316LVM Medical Grade Stainless Steel Pipes 1mm-10mm, Cost-Effective,Capillary precision tube for medical equipment
316LVM Medical Grade Stainless Steel Capillary Tubes (1mm–10mm OD) by Jiangsu China Steel Union Industrial Co., Ltd are ultra-precision, cost-effective solutions for minimally invasive medical devices and diagnostic equipment. Manufactured under ASTM F138 (ISO 5832-1) standards, these vacuum-melted (VM) tubes ensure exceptional biocompatibility, low inclusion content, and resistance to sterilization methods (autoclave, gamma radiation). The 316LVM grade, with controlled carbon (≤0.03%) and ultra-low impurities, minimizes ion leaching and thrombogenicity. Available in diameters from 1mm to 10mm, these capillary tubes feature ultra-smooth surfaces (Ra ≤0.2µm) and ±0.05mm tolerance for endoscopes, catheters, and drug delivery systems.
