What are the commonly used materials for Wave Springs?

Common Materials for Lispring Wave Springs:

1. .High Carbon Steel

• 65Mn: Commonly used grade in China
• SAE1070-1090: American grade

1. .Stainless Steel

• SUS631: Japanese standard designation
• 17-7PH: American standard designation
• 07Cr17Ni7Al: Chinese standard designation, a type of precipitation hardening stainless steel. Its strength can be enhanced through aging treatment, making it the preferred material for wave springs due to this characteristic.

1. .Special Alloy Materials

• A-286 (GH2132): Iron-based alloy, resistant to high temperature and corrosion, with a maximum recommended temperature of 538°C and relatively high cost-effectiveness.
• Inconel X-750 (GH4145): Nickel-based alloy containing 75% nickel, commonly used in acid-base environments, with a maximum recommended temperature of 538°C.
• Inconel X718 (GH4169): Nickel-based alloy with strong corrosion resistance, a maximum recommended temperature of 704°C, and commonly used in high-temperature environments. The wave springs used in our Tianwen-1 mission are made of this material.
