Due to its unprecedented strength, lightness, stable and abundant
market and non-corrosive characteristics, titanium has emerged as
the metal of choice for aerospace, energy production and
transportation, industry and medical, leisure and consumer
products, notably golf clubs and bicycle frames. Furthermore, due
to its strength and lightness, titanium is currently being tested
in the automobile industry, which has found that the use of
titanium for connecting rods and moving parts has resulted in
significant fuel efficiency.

Most of the titanium grades are of alloyed type with various
additions of for example aluminum, vanadium, nickel, ruthenium,
molybdenum, chromium or zirconium for the purpose of improving
and/or combining various mechanical characteristics, heat
resistance, conductivity, microstructure, creep, ductility,
corrosion resistance, etc. Titanium BenefitsHigh strength,
High resistance to pitting, crevice corrosion resistance,
High resistance to stress corrosion cracking, corrosion fatigue and
erosion,
Cold bending for complex piping bends without fittings or flanges,
High strength to weight ratio.
Weight saving possibilities,
Low modulus, high fracture toughness and fatigue resistance,
Suitability for coiling and laying on seabed,
Ability to withstand hot/dry and cold/wet acid gas loading,
Excellent resistance to corrosive and erosive action of
high-temperature acid steam and brine,
Good workability and weldability. Titanium Chemical CompositionPalladium (Pd) and Ruthenium (Ru), Nickel (Ni) and Molybdenum (Mo)
are elements which can be added to the pure titanium types in order
to obtain a significant improvement of corrosion resistance
particularly in slightly reducing environments where titanium
otherwise might face some problems due to insufficient conditions
for formation of the necessary protective oxide film on the metal
surface. The formation of a stable and substantially inert
protective oxide film on the surface is otherwise the secret behind
the extraordinary corrosion resistance of titanium. The mechanical properties of commercially pure titanium are in fact
controlled by "alloying" to various levels of oxygen and nitrogen
to obtain strength level varying between approximately 290 and 550
MPa. For higher strength levels alloying elements, e.g. Al and V
have to be added. Ti 3AL 2.5V has a tensile strength of minimum 620
MPa in annealed condition and minimum 860 MPa in the as cold worked
and stress relieved condition. The CP-titanium grades are nominally
all alpha in structure, whereas many of the titanium alloys have a
two phase alpha + beta structure. There are also titanium alloys
with high alloying additions having an entire beta phase structure.
While alpha alloys cannot be heat treated to increase strength, the
addition of 2.5% copper would result in a material which responds
to solution treatment and ageing in a similar way to
aluminum-copper. Titanium DensityTitanium is more then 46% lighter than steel. For comparative
analysis, aluminum is approximately 0.12 lbs/cu.in, Steel is
approximately 0.29 lbs/cu.in, and Titanium is approximately 0.16
lbs/cu.in. Titanium Corrosion ResistanceTitanium's outstanding corrosion resistance is due to the formation
of a tightly adherent oxide film on its surface. When damaged, this
thin invisible layer immediately reforms, maintaining a surface
which is completely resistant to corrosive attack in sea water and
all natural environments. This oxide is so resistant to corrosion
that titanium components often look brand new even after years of
service. |
