316L stainless steel gas springs and struts are specialized motion control components engineered to thrive in corrosive, hygiene-critical, and demanding environments. Available in micro, standard, locking, and tension configurations, these units from Industrial Gas Springs combine the durability of 316L stainless steel with precision performance—making them indispensable for marine, food, pharmaceutical, medical, and petrochemical applications. This technical guide breaks down their key features, adjustability, applications, and selection tips to help you leverage their full potential.

Key Product Features

316L stainless steel gas springs stand out for their robust design and industry-specific enhancements:

1. 316L Stainless Steel Construction

• Both the body (pressure tube) and piston rod are crafted from 316L stainless steel—an alloy with molybdenum that delivers superior resistance to saltwater, chemicals, and frequent washdowns.
• Outperforms 304 stainless steel in harsh environments, withstanding chloride-rich settings (e.g., marine) and chemical exposure (e.g., petrochemical plants) without rust or degradation.

2. Food-Grade & Hygiene Compliance

• Stock units use USDA H1 food-grade oil, ensuring safety for applications where incidental contact with food, pharmaceuticals, or medical products is possible.
• Non-porous stainless steel surface and sealed design prevent bacterial growth, complying with FDA (food industry) and GMP (pharmaceutical/medical) standards.

3. Versatile Force & Stroke Ranges

• Standard Compression: Stroke lengths from 2 in (50.8mm) to 20 in (508mm), forces from 9 lb (40N) to 1,120 lb (4,982N) — suitable for most industrial and commercial loads.
• Micro Configurations: Lower forces (starting below 9 lb) and shorter strokes (under 2 in) — ideal for compact, lightweight applications (e.g., small medical devices, precision machinery).

4. Durability & Longevity

• Sealed design protects internal components (nitrogen gas and damping oil) from moisture and contaminants, ensuring reliable performance over 50,000+ cycles.
• Resists temperature extremes from -40°C to 80°C, adapting to indoor, outdoor, and industrial environments.

Adjustability & Custom Options

Flexibility is a core strength of these 316L gas springs, with features to tailor performance to your application:

1. Force Fine-Tuning

• Except for micro sizes, all units include a release valve that lets installers bleed off small amounts of nitrogen gas to adjust force. This eliminates the need for precise upfront calculations.
• Industrial Gas Springs offers recharging services if too much pressure is released, extending the component’s usability.

2. Configuration Options

The product line covers four key configurations to match diverse needs:

• Micro Compression: Compact, low-force units for tight spaces (e.g., small access panels).
• Standard Compression: Versatile workhorses for lifting/lowering lids, doors, and guards.
• Locking: Secure positioning at any stroke point (rigid or elastic locking) — ideal for adjustable medical beds or marine seating.
• Tension: Pulling force for applications like closing hatches or retracting components.

3. Custom Manufacturing

For unique requirements (e.g., non-standard stroke, force, or end fittings), custom units are available subject to minimum order quantities. Industrial Gas Springs can tailor materials, dimensions, and features to meet specific environmental or performance needs.

Typical Applications

316L stainless steel gas springs excel in environments where standard steel or lower-grade stainless steel fails. Here are their most common uses:

1. Marine Industry

• Boat hatches, engine covers, and storage lockers — resist saltwater corrosion and harsh marine conditions.
• Offshore platform equipment and submarine access doors — durable under high humidity and salt spray.

2. Food & Beverage Processing

• Sanitary access panels, conveyor covers, and packaging machinery — food-grade oil and easy-to-clean surfaces comply with hygiene standards.
• Refrigerated display cases and food storage lids — corrosion-resistant in cold, damp environments.

3. Pharmaceutical & Medical

• Medical beds, exam tables, and diagnostic equipment — hygiene-compliant and resistant to cleaning chemicals (e.g., disinfectants).
• Pharmaceutical processing machinery — GMP-compliant, with no risk of contaminating products.

4. Petrochemical & Industrial

• Chemical plant access doors and equipment guards — resist exposure to corrosive fluids and gases.
• Outdoor industrial machinery — withstands rain, humidity, and temperature fluctuations without rust.

5. Specialty Vehicles

• RV awnings, marine vessel seating, and emergency vehicle storage — durable in mobile, harsh environments.

Selection Tips for 316L Stainless Steel Gas Springs

To choose the right unit for your application, follow these key steps:

1. Define Core Requirements

• Force: Calculate required force using ( F = \frac{\text{Load Weight (N)} \times \text{Distance to CoG}}{\text{Distance to Mount}} ), then select a unit with a force range that accommodates fine-tuning (add 10% buffer).
• Stroke: Measure the travel distance (e.g., a 10 in hatch opening needs a 10 in stroke) — ensure the unit’s stroke matches or exceeds this value.
• Configuration: Choose compression (lifting/supporting), locking (positioning), tension (pulling), or micro (compact) based on function.

2. Validate Environmental Compatibility

• Confirm 316L stainless steel is required (e.g., saltwater or chemical exposure) — avoid over-specifying with 316L if 304 suffices (to reduce cost).
• For food/medical use, verify USDA H1 oil and hygiene certifications.

3. Check End Fittings & Mounting

• Select end fittings (threaded, ball sockets, eyelets) that match your mounting hardware — ensure fittings are also 316L stainless steel to prevent galvanic corrosion.
• Follow manufacturer guidelines for orientation (typically rod-down to keep oil at seals, extending service life).

4. Leverage Adjustability

• Opt for units with release valves if force precision is critical — this allows on-site tuning without replacing the entire spring.

Why Choose 316L Stainless Steel Over Other Materials?

• Corrosion Resistance: Outperforms 304 stainless steel and carbon steel in saltwater, chemicals, and washdown environments.
• Hygiene: Food-grade oil and non-porous surfaces make it the only choice for food/pharmaceutical/medical applications.
• Durability: Longer service life in harsh conditions, reducing replacement frequency and maintenance costs.

Final Considerations

316L stainless steel gas springs and struts are the gold standard for demanding environments where corrosion resistance, hygiene, and reliability are non-negotiable. Whether you’re outfitting a marine vessel, food processing line, or medical equipment, these units deliver consistent performance and long-term value.
