ASTM A312 TP316L Austenitic Seamless Stainless Industrial Steel Pipe

Superior Performance Characteristics

• Superior All-Round Corrosion Resistance: Molybdenum-enhanced alloy system outperforms 304/304L; highly resistant to pitting, crevice corrosion, intergranular corrosion and general corrosion in chloride-rich, acidic, alkaline, saltwater and harsh chemical media.
• Low-Carbon Welding Advantage: ≤0.03% carbon content eliminates sensitization during welding/thermal processing; no post-weld heat treatment (PWHT) required for most industrial applications, reducing fabrication costs and time.
• Excellent High Pressure & Temperature Performance: Designed for high-pressure piping systems; maintains stable mechanical properties at continuous high temperatures up to 815°C and intermittent use up to 870°C, suitable for high-pressure steam and thermal fluid transfer.
• Outstanding Mechanical Strength: Tensile strength ≥485 MPa, yield strength ≥170 MPa, elongation ≥40%; 100% seamless structure avoids weld seam weaknesses, with higher pressure-bearing capacity and anti-fatigue performance.
• Precise Dimensional Tolerance: Cold drawn/hot finished seamless process, uniform wall thickness, smooth inner/outer surface; low flow resistance, suitable for precision fluid and gas transfer in industrial piping systems.
• Excellent Weldability & Formability: Easy to weld via TIG/MIG/MMA processes; good cold/hot formability for bending, flanging, expanding and threading, adaptable to various on-site fabrication needs.
• Durable & Oxidation Resistant: Resists high-temperature oxidation and chemical aging in harsh industrial environments; no rust or material degradation, significantly reducing maintenance and replacement costs.
• Sanitary Optional Surface: Food-grade polished finish (2B/No.4/8K) available, no heavy metal leaching, meets GMP/3A sanitary standards for food, beverage and pharmaceutical applications.

Additional Product Advantages
