Description de produit

Ultra-Low Inner Wall Roughness Stainless Steel BA Tube — ASTM A269 TP316L Seamless

YUHAO presents its premium ASTM A269 TP316L seamless bright annealed (BA) stainless steel tube, engineered specifically for applications demanding ultra-low inner wall roughness. Available in outer diameters from 6mm to 630mm with customizable wall thicknesses, this tube delivers exceptional surface quality through a rigorously controlled hydrogen atmosphere bright annealing process.

▶ Key Product Advantages — Ultra-Low Inner Wall Roughness

  • Inner wall roughness Ra ≤ 0.25μm (standard), 0.2μm achievable upon request
  • Multi-pass cold drawing with proprietary mandrel technology for ultra-smooth ID finish
  • Surface profilometer verified on every production batch with full traceability reports
  • Minimized flow resistance and particle entrapment for high-purity fluid and gas systems
