What are the factors affect spring selected material?

Believe everyone for spring materials have great understanding, but you know the spring material selection, shall be based on the nature of the spring load bearing, the working temperature, stress state, the service life of the conductive, the permeability of requirements, process performance, stress source of medium size, environment, material and price factors such as sure?
1, the material factors: spring usually choose simnvb 55, 55 si2mn simnmov, 55, 60 si2mna, 60 CRMNB, 60 CRMN brand of flat steel, etc. Medium and small springs, spiral extension spring, in particular, shall give priority to with strengthened steel wire, lead bath temperature, such as steel and oil quenching tempering steel wire pull, its strength, high surface quality, fatigue performance is higher than ordinary quenching tempering steel wire, and good manufacturability, processing is simple, stable quality. Large and medium-sized spring, in view of the load and stress of high precision, should choose cold drawn material or polishing after cold drawn steel; According to the low precision of load and stress, can choose hot rolled steel. To spring itself as a conductor of electric spring or under the condition of the uncertainty of the humidity, the water ( Including the sea) Spring, water environment, usually choose copper and steel. In acid type contact his work under the corrosive medium in the spring, usually choose stainless acid-resistant corrosion-resistant materials such as steel or nickel alloy. In normal ambient medium under the condition of application of spring, made from spring steel commonly, after the spring in its surface antirust coating or plating ( Zinc, cadmium plating, copper plating) The method of corrosion protection. Application of the spring in the weighing apparatus and instrument, in order to meet the accuracy is not affected by temperature change, usually choose elastic modulus and the expansion coefficient change very small constant elastic alloy. The prescribed qualitative light, insulation, crash-proof, corrosion-resistant special purposes such as spring, can choose reinforced plastics. Also can choose antivibration rubber manufacturing various types of rubber spring.
2, characteristic factors of strength, hardness and plane strain fracture toughness relationship greatly, therefore, its use should be based on spring load properties and stress. Hardenability, spring is the degree of hardening and hardening material section, the spring quality relationship is great. Spy, spiral spring material section, should first choose circular cross section. Square and rectangular cross section materials, although bear ability is stronger, impact resistant performance is good, but less source of materials, and the price is higher, except special must usually try not to choose this kind of material.
3 working under high temperature, temperature factors of spring material, demand intensity has good thermal stability, relaxation and creep resistance, oxidation resistance, must be medium corrosion resistance ability. Application in low temperature spring material, should have good toughness at low temperature. Carbon spring steel wire, piano wire and 1 cr18ni9 austenitic stainless steel spring wire, copper alloy, nickel alloy has good low temperature toughness and strength. Because under the condition of low temperature, material brittleness is sensitive to surface defects. Environmental medium on the material corrosion degree than in greenhouse, and cadmium and zinc plated easy cause cold short. Material of elastic modulus and the expansion coefficient change is not big, can not consider in the design.
There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their leaf spring hardware effects. However, recent studies have provided valuable insights into how the intake of may result in improved leaf spring hardware.
