should be used, typically austenitic stainless steel, which is known for its excellent corrosion resistance.

2. Dimensions: It provides the specific tolerances for tube dimensions, including wall thickness, outer diameter, and length, ensuring uniformity and suitability for medical applications.

3. Mechanical Properties: It covers the strength, hardness, and flexibility required for medical devices to ensure they perform safely under stress or manipulation.

4. Surface Finish: It specifies the surface quality to avoid contamination, which is critical in medical applications.

Capillary tubes are typically made from stainless steel.

1. Extrusion:

   A metal billet is forced through a die to create a long, narrow tube.

2. Drawing:

   The extruded tube is then pulled through progressively smaller dies to reduce the diameter.Annealing may be used between draws to soften the metal.

3. Coiling:

   Tubes are coiled into spirals or straight lengths depending on usage.
