Stainless Steel Gas Struts
What are Stainless Steel Gas Springs?
Stainless steel gas springs are sealed, nitrogen-filled struts that provide smooth lifting, lowering, and support for moving parts.
They offer better corrosion resistance than standard carbon steel gas springs, making them suitable for marine, food-processing, medical, outdoor, and industrial applications.
What Is the Difference Between 304 and 316L Stainless Steel Gas Struts?
For stainless steel gas struts used in marine, coastal, food-processing, or medical environments, material selection directly affects corrosion resistance and service life. The table below compares 304 and 316L stainless steel for common application conditions.
| Feature | 304 Stainless Steel | 316L Stainless Steel (GASTAC Standard) |
|---|---|---|
| Molybdenum Content | None | About 2%, helping improve corrosion resistance |
| Saltwater Resistance | Limited; risk of pitting in marine environments | High; suitable for marine-grade applications |
| Chemical Resistance | Moderate | Excellent against chlorides and harsh environments |
| Ideal Applications | Indoor furniture, kitchens, and general equipment | Boats, food plants, medical equipment, and coastal use |
316L Stainless Steel Gas Struts
316L stainless gas struts are engineered for maximum corrosion resistance, making them the top choice for marine, coastal, chemical, and medical environments. With enhanced durability against saltwater, chemicals, and harsh conditions, they deliver extended service life and reliable performance even in the toughest applications. For industries where safety and longevity are critical, 316L offers unmatched quality.
304 Stainless Steel Gas Struts
304 stainless gas struts provide an excellent balance of performance and cost-effectiveness. With strong resistance to everyday rust and oxidation, they are widely used in outdoor equipment, industrial machinery, and food-grade applications. Their durability and hygienic properties make them ideal for environments that require cleanliness and reliability, while offering an economical choice for most standard projects.
Stainless Steel Gas Strut Specifications
When selecting or replacing a gas spring, it is important to measure the key dimensions accurately. Start with the Rod Diameter and Body Diameter, which determine the strength and load capacity of the gas spring. Next, measure the Stroke, which is the distance the rod can travel between the fully compressed and fully extended positions. Finally, record the Extended Length, which is the total length of the gas spring from the center of one end fitting to the other when fully extended. By following these steps, you can ensure the correct specifications for your application and achieve reliable performance.
