Product Introduction

What's Gr7 titanium bar

GR7 titanium rods are made of Ti-0.15%Pd alloy and are specifically designed for chloride and strong oxidizing environments. They possess excellent acid and alkali resistance, high tensile strength, low density, good mechanical properties, wear resistance, and corrosion resistance, making them an ideal choice for industries such as chemical, corrosion-resistant equipment, heat exchangers, marine engineering, industrial, medical, aerospace, petrochemical, metallurgy, electroplating, vacuum coating, and sporting goods.

They are especially widely used in bleaching processes, chlor-alkali plants, and marine engineering, where superior resistance to crevice corrosion and stress corrosion is required.

Comparasion of Grade2 and grade 7

Choosing the right titanium rod is crucial for different corrosive environments. Grade 2 titanium rods are suitable for general corrosive environments, while Grade 7 titanium rods are specifically designed for chloride-containing environments, providing stronger protection. Understanding these differences will help you make more efficient and safer material choices.

Comparison Dimension	Grade 2 (pure titanium)	Grade 7 (palladium titanium alloy)
Chemical composition	Ti ≥ 99.2%	Ti ≥ 99.2%, Contains Pd 0.12–0.25%
Tensile strength	≥ 345 MPa ≥ 345	≥ 345 MPa ≥ 345
Yield strength	≥ 275 MPa ≥ 275	≥ 275 MPa ≥ 275
Corrosion resistance	Excellent, suitable for neutral or mildly corrosive environments.	It has excellent performance and is especially suitable for strong oxidizing or chlorine-containing environments.
Typical application environment	Seawater, fresh water, general chemical equipment	High concentrations of hydrochloric acid, sodium hypochlorite, wet chlorine gas, chlorine dioxide, and other highly corrosive media.
Cost	Low cost, suitable for large structural components	Although the cost is slightly higher, it is more economical in the long run in corrosive environments.
Application cycle	Under normal circumstances, depending on environmental factors, the service life is 5-8 years.	With a service life of 10-15 years, it reduces the need for frequent replacement and maintenance.

industry applications

Chemical industry

Grade 7 titanium bars are widely used in equipment for handling highly corrosive media, such as hydrochloric acid absorption towers, sulfuric acid storage tank supports, and hydrogen chloride gas pipeline supports. They are particularly suitable for environments containing chloride ions or strong oxidizing media, offering both structural strength and long-lasting corrosion resistance.

Marine engineering and desulfurization equipment

Due to their excellent resistance to chloride corrosion, they are widely used in seawater desulfurization towers, coastal equipment foundation reinforcement, and platform support rods. They are especially suitable for coastal or near-shore environments with high humidity and high salinity.

Pulp and paper industry

Chlorine dioxide (ClO₂) - suitable for corrosive areas such as bleaching and cleaning. Grade 7 titanium rods can be used for support structures, fixtures, and frame connections, thereby reducing equipment maintenance frequency and improving operational stability.

Energy and petrochemical industries

In oil refineries, desulfurization reactors, and chlorine-containing cooling water systems, Grade 7 titanium rods are commonly used in structural components such as heat exchanger tube sheet supports and flange connection reinforcements, effectively improving the system's corrosion resistance and service life.
