Titanium Grade 2 Flanges Manufacturer

Titanium Grade 2 flanges are widely recognized for their outstanding balance of strength, corrosion resistance, and formability, making them one of the most versatile grades of commercially pure titanium. These flanges are ideal for use in environments where long-term resistance to oxidizing agents, chlorides, and seawater is critical. With excellent weldability and moderate mechanical strength, Titanium Grade 2 flanges are often chosen for systems where reliability under corrosive stress is more important than extreme tensile strength.

Manufactured in a range of types such as weld neck, blind, slip-on, socket weld, and threaded designs, these flanges are engineered to meet demanding industry standards and dimensional tolerances. Their use is prevalent in chemical processing plants, marine applications, desalination units, and power generation facilities. Our flanges are produced with precision and quality control that align with global standards and are supplied across key industrial regions, including India, UAE, Saudi Arabia (KSA), Kuwait, Qatar, Oman, Iran, and Iraq.

Technical Overview

Titanium Grade 2 (UNS R50400) is a commercially pure, unalloyed titanium grade containing a minimum of 99.2% titanium, with carefully controlled levels of oxygen, nitrogen, hydrogen, carbon, and iron. This composition offers a unique combination of moderate tensile strength and exceptional resistance to corrosion in both oxidizing and mildly reducing environments. The mechanical properties include a tensile strength in the range of 344 MPa (50 ksi) and yield strength around 275 MPa (40 ksi), with excellent elongation and impact toughness.

These flanges are particularly valued for their weldability, ease of fabrication, and biocompatibility. They perform well in service temperatures up to 400°C (752°F), maintaining structural integrity and chemical resistance under sustained operating pressures. The manufacturing process is carefully optimized to minimize contamination and preserve the titanium’s surface purity, making them suitable even for high-purity and high-pressure applications.

Applications & Industry Use

Grade 2 Titanium flanges are extensively used in sectors that demand a high level of corrosion resistance without compromising on cost-efficiency and fabrication flexibility. In the chemical and petrochemical industries, they are utilized in piping systems handling acidic and chloride-rich fluids, offering long-term protection against pitting and crevice corrosion. In the marine sector, these flanges are ideal for shipbuilding, offshore platforms, and desalination systems due to their excellent resistance to seawater and marine atmospheres.

In the aerospace industry, Grade 2 titanium flanges are used in airframe components, fuel systems, and hydraulic lines, where weight reduction and corrosion resistance are critical. They are also applied in power generation, particularly in heat exchangers and condenser systems, and in medical and pharmaceutical manufacturing, where non-reactivity and purity are essential. With an established supply network across India, UAE, KSA, Kuwait, Qatar, Oman, Iran, and Iraq, our solutions cater to diverse industrial demands with precision, reliability, and consistent quality.
