SuperTherm from True Temper is a proprietary superthermophillic (heat-loving) alloy, developed in partnership with the U.S. Steel Alliance. The composition of Chromium, Molybdenum, and Vanadium with an unprecedented 217 ksi ultimate tensile strength makes this alloy actually gain strength through a metallurgical transformation in the heat-affected zone as a result of welding or brazing. SuperTherm is highly temper-resistant, resulting in an 11% increase in fatigue life and a 20% increase in impact strength heat treated 4130. The increased mechanical properties of SuperTherm allow for incredibly strong, yet lightweight frame designs with that legendary feel of steel ride quality.
