Houston, USA-headquartered Louis Metals is a well-established producer and supplier of Titanium Grade 7 Forgings that excel in providing superior corrosion resistance even in extremely aggressive environments. Grade 7 is a commercially pure titanium alloy similar to Grade 2 but with a small addition of palladium, which significantly enhances its resistance to reducing acids and chlorides. Our forgings are produced with precision and care, ensuring excellent structural integrity and long-term performance. Louis Metals Titanium Grade 7 Forgings are extensively used in chemical processing, desalination, and marine applications where high durability, purity, and resistance to severe environments are required.
Louis Metals Titanium Grade 7 Forgings consist of titanium with the addition of a trace amount of 0.12–0.25% palladium, which supports corrosion resistance in reducing and acidic environments. Its mechanical properties are identical to Grade 2, including a tensile strength of ~344 MPa, and good ductility and weldability. This grade provides enhanced crevice corrosion and pitting resistance, especially in chloride-contaminated and acidic mediums like sulfuric and hydrochloric acid. It sustains performance over a broad range of temperature conditions and is perfect for applications requiring consistent corrosion resistance without compromising mechanical stability.

Yes, Titanium Grade 7 (Ti-0.2Pd) is highly corrosion-resistant, especially in harsh environments like seawater and acidic conditions, due to the addition of palladium, enhancing its ability to resist corrosion.
Titanium Grade 7 forgings are commonly used in industries like aerospace, chemical processing, marine, medical, and power generation due to their exceptional corrosion resistance, strength, and biocompatibility in challenging environments.
Titanium Grade 7 forgings are available in various sizes and shapes, including bars, billets, rings, discs, and custom configurations, typically ranging from small to large diameters for different industrial applications.
Titanium Grade 7 Forgings are widely utilized in the chemical processing industry for the handling of aggressive acids and chlorides. They are used in heat exchangers, reactor vessels, piping systems, and condenser tubing. Being resistant to crevice corrosion, they are perfectly suitable for marine and offshore conditions, particularly in seawater-cooled systems and ballast water systems. Grade 7 is also utilized in power plants, desalination plant equipment, and waste treatment plants. Its great weldability and endurance over the long term under severe conditions of exposure to the environment render it a choice material for corrosion-prone applications where longevity and safety are of utmost importance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
