Titanium rod gr7 has plasticity. High purity titanium rod gr7 elongation can be up to 50 ~ 60%, reduction of area of up to 70 ~ 80%. Despite the high purity titanium rod gr7 strength is low, but the pure industrial titanium rod gr7 contains a small amount of impurity and adding alloying elements can increase its mechanical properties, make its strength can be compared with high strength. That is pure titanium rods gr7 tube, as long as a small amount of interstitial impurity and other metal impurities, can make it not only has high strength, and a proper plastic. Than the strength of industrial ti6al4v eli pure titanium rods gr7 tube (strength and weight ratio) in metal structure material is very high, it has the strength of steel, but its weight is only 57% of the steel. In addition, gr7 titanium rod tube heat resistance is very strong, in the 500 ℃ in the atmosphere can still maintain good strength and stability. Gr7 titanium rod pipe also has good low temperature resistance, even in - under the temperature of 250 ℃, it still has the high impact strength, resistance to high pressure shock resistant. Of industrial pure titanium rods gr7 tube another remarkable characteristic is corrosion resistance is strong, this is due to its affinity for oxygen especially big, can generate on its surface a dense layer of oxide film, and can protect the titanium rod gr7 from corrosion medium. Therefore, titanium rods gr7 in acid, alkali, neutral salt aqueous solution and oxidizing medium has a good stability, than the existing stainless steel and other non-ferrous metal corrosion resistance are all well. Of ti6al4v industrial pure titanium rods gr7 tube application range is very wide, the current industrial pure titanium rods gr7 tube in the aerospace and aviation industry not only has very important application, and has been in chemical, petroleum, light industry, power generation, etc are widely used in many industrial departments.
Because of pure industrial gr7 titanium round bar titanium rod tube with light weight, strong strength, heat resistance, good corrosion resistance and many other features, is known as "the future of metal", is a very promising a new kind of structural material.
Characteristics: the gr7 titanium rod on tube surface, present continuous or discontinuous hair fine lines.
The reason:
1) tube billet with titanium sheet grade 5 subcutaneous blowhole or inclusions.
2) tube billet surface cleaning not thoroughly, there is a small crack.
3) roll excessive wear, aging.
4) roll machining titanium plate gr7 accuracy is bad, etc.
Inspection found: titanium bar gr7 pipe outside surface does not allow the existence of visible to the naked eye hair lines, such as there should be clear, clear after the wall thickness, outer diameter, the actual value shall not be less than the standard requires the most
