Spring material selection should be based on the spring to bear on the nature of the load factors to determine the stress state, stress, size, operating temperature, environment, media, life, the requirements of the conductive permeability, process performance, sources of material and price.

Spring material of choice, and should be based on spring load stress state of the nature, size, and stress, temperature, environment, life, and media to the conductive lead magnetic requirements, process performance, materials sources and prices and other factors.

The spring material choice, should according to spring withstanding factor determinations and so on the load nature, stress condition, stress size, operating temperature, environment medium, service life, to lead electric conductance magnetism request, shop characteristics, material origin and price

Selection of the spring material should be based on the nature of spring loading, stress, stress, temperature, environment, media, life at work, conducting magnetic source of requirements, process performance, material and price and other factors to determine.
