316 Stainless Steel Hinges

Even the strongest door fails if its hinges corrode under harsh conditions. Salt air, industrial chemicals, or constant exposure to moisture—these are the hidden enemies professionals battle daily. So the question is: how do you ensure hinges that won’t give in?

Waterson 316 stainless steel hinges are engineered for extreme durability, built from marine-grade 316 stainless steel. Resistant to rust, chemicals, and long-term wear, they outperform standard alloys where failure isn’t an option.

Built to last. Hinges that hold the line.

What is 316 Stainless Steel?

316 stainless steel belongs to the austenitic family of stainless steels. It contains molybdenum, which improves resistance to corrosion, especially in chloride-rich environments like coastal, poolside, or chemical facilities. In door hardware, this makes 316 stainless steel hinges the premium choice for durability and longevity.

Is 316 Stainless Steel Magnetic?

316 stainless steel is generally non-magnetic, thanks to its austenitic microstructure. Under heavy machining or cold-working, slight magnetism may appear, but it remains minimal. For hinge applications, this ensures consistent performance without unwanted magnetic pull or interference.

Which is Better: 304 or 316 Stainless Steel?

Both belong to the austenitic family, but the key difference is performance under harsh conditions.

  • 304 stainless steel (18–20% chromium, 8–10.5% nickel) is cost-effective and reliable for general indoor or outdoor use, provided chloride exposure is low.
  • 316 stainless steel (16–18% chromium, 10–14% nickel, 2–3% molybdenum) resists chloride corrosion far better, making it ideal for coastal, poolside, lab, or industrial settings.

When comparing 304 and 316 stainless steel, the distinction is simple:

  • Use 304 when conditions are moderate, cost is critical, and rust risk is minimal.
  • Choose 316 when long-term durability, harsh weather, and chemical resistance are non-negotiable.

Can 316 Stainless Steel Rust?

In normal conditions, 316 stainless steel hinges are highly resistant to rust. Even in environments with salt spray or acidic exposure, they resist pitting and surface breakdown better than 304 grade. While no alloy is 100% rust-proof, 316 stainless steel grades offer the highest protection for architectural hinges.

Outstanding Marine Performance of 316 Stainless Steel Hinges

While many hinges fail in coastal or chemical-rich environments, 316 stainless steel hinges are engineered to maintain strength, alignment, and appearance under the harshest conditions. Waterson’s 316 stainless steel hinges ensure performance where standard alloys fall short, with these features:

  • Self Closing: Integrated spring and damping function replaces bulky overhead closers.
  • Corrosion Resistant: SS316 withstands humidity, salt air, steam, and chemical exposure.
  • Heavy Duty: Rated for high door weights and intensive commercial use.
  • Adjustable Tension: Numerical panel allows fine-tuning of swing and closing force.
  • ADA Compliant: Meets <5 lbs opening effort, 33″ clearance, and 5-second close time.
  • Cycle Durability: ANSI/BHMA A156.17 Grade 1; tested to 1,000,000 cycles.
  • Warranty: 3-10 years reliability verified in coastal and high-salt conditions.
  • Streamlined Design: All performance is built directly into the hinge body.
  • Finish Options: Satin stainless, black, brass, and bronze available to match projects.

Whether specified for coastal resorts, industrial plants, or public facilities, 316 stainless steel hinges deliver the same precision and compliance professionals expect — with added durability against the toughest environments.
