Precision engineered curved washers are available from in many stock sizes. These washers are made of finely tempered spring steel with some sizes being made of stainless steel. They come deburred and we have had all set removed during manufacture. Curved washers exert relatively light thrust loads and are often used to absorb axial end play. The rate is approximately linear between 10% and 80% of available deflection. Certificate of compliance available upon request - Certificate of chemical analysis available at extra cost.

Finish- Standard finish for high carbon steel is plain finish. Stainless steel is supplied in plain finish. On special order, high carbon steel washers may be mechanically plated, a process which substantially reduces the possibility of hydrogen embrittlement. Recommendations for specific applications will be made on request.

Material - Stainless Steel (Parts with suffix “S”) Commercial - Type 301 per ASTM-A666 (chemical only) & High Carbon Steel Commercial - 1074-1095 per ASTM-A684
