ASTM A269 TP316L Stainless Steel Seamless Tubing For Industrial Use

Strictly compliant with ASTM A269 & TP316L standard, ultra-low carbon content for enhanced intergranular corrosion resistance, the specific component ratio is as follows:

1. Exceptional Corrosion Resistance: Molybdenum-added formulation outperforms 304/304L; highly resistant to pitting, crevice corrosion and general corrosion in acidic, alkaline, saltwater and chloride-rich environments.
2. Low-Carbon Intergranular Corrosion Resistance: ≤0.03% carbon content eliminates sensitization during welding/annealing, no post-weld heat treatment required for most applications.
3. Excellent Mechanical Properties: High tensile strength (≥485 MPa), yield strength (≥170 MPa) and elongation (≥40%); maintains toughness and ductility at both low and moderate temperatures.
4. Smooth Surface & High Precision: ASTM A269 standard seamless production, annealed & pickled (A/P) or bright annealed (BA) surface; uniform wall thickness, tight dimensional tolerance, no weld defects.
5. Good Weldability & Formability: Easy to weld via TIG/MIG/MMA processes; excellent cold/hot formability for bending, flanging, and fabrication without cracking.
6. High Temperature Stability: Maintains structural integrity and performance in continuous high-temperature working environments (up to 870°C for intermittent use, 790°C for continuous use).
7. Sanitary & Non-Toxic: Food-grade surface finish optional, no heavy metal leaching, meets sanitary standards for food, beverage and pharmaceutical processing.
