TONG CHUANG GROUP deal with Stainless Steel and tube already more than 33 years， every year sell more than 80000 tons of Stainless Steel and tube. Our client already cover more than 65 countries. Our Stainless Steel and tube was width used in Mining， Energy， Petrochemical， Chemical Industry， Food plant， Paper plant， Gas and Fluid Industry etc.
Titanium has plasticity. The high-purity titanium has an elongation of 50 to 60% and a reduction in area of 70 to 80%. Despite the low strength of high-purity titanium， pure industrial titanium contains a small amount of impurities and the addition of alloying elements can significantly enhance its mechanical properties， so that its strength can be compared with high strength. This means that industrial pure titanium tubes can have both high strength and proper plasticity as long as they contain a small amount of interstitial impurities and other metal impurities.
The specific strength (strength to weight ratio) of industrial pure titanium pipes is very high in metal structural materials. Its strength is comparable to that of steel， but its weight is only 57% of that of steel. In addition， the titanium tube has a high heat resistance and maintains good strength and stability in an atmosphere of 500 °C. The titanium tube also has good low temperature resistance， and even at an ultra-low temperature of -250 °C， it has high impact strength and can withstand high pressure and vibration.
