1020 Steel Aerospace Belleville Washers - Request for Information

1020 Steel: is a plain carbon steel grade providing increased strength and ductility. 1020 steel retains integrity in basic structural applications while still being a low cost material.

Aerospace: deals with the development and manufacturing of products, structures, materials and devices used in aircrafts and spacecrafts. Aerospace industrial standards are established based on the extreme temperature, pressure and ware exposure faced in air and spacecraft operations.

Belleville Washers: are non-flat, cupped washes that provide load-bearing and deflection properties due to a subtitle conical shape. In addition to introducing spring and flexibility characteristics to the seal, Belleville washers function as locking devices in low dynamic load applications.

Washers: circular hardware used for spacing, load distribution, sealing and vibration reduction. Washers are produced through stamping and shaping a variety of materials including various metal, plastic, rubber and fiber.
