What kind of material does spring have?
Carbon spring steel: the material: 65#, 70#, 65Mn, 82B, 72A, 72B steel, is characterized by low plasticity, strong elasticity, anti stress ability. Application: mainly used for Simmons bed, car cushion, and all kinds of machinery, electric tools, stationery, sports equipment, torsion spring, spring, electrical equipment and other industries. Specifications: line diameter 0.20mm- GB4357-89 6.50mm. standard: carbon spring steel wire, national standard, main use: used to make cold formed in the cold state without hardening spring
In some specific occasions, such as pH and humidity, we often use stainless steel to make springs.The material of the die spring is usually made of chrome alloy steel. Chromium alloy spring steel has the characteristics of high temperature resistance, great rigidity and long service life.
Alloy spring steel: alloy spring steel is used to make spring or other elastic parts of steel. Spring is generally under alternating stress, the fatigue failure is a common failure forms, therefore, alloy spring steel must have high yield and yield ratio (s/ b) and the anti fatigue performance of elastic limit, and to ensure that the spring has enough elastic deformation ability and can withstand greater load. At the same time, alloy spring steel also requires a certain plasticity and toughness, a certain hardenability, not easy to decarburization and not overheating. Some special springs also require heat resistance, corrosion resistance, or a stable elasticity over a long period of time. Medium carbon steel and high carbon steel can be used as springs, but because of its hardenability and low strength, it can only be used to make smaller cross-section, less force of the spring. Alloy spring steel can produce important spring with large cross section and high yield limit
65MnSpring steel belongs to the mechanical structure steel; according to the quality grade, it belongs to the special quality steel, that is to say, in the process of production, it is necessary to strictly control the quality and performance of the steel.
