Titanium GR.5 Flanges
Titanium Grade 5 flanges are components used to connect pipes, pumps, and valves in high-performance systems. It is a strong, lightweight, and highly corrosion resistant flange. Made from a mix of 90% titanium, aluminum, and vanadium, they provide high strength and toughness even at elevated temperatures. Metracore Alloys is a leading manufacturer of Titanium Grade 5 flanges that meet international standards like ANSI/ASME B16.5 and B16.47 Series A & B. It offers excellent mechanical properties with a tensile strength of 138,000 psi and a yield strength of 128,000 psi. Its chemical makeup includes titanium, aluminum, and vanadium, which give it durability and long service life. These flanges are available in various types, including weld neck, slip-on, blind, socket weld, and threaded flanges.

The Titanium Grade 5 flanges come in sizes ranging from 1/2″NB to 60″NB. They are valued for their high strength-to-weight ratio and resistance to seawater and chemicals. It has a low density, high melting point, and reliable performance under stress. Their capacity to tolerate high pressure and harsh environments makes it ideal for demanding applications.
Our flanges are used in aerospace, marine, offshore oil and gas, and chemical processing plants. They are preferred in such industries because they do not corrode easily in harsh environments. We manufacture it using high-quality titanium alloy, precision machining, and strict quality checks. This ensures the final product is durable, accurate in dimensions, and fit for critical applications.
ASTM B381 Titanium GR.5 Flanges Stockist and Distributor
Every batch of titanium grade 5 flanges comes with certifications like EN 10204/3.1B, raw material certificates, 100% radiography test reports, and third-party inspection reports. Our team carefully bundles it to prevent damage during shipment. Options include wooden boxes, plastic wrapping, or customised packing to meet the client’s needs. This ensures safe delivery and maintains product quality from the factory to the site.
