Disc springs of group 2 are stamped with a minimum material thickness of 1.25 mm up to and including 6.00 mm similar to the disc springs of group 1. These disc springs are exclusively manufactured from 51-CR-V4-steel.
The distinctive feature of this group of disc springs compared to group 1 is the additional machining at the inner and outer diameter. Furthermore, the edges at the inner and outer diameter are rounded.
A higher durability of the disc springs is achieved by surface finishing and phosphate coating processes.
Other surfaces are available according to customer-specific requirements.
