List of the most important spring steels with material description, operating temperature, modulus of elasticity (E-modulus) and sliding modulus (G-modulus) as well as price index.

Compared to other steels, spring steel has a higher strength and can be deformed up to a certain tension (elasticity limit “Rp”). After relieving the load, the spring steel then returns to its starting position without being permanently deformed. Spring steel EN 10270-3-1.4310, for example, has a tensile strength of 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 to tensile strenght of the material that is normally used for spring steels> 85% lies. The elasticity as the main characteristic of a spring steel is achieved during the manufacturing process through a special alloy by adding silicon (Si), manganese (Mn), chromium (Cr), vanadium (V), molybdenum (Mo) and nickel (Ni).

What are the requirements for a spring material:

Spring steel must have a large elastic and sufficient plastic deformation capacity (winding of springs). It must have a high elastic limit, elongation at break and constriction at break, as well as a favorable creep and fatigue strength. In addition, the spring steel should have a low end carbonization and crack-free surface. A final heat treatment can increase the tensile strength of the spring steel.

Gutekunst Federn has most of these spring steels in stock with a round cross-section of 0.1 to 12.0 mm wire thickness. If you have a need for compression springs, tension springs, torsion springs and bent wire parts, click here for individual spring request .

The spring range in Gutekunst spring catalog is made of spring steel wire (EN 10270-1DH / SH) and stainless spring steel wire (EN 10270-3-1.4310). * Values at room temperature (20 ° C)
