CONVERSION TABLE

inches x 25.4 = millimeters

millimeters ÷ 25.4 = inches

1 lb = .454 kg

1 kg = 2.2 lbs

1 psi = .0007 kg/mm²

1 kg/mm² = 1422 psi

1 Newton(N) = .225 lbs. force

1 lb. force = 4.44 N

1 N/mm² = .102 kg/mm² = 145 psi
​
1 kg/mm² = 9.81 N/mm² = 1422 psi
When thickness, OA Hgt AND LOAD VALUES are specified, the controlling factor shall be the load shown. The tolerances shown in tables are for M series of material C1075 or AISI 6150. For tolerances on other series, such as stainless, SP, AI, etc. consult factory
Note: The tolerances shown in the tables are for M series of material C1075 or AISI 6150. For tolerances on other series, such as Stainless, SP, AI, etc. consult factory​
Materials: High grade spring steel of selected surface condition. Most commonly used are C-1075 or SAE 6150(50CRV4) Chrome vanadium steel. Other alloy steels are also used. We use 17-7 Ph stainless for corrosion resistance. It is slightly magnetic.

Hardness: Disc springs are carefully heat treated with austempering process and in such a manner as to prevent surface decarbonization. Allowable decarburization shall not exceed 3% of disc thickness.

Our Disc Springs are warranted for a period of one year from initial delivery to be free of defects and/or faulty workmanship. The limit of our liability in all classes is the free replacement of defective parts to be supplied as required Bulk package FOB Factory. In no case are claims for consequential damages permitted since we cannot misapplication of our springs or their use in inappropriate environments.
