The Titan XS is a round section mainspring made from the highest quality Swedish Grade One Vanadium Spring Steel
Each Titan XS spring is hand wound to exact specification, then heat treated and tempered to ensure ultimate performance and maximum durability. During the final tempering stage, they are coated with a specially formulated finish, a derivative of PTFE and Teflon that is hard yet flexible. Self-lubricating multislip properties eliminates the need for conventional spring lubrication, however grease application is still recommended. The almost friction free operation of the Titan XS Mainspring reduces the possibilities of dieseling to a minimum. Maximum power is maintained for longer than most other springs.
Titan XS Mainsprings do not lose power when left cocked for long periods.
