ASTM A269 TP316L Stainless Steel Seamless Tube For Heat Exchanger
ASTM A269 is a specification by the American Society for Testing and Materials for seamless and welded austenitic stainless steel tubing used in corrosion-resistant and high-temperature service. The TP316L grade refers to a low-carbon variant of Type 316 stainless steel, optimized for welding and harsh environments.
Superior corrosion resistance in acidic/chloride environments (vs. 304/316).Enhanced weldability due to low carbon content.High strength and durability at elevated temperatures.Smooth, seamless structure ideal for high-pressure applications.
Chemical Composition:
Chromium (Cr): 16–18% (provides oxidation/corrosion resistance).
Nickel (Ni): 10–14% (stabilizes austenitic structure, enhancing ductility and toughness).
Molybdenum (Mo): 2–3% (improves resistance to pitting/crevice corrosion in chloride environments).
Carbon (C): ≤0.03% (low carbon minimizes carbide precipitation during welding).
Other elements: Manganese (≤2%), Silicon (≤0.75%), Phosphorus (≤0.045%), Sulfur (≤0.03%), Iron (balance).
Mechanical Properties:
Tensile Strength: ≥70 ksi (485 MPa).
Yield Strength: ≥25 ksi (170 MPa).
Elongation: ≥40% (in 2 inches).
Hardness: ≤90 HRB (Rockwell B) or ≤200 HB (Brinell).
Density: 8.0 g/cm³.
Melting Point: ~1375–1400°C.
Applications:
Pharmaceutical/Biotech: Sterile tubing for process systems (autoclave compatibility).
Chemical Processing: Handling acids, solvents, and corrosive chemicals.
Oil & Gas: Offshore platforms (resists seawater/sour gas).
Food & Beverage: Hygienic transfer lines (meets FDA/USDA standards).
Marine: Heat exchangers, desalination plants (saltwater resistance).
Medical Devices: Implants/surgical tools (biocompatibility, sterilizability).
Nuclear: Coolant systems (radiation/thermal fatigue resistance).
Heat Exchangers: High-temperature condensers and boilers.
