In the field of outdoor equipment, the durability and reliability of gas springs directly affect the service life of the product. As the outdoor industry's requirements for equipment performance increase, stainless steel gas springs are gradually replacing ordinary gas springs and becoming the preferred solution for harsh environments. This article will analyze the core differences and applicable scenarios between the two.
1. Material and corrosion resistance: the key to outdoor durability
- Ordinary gas spring:
Usually made of carbon steel, with chrome plating or spray painting on the surface. It performs well in dry environments, but long-term exposure to moisture, salt spray or chemical corrosion environments (such as the seaside and industrial areas) is prone to rust and coating shedding, resulting in sealing failure and reduced support force.
- Stainless steel gas spring:
304 or 316 stainless steel is selected, which has excellent corrosion resistance and is especially suitable for marine equipment, outdoor furniture, engineering machinery and other scenarios. Experimental data shows that in salt spray tests, the life of stainless steel gas springs is more than 3 times that of ordinary gas springs.
Typical application comparison:
- Ordinary gas spring: indoor furniture, storage equipment
- Stainless steel gas spring: ship hatch, solar tracking bracket, outdoor billboard
2. Sealing performance: dealing with extreme temperature and pollution
- Ordinary gas spring:
Rubber seals are prone to aging and brittleness in high temperature (＞80℃) or low temperature (＜-20℃) environments, resulting in air leakage. The intrusion of sand, dust or muddy water will accelerate wear.
- Stainless steel gas spring:
It uses fluororubber (FKM) or PTFE seals, withstands the temperature range of -40℃ to 150℃, and has a dust and water resistance level of IP65 or above, which is suitable for equipment in deserts and high-cold areas.
3. Load and maintenance cost: long-term economic analysis
- Initial cost: The price of stainless steel gas springs is 30%-50% higher than that of ordinary models.
- Comprehensive benefits:
- Maintenance-free: Stainless steel materials do not require regular rust prevention.
- Low failure rate: In outdoor scenarios, the average annual replacement rate of ordinary gas springs is about 15%, while stainless steel models can be reduced to less than 5%.
