• Corrosion resistance – Resist corrosion in atmospheric and pure water environments and in most acids, alkaline solutions, and chlorine–bearing environments.
• Hygiene – The easy cleaning ability of stainless makes it the first choice for strict hygiene conditions, such as in hospitals, kitchens, and food processing plants.
• Aesthetic appearance – Stainless steel’s bright, easily maintained surface provides a modern and attractive appearance.
• Long–term value – When the total life cycle costs are considered, stainless is often the least expensive material option.
• Nonmagnetic – Stainless steel grades used for gas spring manufacturing are not magnetic.

As we can see from the graphic of a actual case from one of our customer, the pink curve represents the force change from the gas spring been compressed, then extension back. In the process, there are 4 force values, F3, F4, F2, F1. These forces are measured 5 mm before the end of the movements.

The K-factor (force ratio) is Fb/Fa.

The diviation between F3 and F1 is 2 times of friction froces when positon moves inside the tube.
