Glossary

The following are terms that you may not be familiar with:

Baking:

Heating of electroplated springs to relieve hydrogen embrittlement.

Elastic Limit:

Maximum stress subjected a material may be without permanent set.

Heat setting:

Fixturing a spring at elevated temperature to minimize loss of load at operation temperature.

Hydrogen Embrittlement:

Hydrogen absorbed in electroplating or pickling of carbon steels, tending to make the spring material brittle and susceptible to cracking and failure.

Passivating:

Acid treatment of stainless steel to remove contaminants and improve corrosion resistance.

Residual Stress:

Stresses induced by set removal, shot peening, cold working, etc. These stresses may/may not be beneficial, depending on the application.

Stress Relieve:

Subject springs to low-temperature heat treatment to relieve stresses.

Shot Peening:

A cold-working process in which the material surface is peened to induce compressive stresses and thereby improve fatigue life.
