Titanium Grade 1 and Grade 2 are commercially pure titanium grades that offer excellent corrosion resistance and low density. Grade 1 provides higher ductility and formability, while Grade 2 offers higher strength with good formability and corrosion resistance. The right grade depends on the required mechanical properties, fabrication process and service conditions.
Titanium grades are based on its compositional purity. An alloy’s purity can be determined by how much iron and other impurities it contains. The grade of titanium Gr 2 Round Bars is typically used to determine its quality, and there are three grades.
The alloy Grade 1 is extremely pure, with less than 0.7 percent iron, 0.5 percent nickel, less than 0.5 percent vanadium, less than 0.2 percent manganese, less than 0.1 percent cobalt, and less than 0.05 percent chromium.
As a grade 2, this alloy is slightly lower in purity and contains between 0.7 percent and 2 percent, with an approximate weight range between 80 percent and 90 percent. Titanium Gr 2 Round Bar are used are petrochemical, pharmaceuticals, oil and gas, pulp and paper, chemical specialty, seawater equipment and so on.

Applications of Titanium Grade 1 and Grade 2 Round Bars
Titanium Grade 1 Round Bars are suitable for applications where high ductility, formability and corrosion resistance are important. Titanium Grade 2 Round Bars are used where higher strength is required along with excellent corrosion resistance. Depending on the specification, applications include chemical processing equipment, marine components, heat exchangers, aerospace components and general industrial equipment.
Titanium is a particularly durable metal that has long been utilized in the aerospace sector. Additionally, it is the metal that is most frequently utilized in the manufacture of cars, ships, and even airplanes. Titanium is a fantastic material to utilize in these applications since it is both incredibly lightweight and corrosion resistant.
Round bars made of titanium Grade 1 are more than twice as strong as regular round bars. They have been heat treated to boost their strength and hardness, making them much more durable than traditional round bars.
Despite being less expensive than titanium grade 1 round bars, titanium grade 2 round bars still have several advantages over other types of steel, such as carbon steel or stainless steel
