What Is Gr7 Titanium Plate?
Grade 7 Titanium Plate is a particular kind of titanium alloy plate
that primarily consists of titanium with an addition of 0.12% to
0.25% palladium. This addition enhances its corrosion resistance
properties significantly. As a low-density alloy, Grade 7 titanium
exhibits superior corrosion resistance across various environments,
including exposure to seawater, industrial acids, and moderate
reducing conditions.
Its widespread use spans multiple sectors such as aerospace,
marine, chemical processing, and medical industries, owing to its
impressive strength-to-weight ratio coupled with outstanding
corrosion resistance. The versatility of Grade 7 titanium plate is
reflected in its availability in diverse sizes, thicknesses, and
specifications to cater to the specific demands of different
applications.
The production process for this titanium alloy involves melting
titanium together with the palladium. The resulting mixture is then
subjected to either hot or cold rolling processes to achieve the
necessary thickness and shape. Post-formation, the plate typically
undergoes annealing or stress-relieving treatments to enhance its
mechanical attributes. Furthermore, the plate can be finished with
a range of surface treatments like polishing, sandblasting, or
anodizing to meet the specific requirements of the end use.

Acid Regeneration
Grade 7 Titanium Plate is frequently utilized in acid regeneration
processes due to its exceptional resistance to corrosion,
particularly in highly acidic environments. Acid regeneration is a
crucial process within the chemical industry that involves the
recovery and subsequent reuse of spent acids such as hydrochloric
acid (HCl) and sulfuric acid (H2SO4), which are by-products of
various chemical reactions.
In the context of acid regeneration, Grade 7 titanium plate
material is commonly employed in the construction of acid tanks,
heat exchangers, and other related process equipment that come into
direct contact with these corrosive acids. The preference for Grade
7 titanium over other materials, like stainless steel, stems from
its unparalleled resistance to acid corrosion, especially in
applications involving high temperatures and pressures.
Referred to as Ti-Pd alloy, Titanium Grade 7 boasts enhanced
anti-corrosion properties thanks to the addition of 0.12-0.25%
Palladium. This increase in palladium content significantly
elevates its corrosion resistance beyond that of Titanium Grade 2.
With remarkable resistance to corrosion, the Grade 7 titanium plate
adeptly handles exposure to saltwater and is well-suited for
chloride media. Furthermore, it exhibits robustness against erosion
and impact, making it a prime choice for use in chemical plants.
These characteristics make it an ideal material for various stages
of chemical production processes and related equipment.
