How does hardware spring work s

Want hardware spring to be able to work smoothly under high temperature, must it have compressive strength to resist very good laxity, heat resistance and its ability to resist oxidation, also want to have certain ability to resist corrosio...


The reason why the spring slope

The steel wire used to make the spring is 1.5, the outer diameter of the spring is 8.1, and the height is 12.3(after full pressure, the height is 13 without full pressure). After many debugging, it is found that this may be the residual def...
