Exporter of ASTM A269 TP316L SS Clean BA Tubes
ASTM A269 316L austenitic ss tubes are the low‑carbon variant of grade 316, designed for general corrosion‑resistant applications. They are an ideal choice for environments requiring high purity and critical welding applications. If you need to purchase ASTM A269 TP316L clean BA tubes, GNEE can offer you professional procurement solutions.
The ASTM A269 316L clean BA tubes we supply are manufactured from low‑carbon 316L austenitic ss through cold drawing / cold rolling plus bright annealing (BA) under protective atmosphere. They are free of surface scale with inner‑surface roughness Ra ≤ 0.8 μm. In the solution‑bright‑annealed condition, our ss tubes feature a tensile strength ≥ 485 MPa and elongation after fracture ≥ 40 %, which enable smooth bending, coiling and flaring processes. Containing molybdenum element, the tubes resist chloride‑ion corrosion and can achieve more than 500 hours in neutral salt‑spray tests, suitable for instrument and clean‑medium working conditions.
GNEE's Value‑Added Services
1.Deep‑processing: Custom cutting, beveling, coiling
2.Surface treatment: Pickling, polishing
3.Custom export packaging, technical consultation & sample support

FAQ
Yes. Our ASTM A269 TP316L BA tubes have consistent dimensions and clean ID/OD surfaces ideal for orbital and autogenous welding.
2.What's the difference between 316 and 316L sS Tube?
The main difference between 316 and 316L ss is their carbon content. Grade 316 has a maximum carbon content of 0.08%, while 316L (the "L" stands for low carbon) has a maximum limit of 0.03%. This small change in carbon affects their strength, high-temperature performance, and behavior when welded
3.What is TP316L material made of?
TP316L is a low-carbon, molybdenum-bearing austenitic stainless steel [0.12] designated by the prefix TP for high corrosion and welding performance. Key characteristics include low carbon content (max 0.03%), molybdenum addition (2-3%), and austenitic structure.
