Product Overview
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.
Key Features
- 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
