Which spring steel wire is suitable for which application?

 

Spring steel wire compared to other steels has a higher strength and can be up to a certain voltage ( Elastic limit “Rp” ) are deformed. With this property, the spring steel wire returns to its original position after it has been relieved of stress, without being permanently deformed. For example, spring steel wire EN 10270-3-1.4310 has one tensile strenght from 1250 to 2200 N / mm² compared to 360 N / mm² for structural steel S235JR. The decisive difference here is the yield strength ratio, ie the ratio of Elastic limit tensile strength of the material, which is normally used in spring steels> 85% lies. The elasticity as the main characteristic of a spring steel wire is achieved by a special alloy: silicon (Si), manganese (Mn), chromium (Cr), vanadium (V), molybdenum (Mo) and nickel (Ni) are added in the manufacturing process.

 

Spring steel wires have a high tensile strength and a high elastic limit. This is made possible by the modulus of elasticity (Modulus of elasticity). To help in the manufacture of cold-formed Compression springs , Tension springs , Leg springs and bent wire parts to avoid overloading or breaks, the spring steel wires must have a very good plastic deformation capacity, which is why most spring steel wires are only heat-treated after the forming technique.

 

The following are the main properties of spring steel wires for the manufacture of Compression springs , Tension spring , Leg springs and Security elements at listed. In addition to the standard spring steel EN 10270-1 SH and DH, the dynamically demanding valve spring wire VDSiCr (Oteva 70) and the corrosion-resistant stainless steel grades 1.4310, 1.4401 and 1.4568, the non-magnetic spring bronze CuSn6 and the copper-beryllium spring steel CuB2 are also described here, as well as the Heat-resistant spring steel grades Nimonic 90, Inconel X-750 and Hastelloy C4. The price index (base 100) also shows the price ratio of the spring materials presented.
