Titanium Grade 7 Sheet (UNS: R52400)

Titanium Alloy Grade 7 Sheet has outstanding corrosion resistance and useful strength at low density. A small addition of palladium has been made to this alloy for a substantial increase in corrosion resistance.

Titanium grade 7 sheet is a corrosion resistant alpha titanium alloy with similar mechanical properties to the commercially pure grades. It has a small palladium addition to improve corrosion resistance, particularly in mineral acids and strong brines. It is used mildly reducing or fluctuating conditions. At room temperature it is an alpha alloy. It transforms to beta phase at 913°C, and the alpha phase returns on cooling 890°C.

Titanium is reactive, with a very high affinity for oxygen, which forms a skin of very stable and highly adherent oxide. The skin gives excellent corrosion resistance, despite the reactivity of the metal. The oxide layer forms spontaneously and on exposure to the atmosphere. However, when new parent metal is exposed to anhydrous conditions or in the absence of air, rapid corrosion may occur. Care should also be taken if titanium is to operate in contact with hydrogen, as hydrogen embrittlement from hydride formation can increase strength, with loss of ductility.

The development of many different alloys has extended the application of titanium in industries ranging from industrial and chemical processing to power generation. This grade possesses good weldability, strength, ductility and formability. This makes Grade 7 titanium sheet is the prime choice for many fields of applications:

Titanium Corrosion Resistance

Titanium'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.
