316L round bar Material Composition & Key Properties
Crafted from ultra-low carbon austenitic stainless steel (C ≤0.030%12), 316L round bars excel in corrosion resistance and weldability. Their optimized chemistry includes:
- Cr (16.0–18.0%): Forms a robust passive layer for superior corrosion resistance13.
- Ni (10.0–14.0%): Enhances ductility and high/low-temperature stability12.
- Mo (2.0–3.0%): Boosts resistance to pitting and crevice corrosion in chloride-rich environments
Superior Machinability & Fabrication Flexibility
316L round bars are engineered for seamless processing:
- Welding: No post-weld annealing required, ensuring crack-free joints with retained corrosion resistance56.
- Forming: Excellent cold workability for bending, stamping, and machining into complex geometries25.
- Surface Finish: Polished, sandblasted, or pickled options available for aesthetic and functional needs5.
The low carbon content minimizes carbide precipitation during heat treatment, preserving structural integrity13.
Versatile Applications Across Industries
Trusted globally for critical applications, 316L round bars are ideal for:
- Chemical & Petrochemical: Reactors, pipelines, and valves exposed to acids/alkalis25.
- Marine Engineering: Ship components, offshore platforms, and desalination systems26.
- Medical & Food Processing: Surgical tools, storage tanks, and hygienic equipment25.
- High-Temperature Environments: Furnace parts and heat exchangers (avoid sustained use above 800°C)5.
