Spring steel classification

1.Carbon spring steel:The carbon content of carbon spring steel is generally 0.62% ~ 0.90%. According to its manganese content, it is divided into general manganese content (0.50% ~ 0.80%) such as 65, 70, 85 and higher manganese content (0.90 ~ 1.20%), such as 65Mn.
2.Alloy spring steel:Alloy spring steel is based on carbon steel, by adding one or several alloy elements appropriately to improve the mechanical properties, hardenability and other properties of the steel, in order to meet the performance required for the manufacture of a variety of spring steel. The basic composition series of alloy spring steel are silicon manganese spring steel, silicon chromium spring steel, chromium manganese spring steel, chromium vanadium spring steel, tungsten chromium vanadium spring steel, etc.

Applications Of Spring Steel

1.Applications include piano wire, spring clamps, antennas, springs, and vehicle coil springs, leaf springs, and s-tines.
2.Spring steel is also commonly used in the manufacture of metal swords for stage combat due to its resistance to bending, snapping or shattering.[dubious ]
3.Spring steel is one of the most popular materials used in the fabrication of lockpicks due to its pliability and resilience.
4.Tubular spring steel is used in the landing gear of some small aircraft due to its ability to absorb the impact of landing.
5.It is also commonly used in the making of knives.
6.It is used in binder clips.
7.Used extensively in shims due to its resistance to deformation in low thicknesses.
