Titanium Grade 2

Titanium Grade 2 is one of the most widely used commercially pure titanium grades, offering an excellent combination of high strength, good formability, and outstanding corrosion resistance. With its superior resistance to aggressive environments, Grade 2 titanium is ideal for demanding applications in the chemical, medical, aerospace, and marine industries, where durability and reliability are essential. Due to its castability, it is often used in the production of cast valves and fittings.

Titanium Grade 2 It provides exceptional corrosion resistance in a variety of acidic and alkaline environments, making it particularly suitable for use in piping, heat exchangers, and undercarriage components exposed to extreme conditions. This material is a preferred choice for applications that require lightweight, robust, and durable performance. Its excellent weldability and machinability also make Grade 2 titanium highly versatile, especially for manufacturing components that require high strength and low weight.
