Normally Tolerance Rings and Strip are supplied in either Carbon Steel or Stainless Steel but can also be supplied in Inconel, Monel, Incalloy, Phynox, Copper-Beryllium and other suitable materials.
Hardness affects the point at which material will yield (elastic limit): For special designs we can heat treat carbon steel to a variety of hardness levels to achieve the desired characteristics. Varying grades of other material hardness can be used to obtain the desired characteristics.
Many thousands of specifications for different RENCOL® tolerance rings exist. We often create specific designs for high volume applications.
