S steel springs - Import export

Substitution of steel spring by S-Ply® leaf spring   Due to their  greater spring action, steel spring packages can be replaced by fewer or even one S-Ply® leaf spring for many applications.   Example:   a) Substitution   b) Cost calculation   Steel leaf spring: 155 x 25 x 2 mm 1 package of 10 springs   S-Ply® leaf spring: It is essential:   with: hS-Ply = Thickness of S-Ply® spring hStahl = Thickness of steel spring nStahl = Amount of steel springs EStahl = Modulus of elasticity (here 210.000 N/mm2) ES-Ply = Modulus of elasticity of S-Ply® leaf spring (here 28.000 N/mm2)   The result is that 10 steel leaf springs with a thickness of 2 mm each can be replaced by only 1 S-Ply® leaf spring with the thickness of 8,5 mm. Steel leaf spring* 10 pieces at 1,20 € = 12,00 € Intermediate package layers 18 pieces at 0,12 € = 2,16 € Total costs 14,16 € * purchase quantity > 1000 pieces, status 2009   S-Ply® leaf spring** 1 pc. at 4,13 € = 4,13 € shim plates (if applicable) 4 pc. at 0,12 € = 0,48

Spring steel is a model of load-bearing capacity. Characteristic for this material group are homogeneous microstructures and optimal surfaces. It stands for above-average service life, dimensional stability and constant quality in every end product. Spring steel obtains its special properties through special treatment in the production process, whereby the even distribution of the carbon content is of particular importance. It undergoes several rolling processes and repeated heat treatments in numerous work steps - this is how we guarantee optimum quality for your products! C 67 S - C 100 S/➔ according to DIN EN 10132 - 4 Depending on the customer's requirements, we supply treatment states from soft annealed to high cold solidified.
