Titanium Grade 5 Fittings – Including Flanges, Elbows, Tees, Olets – ASME B16.5/B16.9/B16.11 – Exporter to 40+ Countries.
Titanium Grade 5, also known as Ti-6Al-4V, is an alpha-beta titanium alloy that offers an excellent combination of strength, corrosion resistance, and workability. It is the most commonly used titanium alloy globally, particularly in applications requiring superior mechanical performance and low weight. This alloy contains approximately 6% aluminum and 4% vanadium, which enhance its high-temperature strength and oxidation resistance. Titanium Grade 5 performs reliably in environments where both strength-to-weight ratio and resistance to extreme conditions are critical, making it ideal for industries like aerospace, defense, medical, and offshore engineering.
We supply a complete range of Titanium Grade 5 pipe fittings and flanges, including buttweld elbows, tees, reducers, end caps, stub ends, as well as forged socket weld and threaded fittings like couplings, unions, and bushings. Additionally, we offer outlet fittings such as weldolets, sockolets, elbolets, and threadolets, widely used in high-performance piping systems. All components conform to international standards like ASME B16.5, ASME B16.9, ASME B16.11, and MSS SP-97, and are available in pressure ratings from 150# to 600# with sizes ranging from ½” NB to 24” NB.
Titanium Gr.5 features outstanding mechanical properties, including a tensile strength of 895 MPa and yield strength of 828 MPa, while retaining excellent ductility and fatigue resistance. It maintains its strength at elevated temperatures up to 400°C and exhibits exceptional resistance to corrosion in seawater, chloride environments, and oxidizing agents. This makes it a preferred choice in heat exchangers, condensers, pressure vessels, and critical aerospace structures. The alloy is also biocompatible, which supports its use in medical implants and surgical tools.
All Titanium (Ti-6Al-4V) products are manufactured under strict quality control processes and in compliance with ISO 9001:2015 standards. Each fitting and flange undergoes rigorous inspection, including Positive Material Identification (PMI), ultrasonic testing, hydrostatic testing, and dimension verification. We maintain ready stock for fast delivery and offer full traceability with mill test certificates. With a strong global network, we serve major industrial clients across North America, Europe, the Middle East, and Asia-Pacific regions.
