DISC SPRINGS MATERIALS :
Springs in accordance with this standard shall be made from high-grade steel with a modulus of elasticity, “E” of 206,000N/mm2 as specified in either DIN 17221 or DIN 17222, it being noted that CK steel shall be used for the manufacture of group 1 springs only.
IIS can manufacturer Disc Springs from all the above materials. If one requires any other material, we can also use any material as per the customer’s requirement. IIS has in-house chemical and physical laboratory and so all the material is tested in-house before manufacturing. This ensures the quality of the Springs.
Deciding material is a crucial for a spring designer.A List of material used by us to manufacturer springs is available here
It is difficult to derive the amount of material required to be used in a spring based on the load vs. defl-ection requirement. Since Deflection is directly proportional to load, the amt. of material required to changes accordingly. Different materials have different tensile strengths, which are used in initial design calculations. The table below shows the approximate tensile strengths. |
