How to judge the quality of stainless steel gas spring

Stainless steel gas springs are parts that can realize functions such as support, buffering, braking, height and angle adjustment. In construction machinery, it is mainly used for parts such as covers and doors.

Stainless steel gas spring is mainly composed of piston rod, piston, sealing guide sleeve, packing, pressure cylinder and joint. The pressure cylinder is a closed cavity filled with inert gas or oil and gas mixture, and the pressure in the cavity is several times or dozens of times the atmospheric pressure. Under the action of the gas spring, the movement of the piston rod is realized by the pressure difference on both sides of the piston. There are different structures and types of gas springs to meet different needs. Compressed gas springs are mainly used in construction machinery. This gas spring mainly plays an auxiliary role. It only has the shortest and longest working positions and cannot stop automatically during the stroke.

The preparation method of stainless steel gas spring includes the following steps:

-1. Smelting molten steel according to chemical composition requirements; hot rolling; annealing and pickling to obtain stainless steel slabs;

-2. Painting and drying; cold drawing; cleaning and drying with neutral activator; quenching;

-3. Tempering; painting and drying; drawing into stainless steel spring wire. This high-performance stainless steel spring wire is energy-saving, environmentally friendly, corrosion-resistant, highly elastic, and high-tough.
