Spring material depends upon the application and the working environment of the springs. Several coatings are available which can provide corrosion resistance for the wires that themselves would not resist corrosion. These coatings include Powder coating, Electroplating, Phosphating. The coated spring produced by this type of material is generally cheaper than the spring produced from Stainless St...

d - wire diameterD - mean diameter, the diameter of the spring as measured at the wire centerlineID - inside diameter, D-dOD - outside diameter, D+dNa - number of active coilsNt - total coils, active coils plus any inactive coils. For a spring with closed ends, Nt=Na+2FL - free length, the spring length with no load appliedP, F - load or force, the force exerted by the spring under a given deflect...

Hot-wound springs are made from larger diameter material. Due to the size of the wire, the spring must be heated up to a hot state, then formed using an annealed (soft) material, and heat-treated afterwards. Cold-wound springs are smaller in size and are formed in a cold state using pre-tempered material.

Corrosion ResistanceCorrosion resistance is probably the most common reason for choosing stainless steel. In addition to being resistant to rust, the austenitic stainless springs are resistant to a wide variety of chemical media and suitable for use in the food processing industry. A secondary reason is stainless steel is not as magnetic as carbon steel, but magnetism in stainless steel increases ...

A correctly designed spring, without any extraordinary stress will last indefinitely. Designing a spring based on its operating environment is necessary to increase the life of the spring. If the spring is in a corrosive environment, or under extreme temperatures, the proper material must be used in the design of the spring. Using a stainless steel material, or putting a protective finish on the s...
