Torque springs generate a virtually flat torque curve over the range of output turns and require steel that offers high performance across repeated cycles and constant load force. Such springs are subjected to high stresses through repetitive cycles and require a high level of reliability.
Paturle Aciers offers the C-Tex 80, proprietary textured steel which is produced by re-rolling a sorbitic hardened steel that offers outstanding mechanical properties that are required to manufacture high performance constant torque springs of exceptional strength and reliability.
