What Is Grade 2 Titanium Sheet? — Product Overview
Grade 2 titanium sheet is a flat-rolled product manufactured from commercially pure titanium that has been processed through hot rolling, cold rolling, and annealing steps to achieve the desired thickness and mechanical properties. The "Grade 2" designation refers to the specific chemical composition defined by international standards such as ASTM B265 and ASME SB-265, which specify maximum permissible levels of oxygen, carbon, hydrogen, nitrogen, and iron. In practical terms, this sheet material provides a yield strength of approximately 275 MPa and a tensile strength ranging from 340 to 410 MPa, offering sufficient structural capacity for most load-bearing applications while maintaining remarkable ductility. The material is available in several common forms, including cold-rolled sheet, hot-rolled sheet, and titanium plate, with thicknesses differentiating sheets (0.4 mm to 6 mm) from plates (greater than 6 mm). Titanium 22, a premium titanium and alloy manufacturer, offers Grade 2 titanium sheet in a variety of sizes and surface finishes, supporting custom fabrication and precision machining for diverse industrial requirements. Because of its balanced property profile, this grade is often considered the default choice when product specifications require corrosion resistance, moderate strength, and cost efficiency.
When comparing Grade 2 titanium sheet with other mill products, it is helpful to understand the entire family of titanium materials available in the marketplace. The titanium materials portfolio includes sheets, plates, bars, tubes, wires, and custom machined components, where each product form serves specific engineering purposes. Grade 2 titanium sheet is especially favored for applications that involve welding, forming, and bending operations, because its low interstitial element content reduces the risk of brittleness in the heat-affected zone. The sheet also exhibits excellent fatigue resistance, allowing it to perform reliably under cyclic loading conditions that would cause premature failure in many other metals. In addition, Grade 2 titanium sheet offers a density of about 4.51 g/cm³, which is roughly 60 percent of the density of steel, making it an outstanding lightweight alternative for structural and non-structural components.
Key Characteristics and Specifications of Grade 2 Titanium Sheet
The mechanical properties of Grade 2 titanium sheet are the primary reason it is selected for demanding engineering applications across multiple sectors. The minimum yield strength of 275 MPa and ultimate tensile strength of 340–410 MPa ensure that components manufactured from this material can endure substantial mechanical loads without permanent deformation. The elongation at break, typically measuring 20 percent or more, means the sheet can be bent, stamped, and deep-drawn into complex geometries without cracking, which is a crucial advantage for fabricators creating intricate parts. Additionally, the material's excellent fracture toughness enables it to resist crack propagation even in the presence of surface defects, which directly translates to safer and more reliable finished products. When compared to commercial-purity Grade 1 titanium, Grade 2 titanium sheet offers higher strength while still maintaining an excellent level of ductility, striking an optimal balance that most industries require.
From a physical property standpoint, Grade 2 titanium sheet demonstrates characteristics that set it apart from other engineering materials. The melting point of approximately 1,670°C (3,038°F) means the sheet can maintain its structural integrity in high-temperature environments, although prolonged exposure to temperatures above 425°C can lead to oxidation and degradation of mechanical properties. The thermal conductivity is relatively low at around 21.9 W/m·K, which is useful for applications where thermal insulation or heat resistance is needed. Moreover, the corrosion resistance of Grade 2 titanium sheet is nothing short of exceptional, as the material spontaneously forms a thin, stable, and self-healing oxide layer when exposed to oxygen. This oxide film provides outstanding protection against seawater corrosion, chemical attack from acids and alkalis, and stress corrosion cracking that often plagues stainless steel in chloride-rich environments.
The available dimensions and tolerances of Grade 2 titanium sheet follow industry-standard specification tables that govern thickness, width, length, and flatness. Standard sheet thicknesses range from 0.4 mm to 6 mm, while widths can extend up to 3,000 mm and lengths up to 6,000 mm, accommodating both small precision parts and large structural panels. Thickness tolerances typically fall within ±0.05 mm for thinner sheets and ±0.15 mm for thicker sections, ensuring consistency that is essential for CNC machining and assembly-fit operations. The surface finish of the sheet can be specified as hot-rolled annealed, cold-rolled annealed, pickled, or polished, with each finish offering distinct surface roughness and aesthetic attributes. Titanium 22's range of titanium products includes high-quality sheets with certified dimensional accuracy, guaranteeing that manufacturers receive material that meets precise engineering specifications.
