1010 Steel Milspec Belleville Washers - Request for Information


1010 Steel: is a common, plain carbon, steel grade with minimal to moderate strength and toughness properties.  1010 steel is economical and often selected for low-demand, commonplace applications. 


Milspec: Military standards are most often defined by an efficient operation and substantial longevity in inhospitable or rugged conditions and environments.  


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.
