High Tensile 316L Stainless Steel Bar for Marine Hardware, 1M
Length, EN 10088 Certified
EN 10088-certified 316L stainless steel bars (1-meter length) are engineered for marine and high-corrosion
environments. Designed with superior tensile strength and
exceptional resistance to chlorides, acids, and saltwater, these
bars are ideal for critical marine hardware applications. The 316L
grade’s low carbon content (≤0.03%) minimizes carbide precipitation
during welding, ensuring structural integrity in harsh conditions.
With a polished or mill-finished surface, these bars are
precision-cut to 1M lengths for seamless integration into offshore
platforms, shipbuilding components, and coastal infrastructure.

3. Competitive Advantages
① Superior Corrosion Resistance
The high molybdenum (Mo) content (2–3%) enhances resistance to
pitting and crevice corrosion in saltwater, outperforming standard
304/316 grades.
② EN 10088 Compliance
Rigorous adherence to European standards guarantees material
consistency, mechanical properties, and traceability for EU market
requirements.
③ Precision Manufacturing
Cold-drawn bars with tight dimensional tolerances (±0.1mm diameter)
ensure compatibility with marine hardware assemblies.
④ Welding & Fabrication Readiness
Low carbon content (316L) eliminates post-weld heat treatment
needs, reducing production time and costs.
⑤ Global Certifications
NACE MR0175 certification ensures suitability for sour gas
environments, while PED compliance supports pressure equipment
applications.
⑥ Custom Solutions
Available in diameters from 5mm to 50mm, with options for
threading, grooving, or heat treatment (e.g., solution annealing).
4. Key Applications
- Marine Shafts & Fasteners: Corrosion-resistant propeller shafts, bolts, and nuts for ships,
docks, and subsea equipment.
- Offshore Platforms: Structural components, railings, and connectors resistant to
seawater and atmospheric corrosion.
- Desalination Plants: Pump shafts, valve stems, and piping systems handling
high-salinity or chlorinated water.
- Chemical Processing: Reactor parts, heat exchangers, and tanks exposed to acidic or
alkaline solutions.
- Coastal Infrastructure: Reinforcements for bridges, piers, and tidal energy systems in
salt-laden environments.
- Oil & Gas: Subsea pipelines, drilling equipment, and fittings compliant with
NACE standards for H₂S environments.
