Best Practices for Belleville Washers and Conical Disc Springs
American Belleville washers can be stacked to increase load capacity or deflection. They come in various materials like…
- High-carbon Steel Alloy AISI 1074 (ASTM A684)
- AISI 6150 (50CrV4/51CrV4) Chrome Vanadium Steel (ASTM A506)
- 301 Stainless Steel (ASTM A666)
- 17/7PH Stainless Steel (ASTM A693)
- Inconel 718 (ASTM B670 / AMS 5596)
- 510 Phosphor Bronze (ASTM B103)
Our washers can handle extreme temperatures (from -400°F to 1100°F), resist corrosion, and come in both magnetic and non-magnetic options. Additionally, several plating/finish options for our Belleville washers. These finishes not only look good but also protect the washers from the elements, ensuring they perform well and last a long time.
