Grade Gr7 is mechanically and physically equivalent to grade Gr2, except for the addition of the gap element palladium, which makes it an alloy. Grade Gr7 has excellent weldability and properties, and is the strongest corrosion resistance of all titanium alloys. In fact, it is the most corrosion resistant of the reducing acids.
Grade Gr7 is used for chemical processes and production equipment components.
Gr7 has extremely strong corrosion resistance, especially in reduced acidic environments.

When alloying elements are added to steel, iron and carbon, the basic components of steel, interact with alloying elements. The purpose of steel alloying is to improve the microstructure and properties of steel by the interaction of alloying elements with iron and carbon and the influence on the phase diagram of iron and carbon and the heat treatment of steel.
