Product Description
316L BA Stainless Steel Seamless Tube | Stress Relieved & No Oxide Shedding
WNRLN 316L BA stainless steel seamless tube features full bright annealing stress relief to eliminate fabrication-induced internal stresses. The controlled atmosphere process ensures zero oxide layer shedding, delivering a pristine surface for demanding industrial applications.
Key Features
- Stress Relieved: Complete bright annealing process removes residual stress from cold drawing, preventing stress corrosion cracking (SCC) and dimensional instability in service.
- No Oxide Layer Shedding: Inert atmosphere annealing produces a tight, adherent passive layer that will not flake, shed, or contaminate process media.
- Intergranular Corrosion Resistant: Low-carbon 316L (<0.03% C) with molybdenum addition prevents sensitization and grain boundary attack, even after welding.
- Wide Dimensional Range: Available from 6mm to 168mm OD with wall thickness up to 5mm, covering heat exchanger, boiler, and process piping requirements.
- ASTM A213 Certified: Meets ASTM A213 specifications for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes.
