Grade 316 Stainless Steel Pipe / Tube
Grade 316 stainless steel tubing is the premier choice for transporting fluids and gases in the most hostile environments. Known as Marine Grade stainless, Grade 316 (EN 1.4401/1.4404) contains added molybdenum, which protects against pitting and crevice corrosion that standard grade 304 simply cannot match.
Whether you are designing an offshore desalination system, a pharmaceutical production line, or high-end coastal balustrades, our grade 316 stainless steel pipes deliver the ultimate combination of structural strength and chemical resilience.

Key Characteristics of Grade 316 Stainless Tubing
- Exceptional Chloride Resistance: Designed to withstand constant exposure to sea spray, salt water, and de-icing salts.
- Chemical & Acid Durability: Highly resistant to corrosive cleaning agents and industrial chemicals, essential for hygienic industries.
- Superior Mechanical Strength: Maintains higher creep strength and mechanical properties at elevated temperatures compared to Grade 304.
- Hygienic Surface Finish: Non-porous and easy to sterilise, making it safe for food, beverage, and medical applications.
- Weldability: Offers excellent fusion welding characteristics (TIG and MIG), ensuring reliable, leak-proof joints in pressurised systems.
Common Applications of Grade 316 Stainless Tubing
- Marine & Offshore Engineering: Saltwater cooling systems, exhaust manifolds, offshore oil rig piping assemblies, and coastal handrails.
- Pharmaceutical & Chemical: Process piping for transporting aggressive chemicals, solvents, and high-purity medical-grade fluids.
- Food & Drink Production: Fluid lines handling highly acidic ingredients (such as vinegar or citrus juice) and dairy processing lines where salt is present.
- Water Treatment: Desalination plant pipework, reverse osmosis modules, and wastewater filtration infrastructure.
- High-End Architecture: Structural column jackets, balustrades, and aesthetic features for buildings located in coastal or high-pollution urban areas.
