FAQs:

Question: What is the material of this medical - grade stainless steel chamfered tube? Does it meet the medical industry standards?

Answer:​ Our medical - grade chamfered tube is made of 316L medical - grade stainless steel​ (304 or 316L can be customized according to customer needs). This material has excellent biocompatibility, complies with medical - grade material standards such as ISO 10993 (biocompatibility assessment), ASTM F138 (stainless steel for surgical implants), and domestic GB/T 1220. It can be safely used in medical device scenarios that come into contact with the human body or body fluids, with no risk of heavy metal precipitation.

Question: How is the machining accuracy of the chamfer? Will there be burrs affecting the use?

Answer:​ We adopt CNC precision numerical control processing + automatic deburring process. The chamfer angle (e.g., 15°/30°/45° can be customized) and size tolerance are strictly controlled within ±0.05mm. After chamfering, the tube end edges are smooth and round, without burrs or scratches, which can avoid scratching the inner wall of medical pipelines, catheters or instruments, and improve the smoothness during assembly.

Question: Can the outer diameter, inner diameter, length, and chamfer angle of the product be customized? What is the minimum order quantity?

Answer:​ We support full - specification customization: outer diameter (φ0.5mm - φ50mm), inner diameter (opened according to demand), length (1mm - 500mm), chamfer angle (15° - 60° optional, non - standard customization is also available). The minimum order quantity (MOQ) is usually 100 pieces. If you have an urgent small - batch demand, you can contact the sales team to evaluate whether small - batch trial production is supported.

Question: How is the surface finish of the tube? Will it retain impurities that affect medical cleanliness?

Answer:​ The product surface is polished by mirror polishing or matte treatment, with a roughness Ra≤0.8μm (can be increased to Ra≤0.4μm on request). There is no oil, no oxide scale, and no machining debris on the surface, meeting the cleanliness requirements of the medical industry. At the same time, the dense surface of the stainless steel material is not easy to adsorb bacteria or pollutants, which is convenient for subsequent medical cleaning (such as ultrasonic cleaning, high - pressure water gun flushing).
