What does stretch spring line diameter tolerance mean? The line diameter will be displayed in the search results. Standard tolerances for wire are related to material specifications (e.g. DIN,EN, etc.). The wire diameter will change slightly during winding. The spring is right-handed. Spring head type British head form a coil, two loops in the same plane.

The German head has two angles: 0 degrees and 90 degrees. If you want the spring head to close completely, use the British one. If you want the spring to be more durable, use the German one.

In the final process, the compression spring made from the qin steel wire should be treated with oil burner after production to avoid corrosion. To increase corrosion resistance, you may use galvanized steel wire (which can remain corrosion-free in alkaline fog for 96 hours) or stainless steel wire such as ISI302, which can remain corrosion-free in alkaline fog for 200 hours). Magnetic stainless steel and qin steel wire is different, is slightly magnetic.

Can springs work under load? In order for the spring to work properly, avoid applying forces beyond the maximum load the spring can bear. Otherwise the spring will lose its mechanical properties, such as free length changes.
