316 Seamless Tube & Round Metal Pipe, 3/8"(9.53mm) 12in Thin Wall 1.24mm

316 Stainless Steel Seamless Precision Tube This 316 stainless steel seamless tube is designed for high-precision, high-corrosion-resistance applications such as medical equipment, precision instrumentation, marine, food processing, pharmaceutical, and chemical industries. It is manufactured from genuine 316 (18-12-2.5) stainless steel with a chemical composition of Cr≥16%, Ni≥10%, Mo≥2%, providing excellent resistance to chloride pitting, crevice corrosion, salt spray, and harsh chemicals. Produced by seamless cold drawn process and fully annealed for uniform structure, no welds, high strength, good pressure resistance, excellent straightness and long service life. All sizes comply with ASTM A312, and tubes with outer diameter ≤ 3" also meet ASTM A269 instrumentation standard. With ultra-precision outer diameter tolerance ≤ ±0.13mm, this tube ensures high concentricity, stable dimension, easy machining and perfect assembly. Widely used in: Precision machining: shaft sleeves, rotating shafts, positioning pins Temperature measurement: thermocouple protection tubes, thermal resistance sleeves Fluid & gas transmission: capillary lines, chromatography columns, precision instrument lines Medical & industrial: dispensing needles, puncture needles, cannulas Marine, food, pharmaceutical, chemical, laboratory instruments, hydraulic and pneumatic systems Suitable for professional industrial and high-end precision equipment.

• 316 Stainless Steel – Marine & Medical Grade Made of genuine 316 (18-12-2.5) stainless steel with Mo≥2%. Superior chloride pitting, crevice corrosion and chemical resistance, significantly better than 304 in marine, salt, acid and harsh environments.
• Seamless Cold Drawn & Annealed – Ultra-Precision Tolerance Seamless cold drawn technology with full annealing. No weld seams, uniform structure, excellent pressure resistance. OD tolerance ≤ ±0.13mm, much tighter than industrial standard.
• Dual Standard Compliance: ASTM A312 & A269 (OD ≤ 3") Meets ASTM A312 general standard. OD ≤ 3" sizes also comply with ASTM A269 instrumentation grade, ideal for high-purity fluid systems, precision instruments and medical equipment.
