Spring material selection must be fully considering the purpose, importance and spring load of properties, size, cycle characteristics, working temperature, ambient medium, and the conditions of use, as well as the factors, such as machining, heat treatment and economy so as to make the selection results in conformity with the actual requirements. Steel is the most commonly used spring material. Nonferrous metals can be used when the force is small and requires anti-corrosion and anti-magnetic properties.
