Factors to Consider When Selecting Disc Spring Materials

This white paper discusses the critical factors involved in selecting the appropriate raw material for Disc Springs. It outlines the significance of material choice in relation to force, operating environment, fatigue life, and cost. The document explains that carbon and alloy steel Disc Springs typically offer superior performance due to their springy nature and durability, especially when heat treated. However, it also notes that stainless steel variants provide better temperature resistance, albeit with limitations in extreme conditions. The paper emphasizes the complexity of material selection, particularly in applications requiring corrosion resistance or specific performance characteristics. It details how different materials, such as Inconel and various stainless steels, may be more suitable depending on the operational demands. The conclusion stresses the importance of consulting with Application Engineers to ensure the right material is chosen for achieving desired technical and commercial outcomes.
