Product Description

What Is High Quality Gr7 Titanium Plate?

Grade 7 titanium plate is a high-end, corrosion-resistant titanium-palladium alloy plate designed for specialized applications. It is classified as a specialty industrial titanium alloy and is manufactured in strict compliance with the ASTM B265 international standard. The base material consists of high-purity industrial-grade titanium with a precise addition of 0.12% to 0.25% palladium, making it one of the commercial titanium grades with the strongest corrosion resistance currently available. Unlike conventional Gr1 and Gr2 pure titanium plates, Grade 7 titanium plates offer significantly enhanced performance under severe operating conditions—such as exposure to reducing acids, crevice corrosion, high-temperature corrosion, and corrosion in humid environments under negative pressure—effectively addressing the challenges posed by highly corrosive environments that ordinary titanium and Stainless Steel plates cannot withstand.

The core advantage of Gr7 titanium sheet lies in its palladium alloy strengthening, with palladium content precisely controlled between 0.12% and 0.25%. The titanium matrix has high purity, and interstitial impurities such as oxygen, iron, carbon, nitrogen, and hydrogen are strictly controlled, ensuring a uniform and stable composition. Palladium significantly enhances the self-healing ability of the Titanium Material’s passivation film and greatly improves the material’s stability in reducing corrosive media—a core characteristic not found in ordinary pure titanium material.

Key Advantages

1. Exclusive resistance to reductive corrosion, suitable for strong acid environments

Standard pure titanium is resistant only to oxidative media and is prone to corrosion and failure in hydrochloric acid, dilute sulfuric acid, and reducing organic acids. Gr7 titanium plate, modified with palladium, can be used stably over the long term in low-concentration hydrochloric acid, dilute sulfuric acid, and mixed reducing acid-base media, completely resolving the challenge of high-cost alternatives to standard titanium, stainless steel, and Hastelloy.

2. Exceptional Resistance to Crevice Corrosion and Pitting Corrosion

In confined crevices, damp interstitial spaces, salt fog-prone areas, and environments with media buildup, it is highly resistant to pitting, crevice corrosion, and intergranular corrosion. It is ideal for corrosion-prone hard-to-reach areas such as heat exchanger gaps, equipment linings, and sealing contact surfaces, effectively eliminating localized perforation and leakage issues.

3. Stable High-Temperature Corrosion Resistance

It withstands the erosion of corrosive media at temperatures up to 150°C. The passivation film does not decompose or fail in high temperature environments, and shows no aging or peeling during long term operation, making it suitable for high-temperature chemical reaction, evaporation, and concentration process equipment.

4. Excellent Weldability and Consistent Corrosion Protection Throughout

The welded areas retain excellent corrosion resistance after welding, eliminating the need for additional corrosion protection. Unlike ordinary titanium materials, these welds do not corrode or fail, ensuring uniform and consistent corrosion protection across the entire equipment. This makes it suitable for equipment fabricated from single piece welded plates.

5. Non-magnetic, clean, durable, and maintenance free

The titanium material is non-magnetic, non-toxic, and non-polluting; it does not interfere with precision equipment or contaminate chemical media or pharmaceutical solutions. Once the equipment is fabricated, there is no need for frequent anti-corrosion coating or replacement. Its service life is 8–15 times longer than that of 316L stainless steel, significantly reducing operation and maintenance costs.
