Superbti
is a professional company supplying high performance titanium bars, wire,
plates, forgings, tubes and fasteners.
1. High
strength
The strength
of titanium tube is high. Titanium alloy has a high strength, and its tensile
strength is 686 - 1176MPa, however, the density of titanium is only about 60%
of the density of steel, so the strength of titanium is very high.
2. High
hardness
The
hardness of titanium alloy (annealed) is HRC 32 - 38.
3. Lower
elastic modulus.
The
elastic modulus of titanium alloy (annealed) is 1.078 x 10-1.176 * 10MPa and
the elastic modulus of titanium is about 1/2 of that of steel and stainless
steel. In addition, the standard for titanium seamless tubes includes ASTMB337,
ASTMB338, and ASTMB861.
4. Excellent
properties in high temperature and low temperature environment.
At high
temperatures, titanium alloys can still maintain good mechanical properties,
and the heat resistance of titanium alloy is higher than that of aluminum
alloy. In addition, the working temperature range of titanium alloy is wider.
At present, the working temperature of the new heat resistant titanium alloy
can reach 550 - 600 DEG. At low temperature, the strength of titanium alloy is
higher than that at normal temperature, and it has good toughness, for example,
titanium alloys can maintain good toughness at -253 degrees centigrade.
5. Excellent
corrosion resistance.
When
titanium is in the air below 550 degrees, the surface will rapidly form a thin
and dense film of titanium oxide; therefore, in atmosphere, sea water, nitric
acid and sulfuric acid and other oxidizing medium and strong alkali, its
corrosion resistance is better than most stainless steel. Titanium seamless
tube is made by extrusion process, and welded titanium tube is welded by plate
bending. Under normal circumstances, the wall thickness of titanium seamless
tube is relatively small, and the caliber of titanium seamless pipe is
relatively small. Generally speaking, the outer diameter is smaller than
114.3mm that can be manufactured titanium seamless pipe, in contrast, titanium
tubes with an outer diameter greater than 114.3mm can only be produced titanium
welded tubes.
