Butted/Air-hardening SuperTherm tube set SuperTherm 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 over 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.
Weightless Zinc Coating Gold or Black Freshly galvanized steel progresses through a natural
weathering process. During the first few weeks following galvanization, the zinc coating
develops a natural protective patina. If allowed to develop naturally, the patina itself provides
an inert corrosion protection layer for the active zinc metal.
Formation of the zinc patina begins with the exposure of freshly galvanized steel to atmospheric
oxygen. Initially, a thin layer of zinc oxide develops on the surface of the steel as a result of the zinc
metal and oxygen reacting. This oxide layer continues to react with water, rainfall, or dew, to form a porous,
gelatinous zinc hydroxide. During drying, this product reacts with carbon dioxide present in the atmosphere
and converts into a thin, compact, and tightly adherent layer of corrosion products consisting mainly of basic
zinc carbonate. The rate of patina formation varies according to the environmental conditions. Typically, it
takes 6 - 12 months to fully develop.
Research and corrosion testing have shown that zinc's ability to provide long-term corrosion protection
is mainly based on the formation of the zinc patina. This relatively insoluble layer of zinc corrosion products
inhibits the formation of new corrosion products by acting as a barrier to the underlying galvanized coating.
The patina also heals itself upon damage by reforming the corrosion products when fresh zinc metal is exposed
to the atmosphere.
We thought people would really appreciate the constant changing properties of zinc, along with the fact it is almost weightless.
