Standard materials C60S 1. C67S 1. Normally this stainless steel is processed in forged form for disk thicknesses of more than 6 mm. Materials for special requirements Corrosive, high temperature and other aggressive environments require the use of materials. These materials, in general, have lower tensile strength than standard materials and should only be specified if absolutely necessary. These springs have a lower overall height than comparable sizes made of standard materials, resulting in lower spring force.

Standard materials C60S 1. C67S 1. Normally this stainless steel is processed in forged form for disk thicknesses of more than 6 mm. Materials for special requirements Corrosive, high temperature and other aggressive environments require the use of materials. These materials, in general, have lower tensile strength than standard materials and should only be specified if absolutely necessary. These springs have a lower overall height than comparable sizes made of standard materials, resulting in lower spring force.

This must be taken into consideration when using these materials. Corrosion-resistant materials X10 CrNi 1. Unfortunately, the cold forming process makes in magnetic. X7 CrNiAl 1. The cold forming process makes this material magnetic. X5 CrNiMo 1. However, it offers higher corrosion resistance and lower magnetism.

Small amounts of this material are hard to procure, and it is thus rarely used. High-temperature materials X22 CrMoV 1. X39 CrMo 1. This material grade has also proved very well for the use of heatresistant disc springs. Please bear in mind that both steel grades mentioned are not considered as corrosion-resistant steel grades. Anti-magnetic and corrosion-resistant materials CuSn 8 2.

Please bear in mind that the strength values and the spring forces resulting from it are considerably lower than with the standard material. CuBe 2 2. These copper alloys are absolutely anti-magnetic, and they have a very good electric conductivity. Furthermore they show a high corrosion resistance against many media. Heat-resistant special materials with a very good corrosion resistance Due to their composition, these nickel-base alloys show an excellent resistance against a lot of media.

Unfortunately, they are expensive and often hard to procure. This creeping is a function of temperature, time and tension. A disc spring can be used at higher temperatures, for example, when either a low load is chosen or the exposure time is accordingly short.

Thus a maximum working temperature cannot be stated. The values stated in the material grade overview table can therefore serve as a guiding value only. Materials Synoptic Table With regard to the maximum working temperatures listed it must be taken into consideration that the setting height of the springs depends on the height of the tensions occurring and on the operating time on temperature.

Furthermore, it has to be taken into consideration that with increasing temperature of the elasticity module of the material the strength diminishes. The operating temperature and thickness ranges can serve as reference values only. With heat-resistant steel grades, heat treatment and hardness deviate from the information given in the mentioned standards.
