How to choose spring materials for spring machines?

There are many kinds of springs used in production and life. Different materials are needed to produce different springs. The selection of spring materials for spring machines is based on the following points:

1. The basis for selecting the environmental factors of spring products in spring machine production is mainly: corrosion resistance (acid resistance, alkali resistance, salt corrosion resistance, water corrosion resistance), weather resistance, stress corrosion resistance, fatigue corrosion resistance, wear resistance, temperature resistance, resistance to various radiation, etc.

2. The basis for selecting the load characteristics of spring products is mainly: dynamic pulse cycle load, variable load, impact load, corrosion fatigue load, static load, large load and fatigue load.

3. The basis for selecting the mechanical properties and strength characteristics of spring products mainly includes: tensile strength, yield strength or yield ratio, hardness, thermosetting, cross-sectional shrinkage, elongation, impact toughness, relaxation performance, fatigue strength, fracture toughness, etc.

4. The basis for selecting the physical properties of materials used in the production of spring products by spring machines mainly includes: elastic modulus, density, conductivity, electromagnetic properties, heat transfer properties, etc.

5. The basis for selecting the process characteristics of spring product materials mainly includes: rolling performance, cutting performance, winding performance, torsion performance, bending performance, deformation strengthening, solid solution strengthening, precipitation strengthening, hardenability, hardenability, decarburization performance, tempering characteristics, aging performance, welding performance, etc.
