ASME SA213 TP316L Stainless Steel Tube 316L Tube ASTM A213 TP316L

Guanyu Tube is specialized manufacturer of SA213 TP316L Stainless Steel Tubes in China with reliable quality and good price.

ASME SA213 TP316L Stainless Steel Tubes main Features

• Superior Corrosion Resistance: Improved resistance to chlorides, acids, and pitting/crevice corrosion due to 2-3% Mo addition.
• Ultra-Low Carbon Content: Max 0.025% C (lower than standard 316L) to further reduce carbide precipitation during welding.
• High-Temperature Stability: Performs well in continuous service up to 870°C (1,598°F) and intermittent service up to 925°C (1,697°F).
• Non-Magnetic: Austenitic structure remains non-magnetic after annealing.
• Dual Certification: Meets both TP316L and TP316 requirements for flexibility.

ASME SA213 TP316L Stainless Steel Tubes Heat Treatment

• Solution Annealing: 1,040–1,150°C (1,904–2,102°F), followed by rapid cooling (water quenching).
• Holding Time: Minimum 30 minutes at temperature, adjusted for tube thickness.
• Purpose: Eliminate carbide formation, ensure homogeneity, and optimize corrosion resistance.

Precaution for Use of ASME SA213 TP316L Stainless Steel Tubes

• Welding: Use ultra-low-carbon filler metals (e.g., ER316L) to maintain corrosion resistance. Control interpass temperature <150°C (302°F).
• Sensitization Avoidance: Avoid prolonged exposure to 425–860°C (797–1,580°F) to prevent Mo-rich phase precipitation.
• Chloride Exposure: Limit use in stagnant chloride solutions >60°C (risk of SCC).
• Surface Contamination: Prevent iron/steel particle embedment (use dedicated tools).
• Post-Fabrication Cleaning: Passivate with nitric acid to restore oxide layer.

Application of ASME SA213 TP316L Stainless Steel Tubes

• Marine Environments: Seawater piping, desalination plants.
• Chemical & Petrochemical: Reactors, heat exchangers in HCl/H2SO4 environments.
• Pharmaceutical: Ultra-clean systems requiring corrosion resistance.
• Nuclear/Power Plants: Secondary cooling systems.
• Pollution Control: Flue gas scrubbers.
